#Zn(s) + 2HCl(aq) rarr ZnCl_2(aq) + H_2(g)#

Energy produced from exothermic reaction: 110kJ

Explanation:

  • When creating a chemical equation, the energy produced from the shouldn't be placed with the rest of the equation. However the energy produced shouldn't be forgotten and should be placed bellow.

  • Make sure that the number of atoms for each element on the left side of the equation adds up to the the number of atoms for each element on the right side.
