The answer is C the movement of skills from one experience to another

Answer:

C

Explanation:

Transferable skills are an important component of the skills you need for a job. These are the skills you obtain from one experience and later use in another. You can gain these skills from various life experiences, work experiences, or projects that you have worked on. You gain transferable skills at school, at work, while doing voluntary work, or from a hobby or sports. These skills include punctuality, teamwork, and leadership.

Answers

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.



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.

If you knew the number of valence electrons in a nonmetal atom how would you determine the valence of the element

Answers

Basically, nitrogen has 5 valence electrons and it needs 3 more valence electrons to be able to obtain a complete octet. Thus, after the bond, N2 contains 8 valence electrons.
N2 is a chemical formula of Nitrogen gas. Nitrogen is called N2 and not N because it needs to be combined with other nitrogen element in order to complete its octet. This combination of 2 Nitrogen atoms is called triple bond with a symbol of ( : N ≡ N: )
