(a) Construct an equation to show the cracking of dodecane to make ethene. (1) (iii) What is the colour change when bromine water reacts with ethene? Crude oil is a finite resource.

What is an equation for cracking of ethane to produce ethene and hydrogen? _ (1) (ii) Write an equation for the cracking of one molecule of dodecane into equal amounts of two different molecules each containing the same number of carbon atoms. When alkenes react with bromine water the colour changes from orange to _. Decane, a 10-carbon n-alkane and one of the highest vapor phase constituents of jet propellent-8 (), was selected to represent the semivolatile fraction for the initial development of a physiologically based pharmacokinetic (PBPK) model for JP-8.Rats were exposed to decane vapors at time-weighted average concentrations of 1200, 781, or 273 ppm in a 32-L Leach chamber for 4 hr.
