    Question:1

    Which of the following is not a physical change?
    (a) Boiling of water to give water vapour
    (b) Melting of ice to give water
    (c) Dissolution of salt in water
    (d) Combustion of Liquefied Petroleum Gas (LPG)

    Answer: (d)

    (a) Boiling of water to give water vapour – Change in state – Physical change
    (b) Melting of ice to give water - Change in state – Physical change
    (c) Dissolution of salt in water - When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. This is considered as a physical change.
    (d) LPG is liquefied petroleum gas, which reacts with oxygen to form new products as carbon dioxide (CO_{2}) and water (H_{2}O). Therefore, combustion of LPG is a chemical change.
    Combustion is always a chemical change because it is irreversible.

    Answer: (d)

    Storing of oxygen gas under pressure in a gas cylinder – does not involve chemical reactions
    Liquefaction of air - Air is liquefied by the Linde process, in which air is alternately compressed, cooled, and expanded, each expansion results in a considerable reduction in temperature. With the lower temperature the molecules move more slowly and occupy less space, so the air changes phase to become liquid. Hence it does not involve chemical reactions
    Keeping petrol in a china dish in the open – does not involve chemical reactions
    When copper is heated in the presence of air in a very high temperature, a chemical reaction takes place.
    2Cu + O_2 \rightarrow 2CuO

    You are provided with two containers made up of copper and aluminium. You are also provided with solutions of dilute HCl, dilute HNO_3, ZnCl_2 \;and \;H_2O. In which of the above containers these solutions can be kept?

    Answer:

    Dilute HCl
    Copper does not react with dilute HCl, so it can be stored in a copper vessel
    Dilute HNO_3
    3Cu(s)+8HNO_{3}(aq)\rightarrow 3Cu(NO_{3})_{2}(aq)+2NO(g)+4H_{2}O(l)
    Cannot be stored in copper vessel as above chemical reaction takes place.
    Hence stored in aluminium vessel
    ZnCl_2
    No reaction takes place because copper is less active metal than zinc and can't displace it from ZnCl_2 solution.
    Hence stored in copper vessel
    H_2O
    No reaction occurs between copper and water so water can be stored in copper vessel.
