The formula for aluminum fluoride is ![AlF_{3}](https://tex.z-dn.net/?f=AlF_%7B3%7D)
That means that there is 1 Aluminum and 3 fluorde ions in 1 molecule. The 3 does not effect the Aluminum at all.
The Answer is A
Polyatomic ions:
,
,
,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)
Monatomic ions:
,
, and ![Fe^{3+](https://tex.z-dn.net/?f=Fe%5E%7B3%2B)
<h3>Monoatomic vs Polyatomic Ions</h3>
In chemistry, monoatomic ions are ions that consist of only a single type of atom. They are usually positive or negatively charged and are otherwise known as simple ions. Examples include
,
, and ![Fe^{3+](https://tex.z-dn.net/?f=Fe%5E%7B3%2B)
Polyatomic ions, on the other hand, are ions that consist of more than one atom, unlike monoatomic ions. The two or more atoms are covalently bonded and the entire structure behaves like a single chemical entity in reactions. Polyatomic ions are otherwise known as molecular ions.
Examples of polyatomic ions are
,
,
,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)
Thus, from the diagram:
- Polyatomic ions:
,
,
,
,
, and ![OH^-](https://tex.z-dn.net/?f=OH%5E-)

Answer:
If you contact water with a gas at a certain temperature and (partial) pressure, the concentration of the gas in the water will reach an equilibrium ('saturation') according to Henry's law.
Explanation:
This means: if you increase the pressure (e.g. by keeping the vial closed), the CO2 concentration will increase. So it simply depends what concentration you need for your assay: 'CO2-saturated' water at low pressure or 'CO2-saturated' water at high pressure.
Answer:
<h2>14.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
![n = \frac{N}{L} \\](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7BN%7D%7BL%7D%20%5C%5C)
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
![n = \frac{8.46 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.053156](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B8.46%20%5Ctimes%20%20%7B10%7D%5E%7B24%7D%20%7D%7B6.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%20%20%5C%5C%20%20%3D%2014.053156)
We have the final answer as
<h3>14.05 moles</h3>
Hope this helps you
