Answer:

Step-by-step explanation:

Heat is a reactant.

If the equation requires heat to occur, the reaction is endothermic

The equation would have this model

A + B + heat =====> C + D

If the equation gives away heat, then it is exothermic

The equation would look like this. (I'll use a common reaction)

CH4 + 2O2 - heat ===> CO2 + 2H2O

The heat is minus when it has to be given away.
