Assuming it's a perfect gas, we have PV=nRT hence if T goes down, V goes down up. The volume will decrease.
Explanation:
a. Average kinetic energy is directly proportional to absolute Kelvin temperature of a gas.
Yes
b. There are no attractive forces and repulsive forces between gas molecules.
Yes
C. Atoms are neither created nor destroyed by ordinary chemical reactions.
No
d. The volume occupied by all of the gas molecules in a container is negligible compared to the volume of the container
Yes
The kinetic molecular theory is one of such theories used to explain the forces between molecules and the energy they posses.
According to the theory;
- The temperature of gas is proportional to the average kinetic energy.
- Molecules are independent of one another and the force of attraction and repulsion between them is negligible.
- volume occupied by gases is negligible compared to the volume of the container.
Law of conservation of matter states that "atoms are neither created nor destroyed by ordinary chemical reactions".

The earth has the moon captured in its gravity. this keeps the moon in an elliptical orbit
1) Write the balanced equation to state the molar ratios:
<span>3H2(g) + N2(g) → 2NH3(g)
=> molar ratios = 3 mol H2 : 1 mol N2 : 2 mol NH3
What volume of nitrogen is needed to produce 250.0 L of ammonia gas at STP?
First, convert the 250.0 L of NH3 to number of moles at STP .
Use the fact that 1 mole of gas at STP occupies 22.4 L
=> 250.0 L * 1mol/22.4 L = 11.16 L
Second, use the molar ratio to find the number of moles of N2 that produces 11.16 L of NH3
=> 11.16 L NH3 * [1 mol N2 / 2 mol NH3] = 5.58 mol N2
Third, convert 5.58 mol N2 into liters at STP
=> 5.58 mol N2 * [22.4 L/mol] = 124.99 liters
Answer: 124,99 liters
What volume of hydrogen is needed to produce 2.50 mol NH3 at STP?
First, find the number of moles of H2 that produce 2.50 mol by using the molar ratios:
2.50 mol NH3 * [3mol H2 / 2 mol NH3] = 3.75 mol H2
Second, convert the number of moles to liters of gas at STP:
3.75 mol * 22.4 L/mol = 84 liters of H2
Answer: 84 liters
