Answer:
a variable (often denoted by x ) whose variation does not depend on that of another.
Explanation:
You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent variable.For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age.

Write balanced equations for all the reactions in the catabolism of glucose to two molecules of glyceraldehyde 3-phosphate (the preparatory phase of glycolysis), including the standard free-energy change for each reaction. Then write the overall or net equation for the preparatory phase of glycolysis, with the net standard free-energy change.
Solution :
The balanced chemical equation are
The Catabolism of the glucose takes place in five stages :
1. Glucose + [tex]$ATP$[/tex] → glucose - [tex]$6$[/tex] - phosphate [tex]$+ ADP$[/tex] , [tex]$\Delta G^0=-16.7 \ kJ/mol$[/tex]
2. Glucose - [tex]$6$[/tex] - phosphate → Fructose - [tex]$6$[/tex] - phosphate , [tex]$\Delta G^0=1.7 \ kJ/mol$[/tex]
3. Glucose - [tex]$6$[/tex] - phosphate + [tex]$ATP$[/tex] → [tex]$ADP$[/tex] + Fructose - [tex]$1,6- \text{biophosphate}$[/tex], [tex]$\Delta G^0=-14.2 \ kJ/mol$[/tex]
4. Fructose - [tex]$1,6- \text{biophosphate}$[/tex] → dihydroxyacetonephosphate + glyceraldehyde [tex]$-3 - $[/tex] phosphate, [tex]$\Delta G^0=23.8 \ kJ/mol$[/tex]
5. Dihydroxyacetonephosphate → glyceraldehyde [tex]$-3 - $[/tex] phosphate , [tex]$\Delta G^0=7.5 \ kJ/mol$[/tex]
Therefore, the overall net equations
Glucose + [tex]$2ATP \rightarrow$[/tex] glyceraldehyde [tex]$-3 - $[/tex] phosphate + [tex]$2ADP$[/tex] [tex]$\Delta G^0=2.1 \ kJ/mol$[/tex]
An isolated atom of a certain element emits light of wavelength 655 nm when the atom falls from its fifth excited state into its second excited state. The atom emits a photon of wavelength 435 nm when it drops from its sixth excited state into its second excited state. Find the wavelength of the light radiated when the atom makes a transition from its sixth to its fifth excited state.
Answer:
[tex]\frac{1}{\lambda_{6-5}} \approx 752nm[/tex]
Explanation:
From the question we are told that
Light wavelength [tex]\lambda_l=655nm[/tex]
Light wavelength atom fall [tex]x_L=5th-2nd[/tex]
Photon wavelength [tex]\lambda_p=435nm[/tex]
Photon wavelength atom fall [tex]x_P=^th-2nd[/tex]
Generally the equation for the reciprocal of wavelength of emitted photon is is mathematically given by
[tex]\frac{1}{\lambda}=R(\frac{1}{ \lambda _f^2}-\frac{1}{\lambda _i^2} )[/tex]
Therefore for initial drop of 5th to 2nd
[tex]\frac{1}{\lambda_{5-2}}=R(\frac{1}{2^2}-\frac{1}{5^2} )[/tex]
Therefore for initial drop of 6th to 2nd
[tex]\frac{1}{\lambda_{6-2}}=R(\frac{1}{2^2}-\frac{1}{6^2} )[/tex]
Generally we subtract (5th to 2nd) from (6th to 2nd)
[tex]\frac{1}{\lambda_{5-2}}- \frac{1}{\lambda_{6-2}}=R(\frac{1}{2^2}-\frac{1}{5^2} )-\frac{1}R(\frac{1}{2^2}-\frac{1}{6^2} )[/tex]
[tex]\frac{1}{\lambda_{5-2}}- \frac{1}{\lambda_{6-2}}=R(\frac{1}{5^2}-\frac{1}{6^2} )[/tex]
[tex]\frac{1}{\lambda_{5-2}}- \frac{1}{\lambda_{6-2}}=\frac{1}{\lambda_{5-6}}[/tex]
[tex]\frac{1}{\lambda_{5-6}}=\frac{1}{4350nm}-\frac{1}{655nm}[/tex]
[tex]\frac{1}{\lambda_{5-6}}=1.33*10^{-3}[/tex]
Therefore for 6th to 5th stage is mathematically given by
[tex]\frac{1}{\lambda_{6-5}}=(1.33*10^{-3})^{-1}[/tex]
[tex]\frac{1}{\lambda_{6-5}}=751.879nm[/tex]
[tex]\frac{1}{\lambda_{6-5}} \approx 752nm[/tex]
40 POINTS!!! Ice at 0.0 degrees C is combined with 50.0g of water at 75.0 degrees C. Calculate the grams of ice present initially if the entire mixture comes to a final temperature of 25.0 degrees C after the ice melts. Specific heat of water is 4.18 J/goC. SHOW WORK!
