Answer:
B) atom of Xenon
Explanation:
Xenon is already stable alone, because it has a complete octet, or 8 electrons. This graph is not an ion because it shows xenon is its default state, consisting of 8 electrons.
It is not a molecule because a molecule is a group of atoms, or a compound, what is shown is a singular atom.
156. Atomic mass if the number of protons and neutrons within an atom.
I would say a. at the equator to the poles or maybe c. cold air rising and warm air sinking.
I think the answer is Endothermic. Since the question says "absorbs," endo means to "go in" sort of and exo means to exit.
exo = exit
endo = enter

Sorry if I'm wrong, hope I helped. :)
If the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
<h3>What is volume?</h3>
Volume refers to the space occupied by an object. Gases do not have a specific volume, rather they take on the volume of the container. We must note that the volume of given mass of gas is directly proportional to the number of moles present.
Hence, if the number of moles decreases from 5 moles of gaseous reactants to 2 moles of gaseous product, the overall change in volume of the system is negative.
