Consider the following reaction.

2CH3OH(g)⟶2CH4(g)+O2(g)Δ=+252.8 kJ

Calculate the amount of heat transferred when 38.34 g of CH3OH is decomposed by this reaction at constant pressure.

For a given sample of CH3OH, the enthalpy change during the reaction is 373.0 kJ. What mass of methane gas is produced?

mass of CH4 produced:
