How much heat, in joules and in calories, must be removed from 3.52 mol of water to lower its temperature from 23.9 to 11.4°C? Include the sign in your answer

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

the correct answer would be d. hope this !
