Relate Enthalpy to Reactions Practice Test

For a reaction at constant pressure, $\Delta H$ is defined as $\Delta H = H(\text{products}) - H(\text{reactants})$. If $\Delta H = -30\ \text{kJ}$, which statement must be true?

A neutralization reaction is measured to have $\Delta H = -57\ \text{kJ}$ for the reaction as written. What should happen to the temperature of the surroundings during the reaction (assuming heat is not lost to the outside environment)?
