Question
Methanol is used as a solvent.State the meaning of the term solvent.
Solution
A solvent is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature. Water is a very common solvent and is known as the "universal solvent" due to its ability to dissolve many substances. In the context of the question, methanol is being used as the solvent, meaning it is the substance doing the dissolving to create a solution.

Dimethyl ether, a useful organic solvent, is prepared in two steps. In the first step, carbon dioxide and hydrogen react to form methanol and water:CO2(g) + 3H2(g) → CH3OH(l) + H2O(l) =ΔH−131.kJIn the second step, methanol reacts to form dimethyl ether and water:2CH3OH(l) → CH3OCH3(g) + H2O(l) =ΔH8.kJCalculate the net change in enthalpy for the formation of one mole of dimethyl ether from carbon dioxide and hydrogen from these reactions.Round your answer to the nearest kJ.kJ
