Select all that is true for thermochemical equations.
A.
If the coefficients in a balanced equation are multiplied by 2, the enthalpy change must also be multiplied by 2.
B.
If a reaction is endothermic and the equation for the reaction is reversed, the enthalpy change becomes positive.
C.
If there is 1 mole H2O(l) on the reactant side of the equation and there is 1 mole H2O(g) on the product side, they are canceled from the equation.
D.
There are two ways to express thermochemical equations--one with the heat on the reactant or product side of the equation and one with delta H equals the heat change.
