This is not a redox reaction. None of the species are reduced and none are oxidized.

<h3>What is redox reaction?</h3>

A chemical reaction known as an oxidation-reduction (redox) reaction includes the exchange of electrons between two substances. An oxidation-reduction reaction is any chemical process in which a molecule, atom, or ion experiences a change in its oxidation number as a result of gaining or losing an electron.

Redox reactions are those in which one chemical is reduced and another is oxidized. Here, oxygen is being introduced, which causes C to oxidize into CO, and oxygen is being removed, which causes ZnO to decrease to Zn. It is a redox reaction as a result.

Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number.

Determine the percent composition by mass of a 100g salt solution which contains 20g salt
prisoha [69]

Answer:

Mass of solution=100g

mass of salt=20g

so; mass of solute=80g

percentage composition =(mass of salt/total

mass) ×100

=  \frac{20}{100}  \times 100 \\  = 20\%

glad to help you

hope it helps

What would be the total volume of the new solution when it is changed from 0.2 M to 0.04 M?
34kurt
The question is incomplete.

You need two additional data:

1) the original volume
2) what solution you added to change the volume.

This is a molarity problem, so remember molarity definition and formula:

M = n / V in liters: number of moles per liter of solution

To give you the key to answer this kind of questions, supppose the original volumen was 1 ml and that you added only water (solvent).

The original solution was:

V= 1 ml
M = 0.2 M

Using the formula for molarity, M = n / V

n = M×V = 0.2 M × (1 / 10000)l = 0.0002 moles

For the final solution:

n = 0.0002 moles
M = 0.04

From M = n / V ⇒ V = n / M = 0.002 moles / 0.04 M = 0.05 l

Change to ml ⇒ 0.05 l × 1000 ml / l = 50 ml.  This would be the answer for the hypothetical problem that I assumed for you.

I hope this gives you all the cues you need to answer similar problems about molarity.

With the levels closest to the nucleus of
Dmitry_Shevchenko [17]

Answer:

The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. ... The electrons in the energy level farthest from the nucleus are called valence electrons. Atoms in the same column (group) in the periodic table have the same number of valence electrons.
