Question

The equation, A + B + heat arrow AB, is an example of an exothermic reaction. Answer True False

Answer 1

Endothermic: heat is before the arrow: \(\text{heat} \rightarrow \)
Exothermic: heat is after the arrow: \(\rightarrow \text{heat} \)

Answer 2

\(\huge \sf A+B + \Delta \rightarrow AB~[Endothermic]\\\huge A+B \rightarrow AB+\Delta~[Exothermic]\)
