Write the word equation and the balanced equations for the reactions when:
(a) dilute sulphuric acid reacts with zinc granules.
(b) dilute hydrochloric acid reacts with magnesium ribbon.
(c) dilute sulphuric acid reacts with aluminium powder.
(d) dilute hydrochloric acid reacts with iron filings.
(a) Word equation:
Zinc + Sulphuric add ➝ Zinc sulphate + Hydrogen
Balanced equation:
Zn(s) + H2SO4(dil.) ➝ ZnSO4(aq) + H2(g)
(b) Word equation:
Magnesium + Hydrochloric acid ➝ Magnesium chloride + Hydrogen
Balanced equation:
Mg(s) + 2HCl (dil.) ➝ MgCl2(aq) + H2(g)
(c) Word equation:
Aluminium + Sulphuric acid ➝ Aluminium sulphate + Hydrogen
Balanced equation:
2Al(s) + 3H2SO4(dil.) ➝ Al2(SO4)3(aq) + 3H2(g)
(d) Word equation:
Iron + Hydrochloric acid ➝ Iron chloride + Hydrogen
Balanced equation:
Fe(s) + 2HCl(dil.) ➝ FeCl2(aq) + H2(g)
