Open PDF. Worksheet #1 … Webcase, the "Heat Term" is written right in the equation. (This is called a "thermochemical equation".) If the heat term is on the left side, it means heat is being used up and it’s endothermic. If the heat term is on the right side, heat is being released and it’s exothermic. Look at the following examples: 1.
