Answer:
P2 = 1250mmHg
Explanation:
V1 = 5.0L
P1 = 750mmHg
V2 = 3.0L
P2 = ?
According to Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.
P = k/V k = P*V
P1*V1 = P2*V2 = P3*V3 =........=Pn*Vn
P1 *V1 = P2 * V2
Solve for P2
P2 = (P1 * V1) / V2
P2 = (750 * 5.0) / 3.0
P2 = 3750 / 3
P2 = 1250mmHg
The final pressure of the gas is 1250mmHg

Answer:
7.86 moles of sodium chloride are produced.
Explanation:
Given data:
Moles of chlorine = 3.93 mol
Amount of sodium = excess
Moles of sodium chloride formed = ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Now we will compare the moles of sodium chloride with chlorine.
Cl₂ : NaCl
1 : 2
3.93 : 2×3.93 = 7.86
Chlorine is limiting reactant that's why we compare the NaCl with only number of mole of chlorine.
Thus, 7.86 moles of sodium chloride are produced.
