Write a balanced half-reaction for the reduction of gaseous oxygen to aqueous hydrogen peroxide in basic aqueous solution. Be su
Vesna [10]

Answer:

Balanced half-reaction: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Explanation:

Balanced half-reaction for the reduction of gaseous oxygen to aqueous hydrogen peroxide in basic solution should be written in the following step-by-step manner:

Half-reaction: O_{2}(g)\rightarrow H_{2}O_{2}(aq.)

Balance H and O in basic medium: O_{2}(g)+2H_{2}O(l)\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Balance charge: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Balanced half-reaction: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

determine the number of possible product for treating the following compound with NBS adligh(Hv). Countsterioisomers as a single
lord [1]

Two distinct products of the reaction could emerge, both of which might turn out to be stereoisomers of one another.

<h3>What is the number of products?</h3>

We now understand that the chemical as demonstrated can experience monobromination, and the resulting compound is the same compound. However, due to the reaction's nature, we would have two steroisomers.

Given the reaction's process, we are aware that there are two distinct reaction products that may turn out to be stereoisomers of one another.
