guys for the plants question could you say keep them both in the same area and check them regularly

Yeah, I said keep them both in the same area for growth so the independent variable is only the water/acid. But some of my friends said put a range of pH but I think our answers are valid too.

Yes that’s what I put because hcl is corrosive, I saw that on the mark scheme of a past paper so should be correct

It was for Chlorine gas, not HCl

does anyone know what the balanced equation was? I thought I’d done correctly it but apparently it had a 16 in it which I didn’t get

2KMnO4 + 16HCl → 2KCl + 2MnCl2 + 5Cl2 + 8H2O

If i said increase the air ventilation in the room so you dont inhale the toxic chlorine gas would i get the marks

for some people they had 8, as they made the other value 2.5 (which you can do)

I had 24 for one of my numbers for the balancing equation is that wrong because I made it equal on both sides

I forgot to multiply out the balanced equation, so I put KMnO4 + 8HCl →KCl +MnCl2 + 2.5Cl2 + 4H2O

would I still get full marks

I said fume cupboard bc fumes dangerous and oxidising and stop them being inhaled

Wow I literally revised that before I left my house and still didn't put that down, also I put use mask so you don't inhale, would that still be fine?
