Both have equal reactivity Lead Z None of the above None 5. Which of the following is the correct arrangement of the given metals in ascending order of their reactivity?Zinc, Iron, Magnesium, Sodium Sodium > Zinc > Magnesium > Iron Zinc > Iron > Magnesium > Sodium Sodium > Magnesium > Zinc > Iron Sodium > Magnesium > Iron > Zinc None 6. 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 + 2Ba(OH) → 2BaCl2 + 2HOH + O2 HCl + Ba(OH)2 → BaCl2 + 2HOH 2HCl + Ba(OH)2 → BaCl2 + 2HOH 2HCl + Ba(OH)2 → BaH2 + 2HCl + O2 None 7. 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 ? 8. 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 is covalent in nature and conducts electricity. Salt solution contains ions which makes it conductive and allows the electricity 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 has a low melting point which allows the current to flow through it. None 9. Which of the following pairs will give displacement reactions? FeSO4 solution and silver metal MgCl2 solution and aluminium metal NaCl solution and copper metal AgNO3 solution and copper metal None 10. Which of the following oxide(s) of iron would be obtained on prolonged reaction of iron with steam ? 11. Soda Acid for extinguisher contains 12. A student studying the chemical properties of metals finds incomplete chemical reactions in his book, as shown below:MgO + HNO3 →Which option completes the reaction? MgO + HNO3 → Mg(NO3)2 + H2O MgO + HNO3 → Mg + NO2 + O2 MgO + HNO3 → Mg(OH)2 + 2NO2 MgO + HNO3 → Mg3N2 + 4H2O None 13. Electrolysis is used for oxides of highly reactive metals that are above: Mercury iron Antimony Aluminum None 14. 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. None 15. Choose one metal and one non-metal in liquid state at room temperature. Aluminum, Nitrogen Lead, Oxygen Iron, Chlorine Mercury, Bromine None 16. Polymer used in making floor tiles is 17.
