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.kJ In the second step, methanol reacts to form dimethyl ether and water: 2CH3OH(l) →CH3OCH3(g) +H2O(l) =ΔH8.kJ Calculate 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.
