You have 16.0 g of some compound and you perform an experiment to remove all of the oxygen, 11.2 g of iron is left. What is the

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 $Fe_{2}O_3$

What is the state of the mantle

damaskus [11]

The mantle is mostly rich in iron and magnesium oxides and silicates. The mantle is usually divided into the Upper and Lower mantle separated by a transition zone that is smaller than the one that exists between the Inner and Outer core.

Some key things to remember when discussing states of Earth's structure are:
1. Temperatures are highest at depth and increase as you go towards the surface
2. Materials are thicker at depth, with high viscosity, due to increased pressure

Therefore, rocks in the lower mantle are at a high enough temperature that they become soft and are able to flow slowly.
