The total bonding energy for the products of a reaction is 2535 kj/mol and the bonding energy of the reactants is 1375 kj/mol. calculate the change in enthalpy, and classify the reaction as endothermic or exothermic.

a) -1160 kj/mol, endothermic
b) -1160 kj/mol, exothermic

1160 kJ/mol

Explanation:

To get the enthalpy of the reaction take ΔH products- ΔH reactants

your parents i think this could be it

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
