For exothermic and endothermic reactions, the value of enthalpy change respectively is?

Question

A balanced chemical reaction that includes the heat change (evolved or absorbed Delta H) during the reaction is called the thermochemical reaction. For exothermic and endothermic reactions, the value of enthalpy change respectively is 

Answer 1

For an exothermic reaction, the sign of ∆H is negative (-)

For an endothermic reaction, the sign of ∆H is positive (+)
