Answer

Explanation:

Step1: Determine reaction type

If $\Delta H<0$, the reaction is exothermic. Given $\Delta H = - 2220\ kJ<0$, so it is exothermic.

Step2: Analyze heat change for given mass

Since the reaction is exothermic, when reactants react, heat is released.

Answer:

This reaction is...: exothermic. Suppose 94.1 g of $C_3H_8$ react. Will any heat be released or absorbed?: Yes, released.
