‘Propagas’ is used in some central heating systems where natural gas is not available. It burns according to the following equation:

a. What are the chemical names for ‘propagas’ and natural gas?

b. Would you expect the heat generated per mole of ‘propagas’ burned to be greater than that for natural gas? Explain your answer.

c. What is ‘propagas’ obtained from?

d. Calculate:

(i) the mass of ‘propagas’ required to produce 5550 kJ of energy

(ii) the heat energy produced by burning 0.5 mole of ‘propagas’

(iii) the heat energy produced by burning 11 g of ‘propagas’

(iv) the heat energy produced by burning 2000 dm³ of ‘propagas’. (Ar: H = 1; C = 12; O = 16. One mole of any gas occupies 24 dm³ at room temperature and pressure.)
