Explanation:

Consider this balanced chemical equation:

2 H2 + O2 → 2 H2O

We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:

100 H2 + 50 O2 → 100 H2O

This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:

5,000 H2 + 2,500 O2 → 5,000 H2O

Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:

12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O

These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?

2 H2 + O2 → 2 H2O

is the same balanced chemical equation we started with! What this means is that chemical equations are not just balanced in terms of molecules; they are also balanced in terms of moles. We can just as easily read this chemical equation as “two moles of hydrogen react with one mole of oxygen to make two moles of water.” All balanced chemical reactions are balanced in terms of moles.

Example 8

Interpret this balanced chemical equation in terms of moles.

P4 + 5 O2 → P4O10

Solution

The coefficients represent the number of moles that react, not just molecules. We would speak of this equation as “one mole of molecular phosphorus reacts with five moles of elemental oxygen to make one mole of tetraphosphorus decoxide.”

Explanation: just took the quiz on usatestprep

Answer:

50kg

Explanation:

Using the formula for potential energy, which is the amount of energy due to position;

P.E = m × g × h

Where;

m = mass (kg)

g = acceleration due to gravity (10m/s²)

h = height (metres)

According to the information provided in this question, m = ?, P.E = 2500J, h = 5m

Using P.E = m × g × h

m = P.E/gh

m = 2500/(5 × 10)

m = 2500/50

m = 50kg

The mass of the man is 50kg.

Answer:

19.32 g/cm³

Explanation:

The density will remain the same no matter how many times you cut the gold.  The density is g/cm³ or g/mL.  Density is essentially how many grams 1 mL of a compound weighs.

Answer:

[tex]\boxed {\boxed {\sf 19.32 \ g/cm^3}}[/tex]

Explanation:

Density is the mass per volume (g/mL or g/cm³). It is an intrinsic property. This means it is not dependent on the amount and all samples of the same substance have the same density.

Therefore, if a piece of gold has a density of 19.32 grams per cubic centimeter and it is cut in half, the two pieces will have the same density.

Answer:

It is D.

Explanation:

Answer:

Standard acid-base reaction in two stages:

Na2CO3 + HCl → NaHCO3 +NaCl

NaHCO3 + HCl → NaCl + CO2 + H2O

If only a small quantity of acid is added (and the overall solution remains above pH 7), the reaction would stop at stage 1 and you’d be left with an aqueous solution of sodium chloride and sodium bicarbonate. Adding more acid would lead to the bicarbonate being converted to carbon dioxide and water, with the CO2 coming out of solution as a gas and more sodium chloride being produced.

Answer:

When the ammonium ion, NH4+, is formed, the fourth hydrogen is attached by a dative covalent bond

Explanation:

because only the hydrogen's nucleus is transferred from the chlorine to the nitrogen. The hydrogen's electron is left behind on the chlorine to form a negative chloride ion.

Answer: Cooking gas is a Mixture

Explanation:

A pure substance is a substance which contains definite composition of only one type of component. Hence, it cannot be separated by physical means.

On the other hand, a mixture is a substance which contains two or more than two types of components and they can be separated by physical means as well.

Cooking gas is a made up of a combination of different hydrocarbons (methane, ethane , butane etc)  and thus is a mixture.

Answer:

The maximum number of moles of PH₃ that can be formed is 0.8 moles.

Explanation:

The balanced reaction is:

P₄ + 6 H₂ → 4 PH₃

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, you can use a simple rule of three as follows: If by stoichiometry of the reaction 6 moles of hydrogen react with 1 mole of phosphorus, 4 moles of hydrogen will react with how many moles of phosphorus?

[tex]moles of phosphorus=\frac{4 moles of hydrogen*1 mole og phosphorus}{6moles of hydrogen}[/tex]

moles of phosphorus= 0.667

But 0.667 moles of phosphorus are not available, 0.2 moles are available. Since you have less moles than you need to react with 4 moles of hydrogen, phosphorus will be the limiting reagent.

Then you can apply the following rule of three: if by stoichiometry 1 mole of P₄ forms 4 moles of PH₃, 0.2 moles of P₄ will form how many moles of PH₃?

[tex]moles of PH_{3} =\frac{0.2 moles of P_{4} *4 moles of PH_{3} }{1 mole of P_{4} }[/tex]

moles of PH₃= 0.8

The maximum number of moles of PH₃ that can be formed is 0.8 moles.

According to the text "After the sun spun to light, the planets of the solar system began to form. But it took another hundred million years for Earth's moon to spring into existence. There are three theories as to how our planet's satellite could have been created: the giant impact hypothesis, the co-formation theory and the capture theory."

Explanation:

It can be silent or neutral mutation that has no effect on the structure or functioning of the organism

OR

It can be a useful (advantageous to the organism)

or a harmful mutation (causes genetic disorders)

Mutation created during reproduction in one gene may some times results in a new trait in offspring that can be of good or bad to the offspring.

Genetic mutation is  modification to a small section of a genome's nucleotide sequence  One nucleotide is frequently replaced by another in point mutations; other changes involve the insertion or deletion of one or more nucleotides.

Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the two main causes of mutations.

The mutations occurred during reproduction most probably passes to the offspring as new a trait and commonly results in a genetic disorder. In some occasional cases these genetic variations can lead to silent or good characteristics.

Answer:

[tex]\boxed {\boxed {\sf 56 \ Joules}}[/tex]

Explanation:

We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.

[tex]q=mc \Delta T[/tex]

The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.

We know the variables and can substitute them into the formula.

[tex]m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C[/tex]

[tex]q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)[/tex]

Multiply the first numbers. The grams will cancel.

[tex]q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )[/tex]

Multiply again. This time the degrees Celsius cancel.

[tex]q= 56 \ J[/tex]

56 Joules of heat are needed.

Answer:

The temperature will be 384.7 K

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

[tex]\frac{V}{T} =k[/tex]

Having an initial state 1 and a final state 2, the following is true:

[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]

Solving:

[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]

T2= 384.7 K

The temperature will be 384.7 K
