The reaction system
tankabanditka [31]

Answer:

e. As equilibrium is reestablished, the partial pressure of hydrogen decreases.

Explanation:

Hello,

In this case, for the given chemical reaction:

CS_2(g) + 4H_2(g)\rightleftharpoons CH_4(g) + 2H_2S(g)

Considering the Le Chatelier's principle which states that adding more reactant shifts the reaction towards the products, condition that is related with the doubling of the hydrogen partial pressure, we can notice that e. As equilibrium is reestablished, the partial pressure of hydrogen decreases since the addition of hydrogen will be used to form more methane and hydrogen sulfide, for that reason, its amount is decreased to reattain equilibrium.

Regards.

A calorimeter holds 50 g water at 22.0°C. A sample of hot iron is added to the water. The final temperature of the water and iro
makkiz [27]

The change in enthalpy associated with the change in the water’s temperature is 1254 J.

<h3>What is specific heat?</h3>

The amount of heat required to increase the temperature of one gram of a substance by one Celsius degree is known as specific heat.

Enthalpy change will be calculated as:

ΔH = -cmΔT, where

m = mass of water = 50g

c = specific heat of water = 4.18J/g°C

ΔT = change in temperature = 28 - 22 = 6 °C

On putting values in the above equation, we get

ΔH = -(4.18)(50)(6) = -1254 J

Hence change in enthalpy of the reaction is -1254 J.