Answer:
mi = 31.28 g
Explanation:
According to the law of conservation of energy:
[tex]Heat\ Gain\ by\ Ice = Heat\ Lost\ by\ Water\\m_iL = m_wC\Delta T\\[/tex]
where,
mi = mass of ice = ?
L = Latent heat of fusion of ice = 334 J/g
mw = mass of water = 50 g
C = specific heat of water = 4.18 J/g.°C
ΔT = change in temperature of water = 75°C - 25°C = 50°C
Therefore,
[tex]m_i(334\J/g) = (50\ g)(4.18\ J/g.^oC)(50^oC)[/tex]
mi = 31.28 g
what is the mass of 1.5 x 10^21 silicon atoms?
Answer:
0. 070g
Mass of 1 Si atom =28.08/6.022*1023
So mass 1.5 *1021*4.6629*10-23
Answer:
[tex]\boxed {\boxed {\sf 0.070 \ g \ Si}}[/tex]
Explanation:
We are given a value of atoms and asked to find the mass. We can complete this in 2 steps.
1. Convert Atoms to Moles
First, we have to convert atoms to moles. We use Avogadro's Number or 6.022 × 10²³. This is the number of particles (atoms, molecules, formula units, etc.) in 1 mole of a substance.
In this case, the particles are silicon atoms. We can set up a proportion.
[tex]\frac { 6.022 \times 10^{23} \ atom \ Si }{1 \ mol \ Si}[/tex]
Multiply by the value of atoms given.
[tex]1.5 \times 10^{21} \ atom \ Si *\frac { 6.022 \times 10^{23} \ atom \ Si }{1 \ mol \ Si}[/tex]
Flip the ratio. This allows the atoms of silicon units to cancel and leave the moles of silicon.
[tex]1.5 \times 10^{21} \ atom \ Si *\frac {1 \ mol \ Si } {6.022 \times 10^{23} \ atom \ Si}[/tex]
[tex]1.5 \times 10^{21}*\frac {1 \ mol \ Si } {6.022 \times 10^{23} }[/tex]
[tex]\frac {1.5 \times 10^{21} \ mol \ Si } {6.022 \times 10^{23} }[/tex]
[tex]0.002490866822 \ mol \ Si[/tex]
2. Convert Moles to Grams
Next, we convert the moles to grams. We use the molar mass, which is found on the Periodic Table. This value is the number of grams in 1 mole of a substance. Look for silicon (Si).
Si: 28.085 g/molUse this value as a ratio.
[tex]\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
Multiply by the number of moles we calculated.
[tex]0.002490866822 \ mol \ Si *\frac {28.085 \ g \ Si}{1 \ mol \ Si}[/tex]
The moles of silicon units cancel, so we are left with grams.
[tex]0.002490866822 *\frac {28.085 \ g \ Si}{1}[/tex]
[tex]0.002490866822 *{28.085 \ g \ Si}[/tex]
[tex]0.06995599469 \ g \ Si[/tex]
3. Round
Finally we must round our answer. The original value has 2 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.
