A bomb calorimeter has a heat capacity of 3.82 kJ/°C. A sample of cinnamaldehyde is ignited in the calorimeter, resulting in a temperature increase from 24.53°C to 31.23°C. How much heat was created by the combustion of cinnamaldehyde?

THE HEAT CREATED BY THE COMBUSTION OF THE CINNAMALDEHYDE IS 25.594 JOULES.

Explanation:

When heat capacity of a substance is given, the heat evolved or used up in the process is the multiplication of the heat capacity and the temperature difference.

Heat = Heat capacity * change in temperature

Heat capacity = 3.82 kJ/°C

Change in temperature = 31.23 C - 24.53 C = 6.7 °C

So therefore, the heat created by the combustion of the cinnamaldehyde is:

Heat = 3.82 * 6.7

Heat = 25.594 Joules

In conclusion, 25.594 J of heat is created from the combustion of cinnamaldehyde

ill try to . no promises tho.
