The heat of combustion of butane is `2880kJ" "mol^(-1)`. What is the heat liberated by buring 1 kg of butane in excess of oxygen supply?

The heat of combustion of methane is -880 KJ mol^(-1) . The quantity of heat liberated in the combustion of 3.2 g methane is

The heat of combustion ( kJ "mol"^(-1) ) is highest for

If the heat of combustion of pentane is 3507 kJ mol^(-1) then its calorific value will be ?

If the heat of combustion of pentane is 3507 kJ mol^(-1) then its calorific value will be ?

a. A cylinder of gas is assumed to contain 11.2 kg of butane. If a normal family needs 20000kJ of energy per day for cooking, how long will the cylinder last? Given that the heat of combustion of butane is 2658 kJ mol^(-1) . b. If the air supply of the burner is insufficient (i.e. you have a yellow instead of a blue flame), a portion of the gas escape without combustion. Assuming that 33% of the gas is wasted due to this inefficiency, how long would the cylinder last?
