Question

The reaction shows 100 kj of energy is released when 1.0 mol c3h8 forms. 3c 4h2 = c3h8 100 kj how much energy is released when 2.0 mol c3h8 forms? 200 kj

100 kj
300 kj
400kj

Answer 1

The amount of energy released when 2.0 mol of C3H8 forms is 200 kJ, as it is a directly proportional relationship.

Step-by-step explanation:

The information shows that when 1.0 mol of C3H8 forms, 100 kJ of energy is released. This is a directly proportional relationship, meaning twice the amount of product (2.0 mol of C3H8) will release twice the amount of energy. So, when 2.0 mol C3H8 forms, the amount of energy released would be 200 kJ.
