Suppose you want to use a combustion chemical reaction to cook hot dogs and hamburgers. what type of reaction would you want? a an exothermic reaction that releases energy. b a reaction that destroys energy. c a reaction that creates energy. d an endothermic reaction that absorbs energy.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
