Achemical reaction gives off 1,500 kj of heat energy. about how many calories is this? (1 calorie = 4.18 joules)

Answer : The heat energy in calorie is

Explanation :

As we are given the conversion for heat energy.

or,

As we are given that:

Heat energy in kJ = 1500 kJ = 1500000 J

conversion used : (1 kJ = 1000 J)

Now we have to determine the heat energy in calorie.

As,

So,

Therefore, the heat energy in calorie is

the atomic mass is the bottom number on the element.
