Aluminum, Nitrogen Lead, Oxygen Iron, Chlorine Mercury, Bromine None 10. Match the following.PropertyMetala. Hardest metal1.Silver b. Reddish-brown metal2.Mercuryc.Best conductor of electricity3.Osmiumd.Liquid metal4.Copper a−3,b−4,c−1,d−2 a−4,b−2,c−3,d−4 a−4,b−3,c−2,d−1 a−2,b−1,c−4,d−3 None 11. Alloys are homogeneous mixtures of a metal with a metal or non-metal. Which among the following alloys contain non-metal as one of its constituents ? 12. Polymer used in making floor tiles is 13. A student makes an electric circuit using an LED, a battery and connecting wires to test the conductivity of distilled water. The student notices that the LED does not glow. He replaces the distilled water with a salt solution and observes that the LED glows. How does the salt solution help the LED to glow? Salt solution has a low melting point which allows the current to flow through it. Salt solution has a high boiling point which allows the flow of current in the circuit without getting hot. Salt solution contains ions which makes it conductive and allows the electricity to flow through it. Salt solution is covalent in nature and conducts electricity. None 14. Aqua regia is a freshly prepared mixture of concentrated HNO3 and concentrated HCl in the ratio of: 3:2, respectively 2:3, respectively 1:3, respectively 3:1, respectively None 15. Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam ? 16. The chemical reaction between a piece of copper and nitric acid is given by the chemical equations,Cu + HNO3 Cu(NO3)2 + H2H2 + HNO3 H2O + NO2What can be inferred from the chemical equation? Copper causes the oxidation of HNO3 to form NO2. Hydrogen gas gets oxidized by HNO3 to form water. Nitrate reacts with hydrogen to form NO2 and H2O. gas reacts with oxygen in the air to form water. None 17. Metals in the middle of the activity series are generally present as _______ in nature. oxides and chlorides sulphides and carbonates all of the above carbonates and halides None 18. Mark the correct option:a) Pure metal from the electrolyte is deposited at the anode.b) The soluble impurities go into the solution.c) Insoluble impurities are known as anode mud A,c B,c A,b All the statement is correct None 19.
