Hey its me again
for the first one - its because chromate ions are negative and are yellow so they will accumulate at the positive electrode and turn the solution from green to yellow

For number 2 it should be water
For number 3 positive cu2+ ions travel to negative electrode (electrostatic attraction) and accept electrons - reduction - so they turn into copper metal and deposit around the electrode

for the final one - potassium/potassium ions go to the negative electrode and iodine/iodide ions go to the positive electrode
