I think it was the rate of reaction

What question had the answer "Electrolysis" ? The only question that I can remember that spoke about how metals are extracted was in section 1 MC.

Yes

You know the question with the graph and you had to say when the reaction stopped, a lot of people are saying 40-50 but I'm sure it's 60? Because that's when the volume of gas stopped increasing
I got electrolyte for that question about ionic compound one in section B

What did get for the way the electron flow will move?

Been losing so many marks here and there in paper 2.

For the moles one at the end did everyone get 0.02?

I got 60 too because it stopped at then it remained the same I'm pretty sure it's this answer.

I agree hahaha I couldn't do it
