$Al$ is a reducing agent, $Cr _2O _3$ is an oxidizing agent.

<h3>What is an oxidizing agent?</h3>

An oxidizing agent is a substance that causes oxidation by accepting electrons.

Al is a reducing agent, $Cr _2O _3$ is an oxidizing agent.

Hence, option C is correct.

The balls are not perfectly elastic, but the main reason is probably air.
Explanation:
When 2 adjacent balls have any distance between them, there is air in the space. When the moving neighbor comes at a stationary ball the moving ball has to push the air out of the way.

Express the concentration of a 0.0320 M aqueous solution of fluoride, F−, in mass percentage and in parts per million (ppm). Ass

denis23 [38]

Answer:

607 ppm

Explanation:

In this case we can start with the ppm formula:

$ppm=\frac{mg~of~solute}{Litters~of~solution}$

If we have a solution of 0.0320 M, we can say that in 1 L we have 0.032 mol of $F^-$ , because the molarity formula is:

$M=\frac{mol}{L}$

In other words:

$0.0320~M=\frac{mol}{1~L}$

$mol=0.032~M*1~L=0.032~mol$

$1~L~of~Solution=0.0320~mol~of~solute$

If we use the atomic mass of $F$ (19 g/mol) we can convert from mol to g:

$0.0320~mol~F^-\frac{19~g~F^-}{1~mol~F^-}~=~0.607~g$

Now we can convert from g to mg (1 g= 1000 mg), so:

$0.607~g\frac{1000~mg}{1~g}=607~mg$

Finally we can divide by 1 L to find the ppm:

$ppm=\frac{607~mg}{1~L}=~607~ppm$

We will have a concentration of 607 ppm.

I hope it helps!

1. write a sentence that describes how the food changes in the stomach.

Advocard [28]

Explanation:

This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
