Answer 4

unit is (C)oulombs

Question 5

time (t)

Answer 5

unit (s)econds

Question 6

current (I)

Answer 6

unit A

Question 7

equation

Answer 7

C= A × s
or
Q= I x t

Question 8

steps to determine the mass of a Mol of an ion (eg. mg) produced at a particular quantity of electricity

Answer 8

1. calculate quantity of electricity
2. write reaction at the electrode
3. get the ratio of mole of electrons to mole of ion
4. calculate one C per mol
5. then the C used in the reaction
6. calculate the mass of mg produced in the equation
