Using the heat capacity of water (1 cal/g oC), determine how much energy was released by the combustion of the wax.

hello some part of your question is missing below is the missing part

1. Mass of water in the boiler 336.6g 2. Mass of wax burn 0.289g 3. Increased in the temperature 6.6 C

and change to Joules and to kilojoules

answer : 9.295 kJ

Explanation:

Calculate how much energy was released by the combustion of the wax

ΔT = 6.6°C

Note :The energy released by the combustion of wax is absorbed by the water

heat = mass * specific heat capacity * ΔT

        = 336.6 * 1 * 6.6  = 221.56 cal

convert;  221.56 cal to J

           = 221.56 * 4.184 = 9295.0 J

hence the energy released by the combustion of the wax = 9.295 kJ

can you attach the

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
