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.

Answer : The mass of helium added to the cylinder was, 1.5 grams
Explanation :
Avogadro's law : It is defined as the volume of gas is directly proportional to the number of moles of gas at constant pressure and temperature.
or,
where,
= initial volume of gas = 2.00 L
= final volume of gas = 3.50 L
= initial moles of gas = 
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Now we have to calculate the mass of helium were added to the cylinder.
Mass of helium added = 3.5 - 2.00 = 1.5 g
Thus, the mass of helium added to the cylinder was, 1.5 grams
Answer:
you know it is what it is☠
Explanation:
Nonmetallic elements form ions by valence electrons to complete their outer shell. The valence electrons an element has in its outer shell, the easier it is to complete. The electron shells an element has, the easier it is to fill its outermost shell.
Answer:
%M = 16.2%
%N = 18.9%
%O = 64.9%
Explanation:
Mg(NO3)2
Atomic mass of Magnesium M = 24
Atomic mass of Nitrogen N=14
Atomic mass of Oxygen O=16
Molar mass of Mg(NO3)2 = 24 + (14+[16*3})*2
Mg(NO3)2 = 24 + (14+48)*2
Mg(NO3)2 = 24 + 124
Mg(NO3)2 = 148
Percentage composition;
Magnesium M= (24/148) × 100
Magnesium M=0.162 × 100 =16.2%
Oxygen O=(16*6/148) × 100
Oxygen O= 0.649 × 100 = 64.9%
Nitrogen N= (14*2/148) × 100
Nitrogen N=0.189 × 100=18.9%