[tex]0.069\underline95599469 \ g Si[/tex]
The 9 tells us to round the other 9 to a 0, then the 6 to a 7.
[tex]0.070 \ g \ Si[/tex]
The mass of 1.5 × 10²¹ silicon atoms is 0.070 grams of silicon.
(a) Using the expression Ka=[H+][A−][HA] , explain how to determine which solution has the lower pH , 0.10MHF(aq) or 0.10MHC2H3O2(aq) . Do not perform any numerical calculations.
Answer:
Ka=[H+][A−]/[HA]
which solution has the lower pH, 0.10MHF(aq) or 0.10MHC2H3O2(aq) :
Higher value of Ka indicates greater ionization thus more protons in solution, higher H+ concentration in solution means lower pH value.
Since HF have higher Ka have, thus HF solution will have lower pH.
The measurement is when the solution has the lower pH so HF should have higher ka.
Measurement when the solution has the lower pH?In the given solution, it contains the lower pH, 0.10MHF(aq) or 0.10MHC2H3O2(aq).
Here higher value of Ka represents the high ionization so there should be more protons in the solutions. and, the higher h+ concentration have the lower pH value.
So in the case when HF has higher Ka, due to this, HF solution will have lower pH.

Describe the process used to determine how many atoms of each element are in 2Ca3(PO4)2. Show all
your work.
Answer:
Six atoms of calcium, four of phosphorous and sixteen of oxygen for a total of twenty six
Explanation:
Hello there!
In this case, according to the molecular formula of the two moles of calcium phosphate:
[tex]2Ca_3(PO_4)_2[/tex]
Thus, in order to calculate the atoms of each atom, it is necessary to multiply the two in front of the formula by the subscripts in the reaction:
[tex]atoms Ca=2*3=6\\\\atoms P=2*2=4\\\\atoms O=2*2*4=16[/tex]
Thus, we obtain six atoms of calcium, four of phosphorous and sixteen of oxygen for a total of twenty six.

Draw curved arrows to show electron reorganization for the mechanism step below. (For a resonance-stabilized anion, draw a single resonance form with the negative charge on oxygen, not on carbon.) Make the ends of your arrows specify the origin and destination of reorganizing electrons.
Answer:
Explanation:
Dear student, this question appears to be incomplete but in the diagram attached below, I have carefully drawn out the required organic structure.
The aim of this question is to show the mechanism of the given structure and to point out the resonance structure.
The first diagram shows the complete part (i.e. the structure of the organic compound) and its major product(answer).
The second diagram shows the mechanism by which we arrived at the major product.
From the second diagram attached below, the -oxo substituent of the methanol attacks the hydrogen atom as shown below, leading to the formation of the enolate ion (a resonance stabilized anion).
However, this is because the alpha carbon attaches to the hydrogens readily leaves as H⁺ to yield an enolate ion as a result of -C- that is doubly bonded to oxygen (an Electron withdrawing group).
Kindly check out the images attached below to see the mechanism.

Answer: When two hydrogen atoms pair together, they form a single bond to achieve a complete duet which is a stable configuration.
When two halogens poir together,they form a single bond to achieve a complete octet which is a stable configuration
When two oxygen atoma pair together, they form a double bond to achieve a complete octet which is a stable configuration
When two nitrogen atoms pair together, they form a triple bond to achieve a complete octet which is a stable configuration
Explanation:
The tendency of atoms to achieve a noble gas configuration that is eight valence electrons is said to be octet rule. This is done to attain noble gas configuration and stability.
In order to attain stability the atoms tends to have eight electrons in its valence shell which can be obtained by either by sharing of electrons or complete transfer of electrons.
Hydrogen [tex](H:1s^1)[/tex] has one valence electron each, so sharing of electrons result in formation of single bond and the same electron configuration as the Helium and thus complete its duet.
