25.0g of Fe2O3. 2(55.8)g+3(16.0)g=159.9g. 2(55.8)g/159.6g•100%= 69.9%. 69.9%/100%•25.0g=17.5g of iron recovered

<u>Answer:</u> The mass of iron recovered is 17.5 grams

<u>Explanation:</u>

We are given a chemical compound having chemical formula of Fe_2O_3

We know that:

Molar mass of iron (III) oxide = 159.7 g/mol

Mass of iron = 55.8 g/mol

We are given:

Mass of iron (III) oxide = 25 g

To calculate the mass of iron recovered in given amount of iron (III) oxide, we use unitary method:

From 159.7 grams of iron (III) oxide, mass of iron recovered is (2\times 55.8)g

So, from 25 grams of iron (III) oxide, mass of iron recovered will be \frac{(2\times 55.8)}{159.7}\times 25=17.5g

Hence, the mass of iron recovered is 17.5 grams

The picture shows two containers filled with a gas.
Irina18 [472]

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

<h3>What is temperature?</h3>

The term temperature refers to a measure of the average kinetic energy of the molecules of  body. This means that molecules that are at high temperature tend to move faster than the molecules that are at low temperature.

As such, the higher temperature of the molecules of the gas in B shows that the molecules in B are faster than those in A thus the correct statement is; "the average kinetic energy of the gas particles is greater in container B because it has a higher temperature."

Missing parts;

The picture shows two containers filled with a gas.

Two equally sized containers are shown with tight lids and each container has a thermometer. The container on the le is labeled A and the one on the right is labeled B. The thermometer inside container B shows a higher temperature than the thermometer inside container A.

Which statement is correct?

The average kinetic energy of the gas particles is greater in container A because it has a lower temperature.

The average kinetic energy of the gas particles is greater in container B because it has a higher temperature.

The gas particles in both containers have the same average kinetic energy because t have the same volume.

The gas particles in both containers have the same average kinetic energy because t have equal number of particles.
