Q. What are the Formulas for: nichkel (III) sulfite silver bromide copper (II) bicarbonate nickel (II) selenide manganese (IV) carbonate lead (IV) nitride tin (II) hydroxide

A. Any time you see a Roman numeral inside parens after a transition metal, this gives you the charge of the cation. If you see the ending -ite or -ate, these are polyatomic ions that you must learn the rules for. If you see the ending -ide, this is simply the ion of the element itself (except for hydroxide, which is OH-), ie. bromide is the anion of bromine. When figuring out formulas from names, you must remember that charges must balance, ie + charges must = - charges Look at tin (II) hydroxide: tin symbol is Sn, the charge is +2 since Roman numeral 2, and hydroxide is OH- (I memorized this). In order to balance this, you need two OH- for each Sn: Sn(OH)2 Do this same process for silver bromide, nickel selenide, lead nitride sulfite… [cont.]

A. I think no-one has answered but this is something you should be able to have a go at. I'll start you off. Calcium is Ca, it has a +2 charge (group 2), oxide is O, it has a -2 charge. Calcium oxide is therefore CaO. Potassium is K, it has a +1 charge (group 1), sulphide is S, it has a -2 charge. Potassium sulphide is therefore K2S. and so on...
