Means that energy is
from a reaction.

A  negative ∆H means that energy is given off  from a reaction

Explanation:

If the reaction has negative ∆H value then the reaction is exothermic

If the reaction has positive ∆H value then the reaction is endothermic

When Heat energy is given in the equation itself

If it is present on the left side it means that heat is absorbed and the reaction is Endothermic

If it is present on the right side it means heat is given off and the reaction is exothermic
