Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam ? 4. The electronic configuration of three elements X, Y and Z are as follows: X = 2, 4 Y = 2, 7 Z = 2,1 Which two elements will combine to form an ionic compound and write the correct formula, XZ3 Y2Z ZY X2Y None 5. Polymer used in making floor tiles is 6. 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 high boiling point which allows the flow of current in the circuit without getting hot. Salt solution has a low melting point which allows the current to flow through it. Salt solution is covalent in nature and conducts electricity. Salt solution contains ions which makes it conductive and allows the electricity to flow through it. None 7. 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 All the statement is correct A,c B,c A,b None 8. In a solution of lead acetate, a strip of metal Z was dipped. After some time, lead from the solution was deposited at the metal strip. Which is more reactive? Z Lead Both have equal reactivity None of the above None 9. When hydrochloric acid is added to barium hydroxide, a white-coloured compound is formed. Which of the following option gives the complete chemical reaction? HCl + Ba(OH)2 → BaCl2 + 2HOH 2HCl + Ba(OH)2 → BaH2 + 2HCl + O2 2HCl + Ba(OH)2 → BaCl2 + 2HOH HCl + 2Ba(OH) → 2BaCl2 + 2HOH + O2 None 10. Ordinary glass is a mixture of 11. 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. gas reacts with oxygen in the air to form water. Hydrogen gas gets oxidized by HNO3 to form water. Nitrate reacts with hydrogen to form NO2 and H2O.
