1) Reaction:

Mg(s) + 2HCl (aq) ----> H2(g) + MgCl2(aq)

2) Analysis

An increase in pressure affects directly the rate of reaction involving reactiong gases. Changing the pressure where there are only solids or liquids does not affect the rate of reaction.

This reaction is not an equilibrium, the reaction is only forward. So, the reacting components, Mg(s) and HCl(aq) are a solid and a liquid.

Therefore, the reaction is not affected by the change in pressure.

Answer: the reaction is not affected at all.

If 54.9 L of an ideal gas is cooled from 64 degrees C to 7 degrees C, what will the volume of the gas become?
sweet [91]

Answer:

Volume = 45.62L

Explanation:

Data;

V1 = 54.9L

T1 = 64°C = (64 + 273.15)k = 337.15K

T2 = 7°C = (7 + 273.15)k = 280.15K

V2 = ?

From Charles law,

The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant

V = KT, K = V / T = V1 / T1 = V2 / T2 = V3 / T3 =.........= Vn / Tn

(54.9 / 337.15) = (V2 / 280.15)

V2 = (54.9 * 280.15) / 337.15

V2 = 45.618L

V2 = 45.62L
