Calculate the heat of combustion of a compound z , if 0.06 of heat on burning raise the temperature of 400gm of water by 10k (specific heat of water = 4.2)
To calculate the heat of combustion of compound z, we can use the formula:
Heat = mcΔT
Where:
m = mass of water = 400g
c = specific heat of water = 4.2 J/g°C
ΔT = change in temperature = 10K
Now, we know that 0.06 of heat on burning raises the temperature of 400g of water by 10K. So, let's calculate the total amount of heat generated by the combustion of compound z first:
Total heat generated = 0.06 * mcΔT
Total heat generated = 0.06 * 400g * 4.2 J/g°C * 10K
Total heat generated = 1008 J
Since the total heat generated by the combustion of compound z is 1008 J, we can calculate the heat of combustion using the formula:
Heat of combustion = Total heat generated / amount of compound burned
Heat of combustion = 1008 J / 0.06
Heat of combustion = 16800 J/mol
Therefore, the heat of combustion of compound z is 16800 J/mol.
