Explanation:
For what I can see, is missing the concentration of [Ag+] in the half-cell. To calculate it:
Niquel half-cell
Oxidation reaction:
Assuming T=298 K / R=8.314 J/mol K / F=96500 C
Silver half-cell
Reduction reaction:
Assuming T=298 K / R=8.314 J/mol K / F=96500 C
Do you mean rounding if u do then :
rounding to 1.s.f is 5g
rounding to 2.s.f is 5.4 g
rounding to 3.s.f is 5.43g
The maximum number is 10 electrons
1. To make steel
2. It's salts are used to treat anaemia.
3. Pure iron is used in magnets.
4. It is used as a catalyst in the Haber Process which makes ammonia.
5. A very pure iron called wrought iron is used for ornamental gates or fences.
The correct one would be volume
