Answer:
See below
Explanation:
The equation shows Al / Cl = 2/3 or 3/2 Al = Cl
3/2(20) = 30 Cl atoms needed
The equation shows a one-to-one relationship between Al and AlCl3
produced so if you use 20 Al atoms you get 20 AlCl3 molecules
Answer and Explanation:
In Chemistry, the quantity or amount of a pure substance is given by:
- <em>mass</em><em> (in grams)</em>
- <em>Volume </em><em>(in millilitres or litres)</em>
- <em>Moles </em><em>(mol) </em>
Inter-conversion of units is allowed based on defined units and constituent of the substance.
I believe this explanation would be helpful and easy to follow.
Answer:
The parts of an atom cannot be directly observed.
Explanation:
An atom is the smallest indivisible particle of a substance that can take part in a chemical reaction.
Atoms are not observed with naked eyes because they are found in the realm of very small particles. It is impossible to observe the parts of an atom directly.
As a result of this, models suffice in explaining the parts of an atom. Hence the answer.
