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
