Question

An exothermic reaction releases 86.5 kJ. How many kilocalories of energy are released?

Answer 1

Answer:

20.635 Kcal

Explanation:

1 Joule = 0.239 calorie

1 Kilojoule = 0.239 calorie

From the question, energy released = 86.5 KJ

in terms of KCal, energy released = 86.5 x 0.239 Kcal      

                                                         = 20.635 Kcal
