Sample questions
-
1.Both brass and bronze contain copper as major constituents. Which of the following correctly identifies the other primary elements present in these alloys?
- A.Brass contains copper and zinc; bronze contains copper and tin.
- B.Brass contains copper and tin; bronze contains copper and zinc.
- C.Brass contains copper and lead; bronze contains copper and aluminum.

2.Which statement correctly describes the reaction of alkali metals with water, including the general equation?
- A.Alkali metals react violently with water to produce hydrogen gas and their hydroxides, represented by the equation: 2M + 2H₂O → 2MOH + H₂, where M is any alkali metal.
- B.Alkali metals react slowly with water to form metal oxides and hydrogen gas, following the equation: M + H₂O → MO + H₂.
- C.Alkali metals do not react with water but dissolve in acids to release hydrogen gas, with the equation: M + 2HCl → MCl₂ + H₂.
- D.Alkali metals react with water to produce oxygen gas and metal hydrides, represented by the equation: 4M + 2H₂O → 4MH + O₂.

3.In the refining of aluminium using Hoope's electrolytic process, which of the following correctly describes the role and arrangement of the layers in the electrolytic cell?
- A.The bottom layer is pure molten aluminium acting as the cathode, the middle layer is a mixture of fluorides acting as the electrolyte, and the top layer is impure aluminium acting as the anode.
- B.The bottom layer is impure molten aluminium with a carbon lining acting as the anode, the middle layer is a mixture of fluorides acting as the electrolyte, and the top layer is pure molten aluminium acting as the cathode.
- C.The bottom layer is a mixture of fluorides acting as the electrolyte, the middle layer is impure aluminium acting as the anode, and the top layer is pure aluminium acting as the cathode.
- D.The bottom layer is pure molten aluminium acting as the anode, the middle layer is impure aluminium acting as the electrolyte, and the top layer is a mixture of fluorides acting as the cathode.
