Q a. Ahmed worked on his crops of wheat and maize to produce a better-quality crop (which gives a more yield). In detail, write down how he altered his crop into a better yielding crop.

b. What is the name of the process that Ahmed used to breed his new better-quality wheat and maize.

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
