Explanation:
Reaction equation:
CO + 2H₂ → CH₃OH
All the species are in gaseous state and the equation is balanced.
Change in pressure only affects equilibrium involving a gas or gases.
Based on Le Chatelier's principle, an increase in pressure will shift the position of equilibrium to the side having smaller volume or number of moles and vice versa.
CO + 2H₂ → CH₃OH
3moles of gases 1 mole of gas
An increase in pressure favors the forward reaction. A decrease in pressure will favor the backward step.
Answer:
B. mass, volume
Explanation:
Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.

<u>Answer:</u> The chemical equation is 
<u>Explanation:</u>
There are 2 types of reactions that are classified based on enthalpy change:
- Endothermic reaction
- Exothermic reaction
Endothermic reactions: They are defined as the reactions where heat is absorbed by the reaction. The change in enthalpy of the reaction is always positive.
Exothermic reactions: They are defined as the reactions where heat is released by the reaction. The change in enthalpy of the reaction is always negative.
Given values:
Energy released for 1 mole of HCl reacted = -42.1 kCal
The chemical equation for the formation of ammonium chloride follows:
