Question

Half-reactions can be written to represent all

(1) double-replacement reactions
(2) neutralization reactions
(3) fission and fusion reactions
(4) oxidation and reduction reactions

Answer 1

Answer=4

oxidation and reduction reactions

Answer 2

Answer: Option (4) is the correct answer.

Step-by-step explanation:

Half reactions are the reactions that represent oxidation and reduction reactions through separate steps.

For example,
`2Na + Br_(2) \rightarrow 2Na^(+) + 2Br^(-)` the oxidation and reduction half-reaction will be as follows.

Oxidation half-reaction:
`2Na \rightarrow Na^(+) + 2e^(-)`

Reduction half-reaction:
`Br_(2) + 2e^(-) \rightarrow 2Br^(-)`

Thus, we can conclude that half-reactions can be written to represent all oxidation and reduction reactions.
