What is the heat of a reaction, in kJ/mol, with a total reaction mixture mass of 72.6 g if the reaction of 0.15 mol of reactant A causes a temperature increase of 5.5 oC in a calorimeter? Assume that the reaction mixture has a specific heat of 4.184 J/g-oC.

there all right good

explanation:

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

c) should be the answer.
