Answer

a) $Fe_{2}O_{3} +3Mg → 3MgO + 2Fe$ ferric oxide + magnesium → magnesium oxide + iron b) $AlCl_{3} + 3NaOH → Al(OH)_{3} + 3NaCl$ Aluminum chloride + sodium hydroxide → Aluminum hydroxide + sodium chloride c) $2NaNO_{3} + H_{2}SO_{4} → Na_{2}SO_{4} + 2HNO_{3}$ sodium nitrate + sulfuric acid → sodium sulfate + nitric acid d) $NiCO_{3} + 2HNO_{3} → Ni(NO)_{3} + CO_{2} + H_{2}O$ nickel carbonate + nitric acid → nickel nitrate + water

Work Step by Step

a) $Fe_{2}O_{3} +3Mg → 3MgO + 2Fe$ ferric oxide + magnesium → magnesium oxide + iron one moles of ferric oxide reacts with three moles of magnesium to form three moles of magnesium oxide and two moles of iron in free state. b) $AlCl_{3} + 3NaOH → Al(OH)_{3} + 3NaCl$ Aluminium chloride + sodium hydroxide → Aluminium hydroxide + sodium chloride one mole of aluminium chloride reacts with three moles of sodium hydroxide to form one mole of aluminium hydroxide and three moles of sodium chloride. c) $2NaNO_{3} + H_{2}SO_{4} → Na_{2}SO_{4} + 2HNO_{3}$ sodium nitrate + sulfuric acid → sodium sulfate + nitric acid d) $NiCO_{3} + 2HNO_{3} → Ni(NO)_{3} + CO_{2} + H_{2}O$ nickel carbonate + nitric acid → nickel nitrate + water
