Question

(e)
Write a balanced chemical equation for each of the following:
(i) Action of heat on calcium bicarbonate
(ii) Action of dilute sulphuric acid on sodium carbonate
(iii) Action of hot water on heated magnesium
(iv) Action of dilute hydrochloric acid on tron.
(v) Action of sodium hydroxide solution on aluminium.​

Answer 1

Answer:

• caHco3 when heated it give calcium oxide and carbon dioxide I know that much I hope its helpful for u

Answer 2

The desired chemical equations written in form of word are as follows :

• Two moles of calcium bicarbonate on  heating produces two moles of calcium oxide, two moles of carbon dioxide and one mole of water.
• One mole each of sodium carbonate and dilute sulfuric acid reacts to produce one mole each of sodium sulfate,water and carbon dioxide.
• One mole each of magnesium and water reacts to form one mole of magnesium oxide and one mole of hydrogen gas.
• One mole of iron reacts with two moles of dilute hydrochloric acid to form one mole each of ferrous chloride and hydrogen gas.
• Two moles each of sodium hydroxide , aluminium  and water reacts to produce two moles of sodium aluminate(NaAlO2) and three moles of hydrogen gas.
