  • Question 1
    3 / -1

    What are the products of the decomposition of limestone?

    Solution

    Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide.

  • Question 2
    3 / -1

    The halogen with the highest value of ionisation energy is

    Solution

    Fluorine has highest value of electro negativity. Hence it has highest ionization energy.

  • Question 3
    3 / -1

    Which of the following gases is evolved on heating ammonium dichromate?

    Solution

    Nitrogen gas is evolved as the following reaction takes place:

    (NH4)2 Cr2O7 Cr2O2 + N2 + 4H2O

  • Question 4
    3 / -1

    In the complexes [Fe(CN)6]3- and [Fe(C2O4)3]3-, the respective coordination numbers of Iron is

    Solution

    In both the complex the coordination of iron is 6 each.

  • Question 5
    3 / -1

    Metamerism is shown by

    Solution

    Metamerism is shown by the compounds containing different alkyl groups containing at least two carbon atoms each on either sides of the S, O or NH.

  • Question 6
    3 / -1

    0.833 mole of a carbohydrate with empirical formula CH2O, has 1g of hydrogen. Molecular formula of carbohydrate is

    Solution

  • Question 7
    3 / -1

    Among the following, the correct order of basicity is

    Solution

  • Question 8
    3 / -1

    What is the increasing order of the first ionisation enthalpies of the elements B, P, S and F?

    Solution

    The value of first ionization energy decreases on moving from top to bottom in a group and increases on moving from left to right across a period in the periodic table.

  • Question 9
    3 / -1

    When lead nitrate is heated, it gives

    Solution

    Lead nitrate when heated will decompose forming lead oxide, nitrogen oxide, and oxygen.

    Equation:

    2Pb(NO3)2 will give 2PbO + 4NO2 + O2
