Question

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

Answer 1

Balanced equation for the reaction taken place :

$H_2\left(g\right)+CuO\left(s\right)⟶Cu\left(s\right)+H_{2}O\left(g\right)$

Answers :

( i ) elements – $H_{2}andCu$

( ii ) compounds – $H_{2}OandCuO$

( iii ) reactants – $H_{2}andCuO$

( iv) products – $H_{2}OandCu$

( v ) metal - Cu

(vi ) non metal – $H_2$
