Answer 1

The heat liberated when 1.89g of benzoic acid is burnt in a bomb calorimeter at 25∘C increases the temperature of 18.94kg of water by 0.632∘C. If the specific heat of water at 25∘C is 0.998cal/g deg, the value of the heat of combustion of benzoic acid is.

Answer 2

Answer:

771.1kcal

Explanation:

heat of combustion= mass* specific heat* temperature change
