The cell notation for the voltaic cell that incorporates the redox reaction Mg(s) + Sn²⁺(aq) → Mg²⁺(aq) + Sn(s) is Mg(s)|Mg²⁺(aq)║Sn²⁺(aq)|Sn(s).
The cell notation for a voltaic cell is the following:
anode ║ cathode
The anode is where the oxidation reaction takes place and the cathode is where the reduction happens.
The given reaction is:
Mg(s) + Sn²⁺(aq) → Mg²⁺(aq) + Sn(s)
We can see that <u>magnesium </u>is <u>oxidizing</u> (it is losing electrons) and that <u>tin </u>is <u>reducing</u> (it is gaining electrons).
These two processes can be represented in the following half-reactions:
Oxidation: Mg(s) → Mg²⁺(aq)
Reduction: Sn²⁺(aq) → Sn(s)
Which in <u>cell notation</u> is:
Anode: Mg(s)|Mg²⁺(aq)
Cathode: Sn²⁺(aq)|Sn(s)
Hence, the <u>notation</u> for the <u>voltaic cell</u> is:
Mg(s)|Mg²⁺(aq)║Sn²⁺(aq)|Sn(s)
Therefore, the cell notation for the voltaic cell with the given reaction is Mg(s)|Mg²⁺(aq)║Sn²⁺(aq)|Sn(s).

Answer: A.) Each chlorine atom shares a pair of electrons with the sulfur atom. This would be the right answer
Explanation:
Answer:
Metals have one or two electrons in their outermost shell
C. 1-2
Explanation:
- Metals have low ionisation energy because they easily looses the outermost electrons
- They have only one- two electrons in the outer most shell.
- They loose these electron to form charged species called cation.
Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is a specie which accepts electrons and gets reduced in a chemical reaction.
In the given reaction,
Oxidation state of Al changes from 0 to +3, therefore, it is reducing agent. Whereas oxidation state of Br is changing from -2 to -3 this means Br is gaining electrons, therefore, it is an oxidizing agent.
Thus, we can conclude that the statement is the oxidizing agent because its oxidation number decreases.
Answer:
Single Replacement
Explanation:
Single Replacement reactions are A + BX = AX + B. It's easy to tell if somthing is a single replacement reaction by seeing if it is a lone element like Sodium or Calcium
