Refer to the periodic table given in your book and now answer the following questions:
a. Select the possible non metals that can show disproportionation reaction.
b. Select three metals that can show disproportionation reaction.

Explanation

The nonmetals are: `P_(4), Cl_(2)` and `S_(8)`.
i. `P_(4)(s)+3 overset(Θ)(O)H(aq)+3H_(2)O(l) rarr PH_(3)(g)+3H_(2)PO_(2)^(Θ)(aq)`
ii. `Cl_(2)(aq)+2 overset(Θ)(O)H(aq) rarr Cl^(Θ)(aq)+ClO^(Θ)(aq)+H_(2)O(l)`
iii. `S_(8)(s)+12overset(Θ)(O)H rarr 4S^(2-)(aq)+2S_(2)O_(3)^(2-)(aq)+6H_(2)O(l)`
b. The metal are `Cu^(o+), Ga^(o+), In^(o+)`, etc.
`2Cu^(o+)(aq) rarr Cu^(2+)(aq)+Cu(s)`
`3Ga^(o+)(aq) rarr Ga^(3+)(aq)+2Ga(s)`
`3In^(o+)(aq) rarr In^(3+)(aq)+2In(s)`
