A. 26.7 kJ
B. -26.7 kJ
C. -178 kJ
D. 178 kJ
E. -632 kJ
F. 632 kJ

Answer 1

Answer:+178

Explanation:

Answer 2

The heat of the reaction for the following reactions is 178 kJ. the correct option is D.

What is the heat of the reaction?

The heat that is added or removed during a chemical reaction is called the heat of reaction.

It is also called the enthalpy of the reaction.

The heat is absorbed or released to maintain the temperature of the reaction.

The enthalpy can be calculated by subtracting the enthalpy of the product from the enthalpy of the reactant.

Thus, the correct option is D.
