Salt reaction of Nickel Carbonate and Sulfuric Acid?

Don't you feel it is a tiny bit unethical to be asking for answers to an A-level essed practical in such a public manner? You should be ashamed of yourself. If you don't know the answer then you should just guess or, at the very least, try to figure it out for yourself. Anyone who gives you the answer to these questions is just cheating every other candidate who is taking the same exam.
