In an experiment 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.

If 'm' g of fuel is completely burned and that heat energy is supplied to 'M' g of water to raise its temperature by Deltat^(@)C then arrange the following steps in a sequences to calculate the calorific value of the fuel (a) Determine the heat energy absorbed by water (b) Determine the calorific value by dividing heat energy produced with mass of the fuel (c ) Note down the amss of water specific heat capacity and change in temperature of water (d) Heat energy absorbed by water is equal to heat given by the guel after complete combustion

When 14 grams of ethene is completely burnt in oxygen, the heat evolved is 705 kJ. What is the heat of combustion (in kJ mol^(-1) ) of ethene ?
