Part d based on your answer to part c, how many bonding electrons and lone pair electrons (nonbonding electrons) are there in th

elena55 [62]

The Lewis Structure of HCN is shown below,

Number of Bonding Electrons:
In HCN Hydrogen is bonded to Carbon through single bond and Nitrogen is bonded to Carbon through Triple Bond. Single bond is formed by two bonding electrons, while, triple bond is formed by six bonding electrons, Hence,

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons:
In HCN there is only one lone pair of electron present on Nitrogen atom which is not taking part in bonding. Hence,
Number of Non-Bonding Electrons = 2

Result:

Number of Bonding Electrons = 8

Number of Non-Bonding Electrons = 2

The iron content of foods can be determined by dissolving them in acid (forming Fe3+), reducing the iron(III) to iron(II), and t

____ [38]

Answer:

Oxidation half-reaction:

Fe²⁺(aq) → Fe³⁺(aq) + 1e⁻

Reduction half-reaction:

Ce⁴⁺(aq) + 1e⁻ → Ce³⁺(aq)

Explanation:

The reaction that takes place is:

Fe²⁺(aq) + Ce⁴⁺(aq) → Fe³⁺(aq) + Ce³⁺(aq)

The oxidation half-reaction is:

Fe²⁺(aq) → Fe³⁺(aq) + 1e⁻

It is an oxidation because the oxidation state of Fe increases from 2+ to 3+.

The reduction half-reaction is:

Ce⁴⁺(aq) + 1e⁻ → Ce³⁺(aq)

It is a reduction because the oxidation state of Ce decreases from 4+ to 3+.
