To calculate the calorific value of coal using bomb’s calorimeter, which of the following compound are formed after the bomb is removed from the calorimeter?

To calculate the calorific value of coal using bomb’s calorimeter, which of the following compound are formed after the bomb is removed from the calorimeter? Correct Answer H2SO4 and HNO3

Since the vapours of H2SO4 and HNO3 are formed during combustion of coal, that is why at last the amounts of H2SO4 and HNO3 are calculated to find the gross calorific value of the coal.
