Sample questions
-
1.The following reaction occurs when sulphur reacts with concentrated nitric acid: S + 6HNO₃ → H₂SO₄ + 2H₂O + 6NO₂. Which of the following correctly identifies the products formed in this balanced chemical equation?
- A.Sulphuric acid, water, and nitrogen dioxide
- B.Sulphurous acid, water, and nitrogen monoxide
- C.Sulphur dioxide, water, and nitrogen dioxide
- D.Sulphuric acid, hydrogen, and nitrogen gas
-
2.Which of the following correctly describes the precipitation method for preparing insoluble salts and provides a valid example?
- A.Insoluble salts are prepared by reacting two soluble salts or a soluble salt with an acid, forming a precipitate. Example: BaSO₄ from BaCl₂ and H₂SO₄.
- B.Insoluble salts are formed by heating a single soluble salt until it decomposes. Example: CaCO₃ from heating Ca(HCO₃)₂.
- C.Insoluble salts are obtained by evaporating a solution of a soluble salt. Example: NaCl from seawater evaporation.
- D.Insoluble salts are prepared by reacting a metal with an acid. Example: ZnSO₄ from Zn and H₂SO₄.
