What is the oxidation number of all elements in MnSO4?

1 answer:

6 0

The oxidation number of the elements should be equal to zero or the charge of the compound when summed together. In this case, the overall charge is zero. Oxygen has a charge of -2, a total of -8, S has a charge of -2 so Mg must have a +10.

aluminum has a density of 2.70 g/ml. calculate the mass (in grams) of a piece of aluminum having a volume of 250 ml .

Inga [223]

Per ml, aluminum has 2.7 grams of mass. So in 250 ml, there are (2.7)*(250) number of grams.

675 grams.

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 are the 4 different types of bonds and how are they formed?

miv72 [106K]

There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.

To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:

Covalent is followed by ionic, hydrogen, and van der Waals.
