    Q1. A sample of Magnesium nitrate is heated strongly in a test tube. Which set of products is released during this thermal decomposition mechanism?

    • A) Oxygen and Nitrogen gas
    • B) Magnesium nitrite and Oxygen
    • C) Magnesium oxide, Nitrogen dioxide, and Oxygen
    • D) Magnesium nitride and Oxygen

    Answer: Magnesium oxide, Nitrogen dioxide, and Oxygen

    Explanation: Group IIA nitrates decompose into metal oxides and NO2; lithium nitrate is tempting as it behaves similarly despite being a Group IA metal.
