I need to get these into chemical equations please help I need to turn them in today !

hydrogen sulfide + oxygen =water +sulfer dioxide

zinc+hydrochloric acid = zinc chloride +hydrogen

calcium +water =calcium hydroxide +hydrogen

aluminum +lead II nitrate = aluminum nitrate +lead

potassium carbonate + barium chloride =potassium chloride + barium carbonate

iron+oxygen = iron III oxide

silver acetate + potassiumchromate = silver chromate + potassium acetate

lead II sulfide + oxygen =lead IIoxide +sulfer dioxide

carbon disulfide + oxygen = carbon dioxide + sulfer dioxide

aluminum chloride + sulfuric acid = aluminum sulfate + hydrogen chloride

I guess that it's a little too late, but you basically need to replace the names of the substances by their chemical symbols. For that, you need to know the valencies of the substances you are working with.

Can you post the formulae of the substances?
