Magnesium and I think its MG12 for the other part
Answer:
Explanation:
Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out. In the case of salt for example, sodium has a charge of positive one, and chloride has a charge of negative one. Together, they neutralize the compound.
Lithium atomic number = 3
Li atom has 3 protons,3 electrons.Then it has no charge.
So the charge of Li atom here is zero.
<u>Option b: 0 is the right answer.</u>
Answer:
Approximately under standard conditions.
Explanation:
Equation for the overall reaction:
.
Write down the ionic equation for this reaction:
.
The net ionic equation for this reaction would be:
.
In this reaction:
- Zinc loses electrons and was oxidized (at the anode): .
- Copper gains electrons and was reduced (at the cathode): .
Look up the standard potentials for each half-reaction on a table of standard reduction potentials.
Notice that is oxidation and is likely not on the table of standard reduction potentials. However, the reverse reaction, , is reduction and is likely on the table.
The reduction potential of would be , the opposite of the reverse reaction .
The standard potential of the overall reaction would be the sum of the standard potentials of the two half-reactions:
.
