The correct answer is A. why a balloon deflates when the air around it cools

Explanation:

According to Charles' law, in gases the temperature and volume are related, in this way the volume of a gas increases if these are heated or if the temperature rises and in the same way the volume of a gas decreases as the temperature falls. This law explains "why a balloon deflates when the air around it cools" because this shows the gas in the balloon reduces its volume and therefore deflates when the temperature decreases, which shows the relationship between temperature and volume described in Charles' law.

oksian1 [2.3K]

The empirical formula of this compound is equal to $Fe_{2}O_3$ .

<h3>Empirical formula</h3>

To calculate the empirical formula of a compound, it is necessary to know the number of moles present.

Therefore, we will use the molar mass of iron and oxygen to find the amount of moles, so that:

$MM_O = 16g/mol\\MM_Fe = 55.8g/mol$

$MM = \frac{m}{mol}$

Oxygen

$16 = \frac{4.8}{mol}$

$mol = 0.3$

Iron

$55.8 = \frac{11.2}{mol}$

$mol = 0.2$

Finally, as the empirical formula is composed of integers numbers of moles, just multiply the values by the smallest common factor to transform into an integer, so that:

O => $0.3 \times 10 = 3moles$

Fe => $0.2 \times 10 = 2moles$

So, the empirical formula of this compound is equal to $Fe_{2}O_3$

How does distillation work.

Usimov [2.4K]

Answer:

Distillation is an important commercial process that is used in the purification of a large variety of materials. However, before we begin a discussion of distillation, it would probably be beneficial to define the terms that describe the process and related properties. ... Elevation of the boiling point with an increase in external pressure, while important in cooking and sterilizing food or utensils, is less important in distillation.
