answers
91.29 grams

2 grams

45.64 grams

1500 grams

91.29 grams

Explanation:

Endothermic reactions are those chemical reactions in which heat is absorbed by the reactants.

According to stoichiometry,

3352 kJ of energy is absorbed by  2 moles of

Thus 1500 kJ of energy will be absorbed by= of
