Question

Hello,
Sorry to bother you all, but i have a quick question.

If I needed to use heat in a reaction, for example, Ca(OH)2(s) + 2NH4Cl(s) = 2H2O(g) + 2NH3(g) + CaCl2(s)

Do I need to put "+heat" on the reactant side when writing my equation?

Thanks in advance! :)

Answer 1

You can do that but usually the word "heat" is written above the arrow. Also, the capital Greek letter "delta" is written above the arrow to indicate that heat is applied to the reaction. Remember the capital Greek letter delta looks like an equilateral triangle.

Answer 2

Do I have to put it, or can I just leave it out?
