Answer:

gas

Explanation:

The sky is not a solid body, nor does it have all of the same the physical properties of a solid body. In terms of its behavior, physically a gas is much closer to a liquid than a solid. If you drop the temperature of the atmosphere quick enough and low enough it can become a solid.

Gas.
The sky is not solid, not liquid but of gas. It is also called the atmosphere, one of the important spheres on earth that influences the climate –temperature, humidity, precipitation, atmospheric pressure, and the biotic community as a whole. The atmosphere or the sky is composed of many layers and is responsible to protecting the living organisms of the earth against the deadly ultraviolet rays and other strong radiation coming from the sun.

A compound 21.20% nitrogen 6.06% hydrogen 24.30% sulfur and 48.45% oxygen. Write the empirical formula and name the compound?

egoroff_w [7]

Greetings!

<h3>To find the empirical formula you need the relative atomic mass of each element!</h3>

N = 14

H = 1

S = 32.1

<h3>You can simply change the percentages into full grams</h3>

N = 12.20

H = 6.06

S = 48.45

<h3>Then you use this to find the Number of moles = amount in grams / atomic mass</h3>

N = 12.20 ÷ 14 = 0.8714

H = 6.06 ÷ 1 = 6.06

S = 48.45 ÷ 32.1 = 1.541

<h3>Then divide each number of moles by the smallest value:</h3>

N = 0.8714 ÷ 0.8714 = 1

H = 6.06 ÷ 0.8714 = 6.9 ≈ 7

S = 1.541 ÷ 0.8714 = 1.76 ≈ 2

So that means that there are 1 Nitrogen, 7 hydrogen, and 2 sulfur. This means the empirical formula would be:

NH₇S₂

Answer:

See explanation below

Explanation:

In this case, let's see both molecules per separate:

In the case of SeO₂ the central atom would be the Se. The Se has oxidation states of 2+, and 4+. In this molecule it's working with the 4+, while oxygen is working with the 2- state. Now, how do we know that Se is working with that state?, simply, let's do an equation for it. We know that this molecule has a formal charge of 0, so:

Se = x

O = -2

x + (-2)*2 = 0

x - 4 = 0

x = +4.

Therefore, Selenium is working with +4 state, the only way to bond this molecule is with a covalent bond, and in the case of the oxygen will be with double bond. See picture below.

In the case of CO₂ happens something similar. Carbon is working with +4 state, so in order to stabilize the charges, it has to be bonded with double bonds with both oxygens. The picture below shows.
