How to Calculate the Heat Produced from Chemical Energy

When a chemical reaction occurs and tries to make both compounds reach equilibrium, heat is released as the compound is created. This heat may cause issues and may even break specific instruments used in the mixture, thus making it very important to know the amount of heat the reaction produces.

1.) Write the Formula

Begin by writing the formula for the heat produced and transferred in a chemical reaction. This formula will be Q = mc?T, where Q is the heat transferred in Joules (J), ?T is the change of temperature(C), m is the mass in the reaction (kg), and c is the heat capacity of the mass. (J/kgOC)

2.) List Down the Given Numbers and Convert them Appropriately

After writing down the formula, you will now have to list out the given numbers to help you visualize the overall equation. Not only that, but you will need to convert the given numbers to the appropriate unit of measurement. This means that if the temperature change is in Fahrenheit (F), then you must do the necessary conversion required to change the unit to Celsius (C).

3.) Substitute the Given Numbers into the Formula

When you have finished writing down and converting the given numbers to the appropriate units, you will now need to substitute said numbers into the formula. This will help you easily have a reference to the overall equation, and can concisely explain how you came to the answer.

4.) Answer the Generated Equation

After substituting the given numbers, you will now need to answer the generated equation. This means that you will need to do the necessary calculations to arrive at the change transferring in heat.

5.) Convert the Answer if Needed

When you have obtained the answer in Joules, you may need to do specific calculations to convert them to the unit of measurement asked by the question. If that is not the case, then you may skip this step.
