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.

Only one reactant yields 2 or more products. meaning you will only have 1 product and it will break down into 2 or more products. eg. h2o -> h2 + o2

257 grams h2o i think

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

Ithink the answer is d
