By weight atmospheric air is approximately 23.15% oxygen and 76.85% nitrogen. What is the partial pressure of oxygen in the air
inna [77]

Answer:

Partial pressure of oxygen = 23.38 kpa (Approx)

Explanation:

Given:

Amount of oxygen = 23.15%

Amount of nitrogen = 76.85%

Pressure (missing) = 101 kpa

Find:

Partial pressure of oxygen

Computation:

Partial pressure of oxygen = [Amount of oxygen x Pressure]/100

Partial pressure of oxygen = [23.15% x 101]/100

Partial pressure of oxygen = 23.38 kpa (Approx)

Answer:

<u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form  a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)

Therefore, <u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.
