A.)What is the Product at the anode and cathode for the following?

1.)molten -Sodium Chloride

2.)aqueous-sodium chloride

3.)aqueous -copper (II) SULPHATE (CuSO4)

4.)PbBr2

5.)KCl

6.)AgNO3

7.)Calcium Chloride

8)Hydrochloric acid

9)Sulphuric acid( H2SO4)

B.)    State  half equation for each at the anode and cathode reaction for each.

How does loss and gain of electrons relate to the half  equations?

*when they say molten and aqueous what exactly are we doing to each equation.where do they get like e- and 4e- during an equation ,can u explain also for each step just explain how did they get it .like negative  and the electrons ect
