Answer:
a) Hydrocarbons contain...... and carbon only.
Hydrogen

b)When you burn Hydrocarbons, ...... make carbon dioxide and water.
the reaction will

c)...is a hydrocarbon used as a fuel in lorries.
Diesel fuel. (That's what we call it in the USA. I don't know if you still call it "petrol.")

d)The.....between petrol and oxygen gives out lots of heat and energy.
reaction

e)When a substance burns it joins with .. oxygen from the air.
gaseous

f)Mathane+oxygen---->...
Carbon dioxide + water

g)Methane (natural gas) burns to make water and carbon dioxide which escapes into the .....
atmosphere

h)....=oxygen----->rubid... oxide
Huh?

i)When wax .... it makes carbon dioxide and water
burns in air

j)Hydrocarbons contain hydrogen and carbon...
(period)

k)....is a gas in the air which does not take part in burning reactions.
Argon.
(Your teacher probably wants you to say nitrogen -- but in some burning situations, oxides of nitrogen are produced).
K - Argon.
