When calculating the enthalpy of a reaction, if the reactant has a coefficient of 2, what must be done to the δhf value of the reactant?

Explanation:

If the reactant has a coefficient of 2, it signifies that we have two moles of the reactant in that reaction. We simply multiply the  ΔHf, heat of formation of the reactant by 2 and we use it for the calculation.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
