Answer:
11) the difference in heat energies between products and reactants
12) enthalpy change
Explanation:
The heat of reaction is defined as that energy released or absorbed as chemical substances participate in a chemical reaction. It is a term used to denote the change in energy as reactants change into products.
Another name of heat of reaction is enthalpy of reaction. It is a state function since it depends on the initial and final states of the system.

this is beta decay as the mass number stays the same but proton number changes, this is specifically beta minus as a neuron changes into a proton
Atomic number 70
weight 173
number of neutron = weight - Atomic number
= 173 -70
=103
