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

6.4 cm (max) - 25 cm (min)

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
