Answer:

-129.69J or -0.129KJ

Explanation:

First, we must determine the number of moles of silver nitrate and potassium chloride involved in the reaction according to the balanced chemical reaction equation as shown in the question.

From the number of moles, we determine the limiting reactant(the one having the least number of moles). This is the used to obtain the heat evolved as shown in the image attached.
