The main chemical in the atmosphere of Venus is carbon dioxide. How does this compare with the atmosphere of Earth? A carbon dioxide is not found in the atmosphere of earth
B carbon dioxide makes up a small part of the atmosphere of earth
C carbon dioxide is the main chemical in the atmosphere of earth
D carbon dioxide is found in the atmosphere of earth only near volcanoes

B. Carbon dioxide makes up a small part of the atmosphere of earth

Explanation:

When you look at the air that you breathe, you will say, that you breathe Oxygen, but actually, you breathe 71% nitrogen, then 28% oxygen, then 1% of many different gases like Argon, and Carbon Dioxide. That 1% is very less compared to 100%, so that's why, hence, your answer is that carbon dioxide makes up a small part of the atmosphere of Earth.

B

Explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
