Answers

Answer:

[CO2] > [N2] > [He]

Explanation:

The relative concentration of CO2, N2 and He depends on the solubility of each gas in water. The more soluble in water a gas is, the greater its concentration in aqueous solution.

Among the gases listed, CO2 is most soluble in water hence it is expected to have the greatest concentration in solution followed by N2. Helium gas is insoluble in water hence it has the least concentration in the aqueous solution.

What factor is mostly responsible for the form of matter?
time
temperature
pressure
weather

Answers

Temperature is mostly responsible for the form of matter. For instance, when raising the temperature you're adding energy. This energy gives the individual molecules and atoms the ability to overcome the forces that hold them together. This can be seen when a solid turns into a liquid or a liquid turns into a gas. However, when you're lowering the temperature you're removing energy. The lack of energy results in less movement from the atoms. Gases condense into liquid because the atoms don't have enough energy to stay away from each other. Liquids solidify because the atoms don't have enough energy to slide past each other and they get stuck in place. So in conclusion, temperature determines how how much energy atoms have that allow them to move at different speeds which determines the state of matter.

Convert 5.4g of NaCl to moles

Answers

Answer:

.0924 moles of NaCl

Explanation:

So you know you have 5.4 g of NaCl and you need to know how many moles there are in this amount of NaCl

You'll need to find the atomic mass of the compound NaCl to help you solve for moles Sodium (Na) on the periodic table has a mass of 22.99 Chlorine (Cl) on the periodic table has a mass of 35.45

Add these two together----> 22.99 + 35.45 = 58.44

Now you can calculate for moles

Written-out method:

5.4 grams of NaCl  |   1 mole of  NaCl              

                                | 58.44 grams NaCl                = .0924 moles of NaCl

Plug into calculator method:

(5.4 g of NaCl/ 58.44g NaCl= .0925 moles)

Explanation:

The pH of a solution refers to the negative logarithm of it's hydrogen ion concentration. Generally, the hydrogen ion concentration of an acid is always greater than that of its conjugate base. Hence, the conjugate acid always has a lower pH than the conjugate base.

This can be seen in the species, H3O^+ and H2O, HClO2 and ClO2^- etc.

What is an ionic compound ?

A chemical compound known as an ionic compound is one that contains ions bound together by the electrostatic forces known as ionic bonding. Despite having both positively and negatively charged ions, or cations and anions, the molecule is generally neutral.

The term "ionic bonding" refers to a bond in which the ionic character is greater than the covalent character, i.e., when there is a significant difference in the electronegativity of the two atoms, which makes the bond more polar (ionic) than in a covalent bond, where the electrons are distributed more evenly.

The Lewis structures are not frequently drawn for ionic compounds due to the electrical motion of electrons.

Thus, The Lewis Dot Structure for ionic compounds must demonstrate how the electrons are transported to create the ions in the compound.

Answers

The two properties which can be measured from the given information are streak and cleavage of the mineral.

What are minerals?

Minerals are naturally forming inorganic substances having crystal structure and metallic characteristics. They have a definite chemical composition and  homogeneity.

Streak is the color of powder form of mineral and cleavage is how the mineral cleave when we cut through a plane.  Hardness says how much hard the solid is.

When the mineral breaks into cubes when struck with a hammer, we measure its cleavage properties. The red trail on scrapping indicates the streak of the mineral.

Hence, the two properties we can measure from breaking by hammer and scrapping by an unglazed porcelain are its cleavage and streak.

A balloon containing methane gas has a volume of 1.03 L at 99.0 °C . What volume will the balloon occupy at 198 °C ?

Answers

Answer:

The balloon will occupy a volume of 1.32L.

Explanation:

Given the following data;

Original Volume, V1 = 1.03L

Original Temperature, T1 = 99°C

New Temperature, T2 = 198°C

To find new volume V2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

[tex] VT = K[/tex]

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

Converting T1, from Celsius to Kelvin = 273 + 99 = 372K

Converting, T2, from Celsius to Kelvin = 273 + 198 = 471K

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

Making V2 as the subject formula, we have;

[tex] V_{2}= \frac{V1}{T1} * T_{2}[/tex]

[tex] V_{2}= \frac{1.03}{372} * 471[/tex]

[tex] V_{2}= 0.0028 * 471[/tex]

V2 = 1.32L

Therefore, the balloon will occupy a volume of 1.32L at 198°C

. If you apply heat to the copper bar, its density will

Answers

Answer:

Decrease

Explanation:

Density is defined as the mass per unit volume. Density is highly influenced by temperature.

The density of metals and copper is inversely proportional to the temperature, it means density of copper decreases with an increase in temperature or when heated. This is so because when the copper is heated, the copper atoms start vibrating faster that allows the collision of atoms with each other faster and occupying more volume than before. As the copper atoms occupy more volume, the density of copper decreases.

Hence, the correct answer is "On applying heat the density of copper decreases".

what is the volume in cubic meter and in cubic decimeter of 2.0mol of nitrogen on gas at 1000c and 100,000pa? (R=8.31j/molk)​

Answers

Given parameters:

Number of moles of Nitrogen = 2.0mole

Temperature of the gas = 1000c

Pressure on the gas = 100000Pa

Gas constant R = 8.31J/molK = 0.082atmdm³mol⁻¹k⁻¹

Unknown:

Volume in cubic meter and cubic decimeter = ?

Solution:

The ideal gas law is given as;

       PV  = nRT

where P is the pressure on the gas

          V is the volume of the gas

         n is the number of moles

         R is the gas constant

         T is the temperature of the gas

Let us convert to appropriate units;

      1000°C to K;

       K  = 1000 + 273  = 1273K

100000Pa to atm;

           101325Pa  = 1atm

           100000Pa = 0.99atm

 Input the parameters and solve for the unknown;

      0.99 x V  = 2 x 0.082 x 1273

                   V  = 210.9dm³

to m³;

        1000dm³   = 1m³

        210.9dm³ = [tex]\frac{210.9}{1000}[/tex]   = 0.21m³

A sample of ammonia gas has a volume of 3213 mL at 11°C and a pressure of 822 torr. What will the volume of the gas be in liters if the
moles of gas and the temperature do not change but the pressure changes to 2.33 atm?

Answers

Answer:

We are given:

v1 = 3.2 L                   v2 = x L

p1 = 822 torr OR 1.08 atm        p2 = 2.33 atm

t1 = t2 = 284 k

From the Ideal gas equation:

PV = nRT

Since the number of moles (n), universal gas constant (R) and Temperature (T) are constant

PV = k      (where k is a constant)

it can also be written as:

P1V1 = k --------------------------(1)

Similarly,

P2V2 = k (where k is the same constant as before)----------(2)

Solving for V2:

From (1) and (2):

P1V1 = P2V2

Replacing the variables

1.08 * 3.2 = 2.33 * x

x = (1.08 * 3.2)/2.33

x = 1.5 L (approx)

Therefore, the final volume of the solution will be 1.5L
