When hydrogen is passed over copper oxide, copper and steam are formed. Write a balanced equation for this reaction and state which of the chemicals are:

(i) elements


(ii) compounds


(iii) reactants


(iv) products


(v) metals


(vi) non-metals

The balanced chemical reaction:

H2 + CuO Cu + H20


(i) H2 and Cu are elements in the reaction.


(ii) The compounds are CuO and H20


(iii) The reactants are H2 and CuO


(iv) The Products are Cu and H20


(v) Metal involved in reaction Cu


(vi) The Non-metal involved in reaction H2.
