Alright Noh — let's do this.

b) i) During cracking, long-chain alkanes are converted to shorter chain alkanes and alkenes. ii) Thermal decomposition is the breakdown of a compound into simpler substances by heating it.

c) • Refinery gas $\rightarrow$ bottled gas • Naphtha $\rightarrow$ making chemicals • Lubricating fraction $\rightarrow$ waxes and polishes • Kerosene $\rightarrow$ jet fuel
