Question

The standard enthalpy of combustion of formaldehyde
is ΔcH0= -571KJ. How much heat will be evolved in the
formation of 22g of CO2?

Answer 1

Answer:

this is answer

Explanation:

Heat of combustion of benzoic acid (C6H5COOH) at constant volume at 25°C is - 3233 kJ/mole. When 0.5 g of benzoic acid is burnt in bomb calorimeter, the temperature of calorimeter increased by 0.53°C. Now in the same bomb calorimeter 1g of C₂H6 burnt then temperature increased by 2.04C. AH for combustion of C₂H6 is