Halogens [tex](F:1s^22s^22p^5)[/tex] have 7 valence electron each, so sharing of electrons result in formation of single bond. The stable noble gas configuration is attained and thus complete its octet.
Oxygen [tex](O:1s^22s^22p^4)[/tex] has six valence electrons each, so sharing of two electrons result in a double bond. The stable noble gas configuration is attained and thus complete its octet.
Nitrogen [tex](N:1s^22s^22p^3)[/tex] has 5 valence electrons, so sharing of three electrons result in a triple bond. The stable noble gas configuration is attained and thus complete its duet.
Did entropy increase or decrease?
1) 2 SO3 (g) → 2 SO2 (g)+O2 (g)
2) MgCO3 (s) + 2 H3O^+ (aq) → Mg^2+ (aq) + 3 H2 O(I) + CO2 (g)
Answer:
1) increase
2) increase
Explanation:
Entropy is the degree of disorderliness or randomness of a system. It is the measure of the unavailable energy in a system.
Entropy increases with increase in the number of particles. If the number of particles in a system increases from left to right, the entropy of the system increases accordingly.
In reaction 1, the number of particles from left to right increased from two to three hence the entropy was increased.
In reaction 2, the number of particles from left to right increased from three to five hence the entropy was increased.
If the solubility of sodium chloride is 36 grams per 100 grams of water, which of the following solutions would be considered unsaturated? If the solubility of sodium chloride is 36 grams per 100 grams of water, which of the following solutions would be considered unsaturated? 3.25 moles of NaCl dissolved in 500 ml of water 1.85 moles of NaCl dissolved in 300 ml of water 5.8 moles of NaCl dissolved in 1 L of water none of the above
Answer: If the solubility of sodium chloride is 36 grams per 100 grams of water then 5.8 moles of NaCl dissolved in 1 L of water solution would be considered unsaturated.
Explanation:
A solution which contains the maximum amount of solute is called a saturated solution. Whereas a solution in which more amount of solute is able to dissolve is called an unsaturated solution.
Now, the number of moles present in 36 g of NaCl (molar mass = 58.4 g/mol) is as follows.
[tex]No. of moles = \frac{mass}{molar mass}\\= \frac{36 g}{58.4 g/mol}\\= 0.616 mol[/tex]
This shows that solubility of sodium chloride is 36 grams per 100 grams of water means a maximum of 0.616 mol of NaCl will dissolve in 100 mL of water.
So, a solution in which number of moles of NaCl are less than 0.616 mol per 100 mL then the solution formed will be an unsaturated solution.
As 5.8 moles of NaCl dissolved in 1 L (or 1000 mL) of water. So, moles present in 100 mL are calculated as follows.[tex]Moles = \frac{5.8 mol}{1000 mL} \times 100 mL\\= 0.58 mol[/tex]
Moles present in 100 mL of water for 3.25 moles of NaCl dissolved in 500 ml in water are as follows.[tex]Moles = \frac{3.25 mol}{500 mL} \times 100 mL\\0.65 mol[/tex]
Moles present in 100 mL of water for 1.85 moles of NaCl dissolved in 300 ml of water are as follows.[tex]Moles = \frac{1.85 mol}{300 mL} \times 100 mL\\= 0.616 mol[/tex]
Thus, we can conclude that if the solubility of sodium chloride is 36 grams per 100 grams of water then 5.8 moles of NaCl dissolved in 1 L of water solution would be considered unsaturated.
The air temperature in a sealed, insulated box.. 20°C An ice cube at O'C is
placed in the box where it slowly melts. How and why does the melting of the ice
affect the air temperature in the box?
Melting is endothermic so the air temperature increases
Melting is exothermic, so the air temperature decreases
Melting is endothermic, so the air temperature decreases
Melting is exothermic, so the air temperature increases
Answer:
Melting is endothermic, so the air temperature decreases.
Explanation:
Hello there!
