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

When hydrogen is passed over copper oxide, copper and steam are formed.
The balanced equation for this reaction is: $H_{2} +CuO\ \rightarrow \ Cu\ +H_{2} O$

(i) Elements: Hydrogen (H2) and copper (Cu)

(ii) Compounds: copper oxide (CuO) and water (H2O)

(iii) Reactants: Hydrogen (H2) and copper oxide (CuO)

(iv) Products: copper (Cu) and water (H2O)

(v) Metal: copper (Cu)

(vi) Non-metal: Hydrogen (H2)
