Which state of matter contains atoms that are completely ionized?

1 answer:

8 0

This is actually known as the fourth state of matter which is the<em> plasma</em>. The plasma is basically a hot ionized gas. It consists of equal number of protons and electrons. This can be obtained by subjecting a gas to a high energy, for example, a laser beam. The energy from the laser beam causes a rapid energy increase of the atoms, such that they become ionized.

In a hotel breakfast bar, you see an older woman sticking a fork into a toaster to remove a piece of toast. You warn her not to

Answer:

See explanation

Explanation:

You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!

Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.

Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.

Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.

Also, in elements, there is a conduction band and a valence band. Electrons occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.

So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.

F2 + 2HCl + Cl2 + 2HF I need help what are the answers to these questions?

Anon25 [30]

In the given reaction fluorine is reduced and chlorine is oxidized.

<h3>What is oxidation and reduction?</h3>

Oxidation is a process in which addition of oxygen or removal of hydrogen and electron takes place, while reduction is a process in which addition of hydrogen & electrons or removal of oxygen takes place.

Given chemical reaction is:

F₂ + 2HCl → Cl₂ + 2HF

In the above reaction fluorine is reduced as it accepts an electron and increase in it its oxidation state takes from 0 to -1, which shows reduction.
In the reaction chlorine is oxidized as it losses an electron and decrease in its oxidation state takes from -1 to 0, which shows oxidation.
Oxidation half reaction is:

F₂ + 2e⁻ → 2F⁻

Reduction half reaction is:

2Cl⁻ → Cl₂ + 2e⁻

Hence, fluorine is reduced and chlorine is oxidized in the given reaction.
