Um.......How the hell are you suposed to find that?
The number of units of aluminum chloride (AlCl₃) that can be produced from 30 atoms of aluminum (Al) is 30 units
The balanced equation for the reaction is given below:
2Al + 3Cl₂ — > 2AlCl₃
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
With the above information, we can determine the number of units of AlCl₃ that can be produced by the reaction of 30 atoms of Al. This can be obtained as follow:
From the balanced equation above,
2 atoms of Al reacted to produce 2 units of AlCl₃.
Therefore,
30 atoms of Al will also react to produce 30 units of AlCl₃.
Thus, 30 units of AlCl₃ were obtained from the reaction.

The radius of the football would be 748299320 times bigger than that of one atom of fluorine.
<h3>Atomic radius of fluorine</h3>
The atomic radius of a fluorine atom is 147 picometers or 147 x m.
The radius ratio of a football with 11 cm radius and that of one atom of fluorine can be calculated as:
11 x /147 x
= 748299320
Thus, the radius of the football would be 748299320 times bigger than that of one atom of fluorine.

The chemical formula for ammonia is NH3. So first, you need to find the molar mass of ammonia (how many grams in one mole).
N=14g
H3=3g
So one mole of NH3 is 17 grams, you can divide 82.9 grams by 17 grams to find the number of molecules. The answer should be 4.876 moles (molecules) of ammonia. Hope this helps!
