    Fossil fuels are a non-renewable resource and they will eventually run out. Hydrogen is predicted by many as the fuel of the future. State two ways of making hydrogen on a large scale and write an equation to illustrate one of these reactions.

    Alcohols can be obtained by the reduction of aldehydes and ketones using hydrogen and a suitable catalyst. Name the catalyst used in these reduction reactions.

    Nickel catalyst I believe, could be wrong.

    Um ... shouldn't these be covered in your texts?

    Or are you just looking for someone to do your homework for you and save you opening the book? ;)

    I think its production of ammonia and steam reforming >> CH4+H20=CO+3H2. It should be in chapter 21 of organic chrmistry, after the octane number of fuels I think!

    Electrolysis of water as well. H2O>H2+halfO2
