Explanation:
yes you got the right idea
I am assuming you are talking about Neon. The rate of diffusion is directly proportional to the molar mass of the gas. Since neon has a molar mass of 20.18 grams, the gas must have a lower molar mass and must be a gas at 273 Kelvin. There are several elements that fulfill this criteria: Hydrogen, Helium, Oxygen, Nitrogen, and Fluorine.
Answer:
Limiting reactant: Oxygen 
Explanation:
First write the balanced chemical equation:
given mass of methane =25g
molecular mass of methane=16g/mol
mole=1.5625mol
given mass of oxygen=50
molar mass of oxygen=32g/mol
mole=1.5625mol
from the above balanced equation it is clearly that,
1 mole of methane needs 2 moles of oxygen for complete reaction
Therefore,
1.5625 moles of methane needs 3.125 moles of oxygen for complete reaction but we have only 1.5625 moles of oxygen,
hence,
oxygen will be the limiting reactant and methane will be the excess reactant
Pressure is inversely proportional to volume. Therefore, the effect of pressure change is opposite to the effect of volume change. So when more gas is added to the chamber the total pressure of the chamber doesn't increase.
<h3>What are the different relations between pressure and volume?</h3>
- As the volume changes, the concentrations and partial pressures of both reactants and products change.
- As the volume decreases, the reaction shifts to the reaction side with fewer gas particles.
- As the volume increases, the reaction shifts to the side of the reaction containing more gas particles.
- As the pressure increases, the equilibrium shifts towards reactions with fewer moles of gas.
- As the pressure decreases, the equilibrium shifts to the side of the reaction with higher moles of gas.
- Moreover, the pressure change in the system due to the addition of the inert gas is not limited to this.
