Electrons in an excited state are more likely to enter into chemical reactions.

Chemistry
1 answer:
guajiro [1.7K]3 years ago
3 0

Answer:

False

Explanation:

The electrons  are excited because:

1.- They posses more energy than the basal form, but this doesn´t mean that they can easily react, remember, the electrons are the outside part of an atom.

2.-  By the time, this electrons are loosing their energy, that mean that they return to the basal form.

____ [38]

Answer:

  • <em>Oxidation half-reaction</em>:

Fe²⁺(aq) →  Fe³⁺(aq) + 1e⁻

  • <em>Reduction half-reaction</em>:

Ce⁴⁺(aq) + 1e⁻ →  Ce³⁺(aq)

Explanation:

The reaction that takes place is:

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

The <em>oxidation half-reaction</em> is:

  • Fe²⁺(aq) →  Fe³⁺(aq) + 1e⁻

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

The <em>reduction half-reaction</em> is:

  • Ce⁴⁺(aq) + 1e⁻ →  Ce³⁺(aq)

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

adell [148]

Answer:

B.  Cl.

Explanation:

These are Group  7 elements whose reactivity reduces as you go down the group. Chlorine  has a smaller atoms than the rest and has a stronger  tendency to grab an electron in its valency shell. This is because its nucleus is closer to the outer electrons than the other elements.
