Hello!

The reaction that took place was B) exothermic. 

The equation for the ΔH is 

\Delta H= H products - H reagents

To know if this reaction is exothermic or endothermic we will need to look at the sign of the ΔH. If it is positive, it means that enthalpy of the products is higher than the enthalpy of the reagents and the reaction is endothermic.

If the sign is negative, it means that the enthalpy of the products is lower than the enthalpy of the reagents and the reaction is exothermic. In this case, the sign is negative, so the reaction is exothermic.

Have a nice day!