In this case, according to the given statement, it is possible to infer that the ice is melt because energy is applied to the ice and thereafter its temperature increases; this is possible because the joined particles of a solid substance need energy to undergo such a separation that they become more far away to each other and therefore transcend to the liquid phase due to the new molecules arrangement. Thus, the answer is Melting is endothermic, so the air temperature decreases because as the ice heats up, the air cools down as it gives it energy to the ice.

Answer:
1. Distance = 5 cm
Displacement = 1 cm
2. Distance = 7 cm
Displacement = 1 cm
3. Distance = 5 cm
Displacement = -1 cm
4. Distance = 6 cm
Displacement = -2 cm
5. Distance = 4 cm
Displacement = 0 cm
Explanation:
The distance an object travels is a measure of the total ground cobpvered bybthe object without regard to the direction of motion. It is a scalar quantity as it only takes into account magnitude but not the direction of a quantity.
Displacement however, is a measure of how far away or apart an object is from its starting position. It a vector quantity as it takes into account both the magnitude and direction in its measurement.
From the attachment provided, considering forward direction as positive and reverse as negative :
1. When a object moves from point 1 to point 4 and reverses to point 2.:
Distance = from 1 to 4 = 3 cm; from 4 back to 2 = 2 cm; 3 + 2 = 5 cm
Displacement = from 1 to 4 = +3 cm; from 4 back to 2 = -2 cm; 3 - 2 = 1 cm
2. When an object moves from point 1 to 5 and reverses to 2:
Distance = from 1 to 5 = 4cm; from 5 back to 2 = 3 cm; 4 + 3 = 7 cm
Displacement = from 1 to 5 = +4 cm; from 5 back to 2 = -4 cm; 4 - 3 = 1 cm
3. When an object moves from point 1 to 3 and then reverses to 0.
Distance = from 1 to 3 = 2 cm; from 3 back to 0 = 3 cm; 2 + 3 = 5 cm
Displacement = from 1 to 3 = +2 cm; from 3 back to 0 = -3 cm; 2 - 3 = -1 cm
4. When an object moves from point 3 to 5 and then reverses to 1:
Distance = from 3 to 5 = 2 cm; from 5 back to 1 = 4 cm; 2 + 4 = 6 cm
Displacement = from 3 to 5 = +2 cm; from 5 back to 1 = -4 cm; 2 - 4 = -2 cm
5. When an object moves from point 2 to 4 and then reverses to 3.
Distance = from 2 to 4 = 2 cm; from 4 back to 2 = 2 cm; 2 + 2 = 4 cm
Displacement = from 2 to 4 = +2 cm; from 4 back to 2 = -2 cm; 2 - 2 = 0 cm

Answer:
B. aq if the reaction is inorganic (double or single displacement), neutralization, etc.
Explanation:
Hello there!
In this case, unfortunately we are not given the undergoing chemical reaction; however, in the most of the double displacement, neutralization, precipitation and in general, inorganic reactions, the hydrochloric acid must be B. aq as it must be dissolved in water as the reaction media. On the other hand, in some organic reactions, it can be either aqueous or gaseous, the latter, specially as a product. For that reason, you will need to make sure whether your reaction is organic or inorganic to correctly figure out the phase label.

Answer:
C is the correct answer.
Explanation:
We can eliminate some answers immediately:
A is incorrect because nitrogen and hydrogen do not change their identity, they just combine into a new molecule that contains them. Notice how there are 2 nitrogen atoms and 6 hydrogen atoms on both sides of the equation.
B is incorrect because the first law of thermodynamics tells us that matter and energy will always be conserved, so the mass of the products must be equal to the mass of the reactants, not less than the mass of the reactants.
C is correct because balanced chemical equations help chemists predict how much product will form from certain amounts of reactants.
D is incorrect because this equation is showing the exact opposite. Molecular hydrogen and nitrogen can combine stoichiometrically to form ammonia.
