Explanation:
number of atoms = moles × avegadro number
so 5.55 × 10^2 = moles × 6.023 × 10^23
moles = 5.55 × 10^2 ÷ 6.023 × 10^23 = 9.214×10−22 moles
Answer:
so the earth has an atmosphere, which holds in all the oxygen, it has gravity, and it has the green house effect, causing the earth's warmth to stay in it's atmosphere
In scientific notation it would be 3.2
<span>oxidation, because oxygen is combining with the banana peel, and the peel is reacting with the air.</span>
The pair of elements which is most apt to form a molecular compound with each other would be sulfur and fluorine. In general, a nonmetal and a gas is most likely to form a molecular compound. Considering two metal molecules, most likely these metal atoms would not form a molecule since they are both positive when in ionic form and tends to donate electrons to another atom. For a situation where you have a nonmetal and a metal atom, it would not still be possible to form a molecular atoms since they are likely to form ionic bonds resulting to an ionic compound.<span />
