Q.

The minimum amount of O2(g) consumed per gram of reactant is for the reaction:

(Given atomic mass : Fe = 56, O = 16, Mg = 24, P = 31, C = 12, H = 1)

  1. A

    2Mg(s) + O2(g) 2MgO(s)

  2. B

    4Fe(s) + 3O2(g) 2Fe2O3(s)

  3. C

    C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(I)

  4. D

    P4(s) + 5O2(g) P4O10(s)
