    Coal plays a crucial role in India’s economic and industrial growth.

    • Energy source: Nearly 70% of India’s electricity is generated from coal-based thermal power plants.
    • Industrial use: Coal is essential in steel, cement, and chemical industries as a raw material and energy source.
    • Employment and revenue: Coal mining provides jobs and contributes significantly to government income through taxes and royalties.
    • Transport and infrastructure: It supports railway freight and industrial logistics.

  5. Answer: Aluminium oxide and zinc oxide are amphoteric oxides; they react with dilute hydrochloric acid to form corresponding chlorides and with aqueous sodium hydroxide to form soluble aluminates or zincates. Calcium oxide is a basic oxide; it reacts with dilute hydrochloric acid but not with sodiumRead more

    Answer: Aluminium oxide and zinc oxide are amphoteric oxides; they react with dilute hydrochloric acid to form corresponding chlorides and with aqueous sodium hydroxide to form soluble aluminates or zincates. Calcium oxide is a basic oxide; it reacts with dilute hydrochloric acid but not with sodium hydroxide. Sulphur dioxide is an acidic oxide; it does not react with hydrochloric acid but reacts with bases like sodium hydroxide to give sulphites/bisulphites, so statement IV is incorrect here.
