CaBr conducts electricity in the molten state but does not conduct as a solid. ionic dissolution equation.
Zn⁰ ----> Zn⁺² + 2e⁻ - oxidation
Hg⁺² + 2e⁻ ----> Hg⁰ - reduction
Zn loses 2 moles of electrons , and Hg gains 2 mole of electrons.
So, number of moles of electrons gained and lost during reaction is equal.
I don’t know if I am right but I think it is symbol for the first one and the second one is formula.
A. A pure chemical substance consisting of one type of atom
