Heyy you ready for it?
Mostly, I'd been doing well the whole year, and then the specimen paper's came and ruined my life.
Paper 1 went okay though, and I tend to like Organic more, though.
How about you?

Dw, we all know that feel.
Could some kind person help me with the following?
Q1. If I change the solid product from an equilibrium mixture, though the equilibrium constant remains the same (as the solid is not included in equilibrium constant equation), would the equilibrium concentrations remain same or would the reaction shift backwards as product is removed?and why?

Um more product would be produced if the product was removed as it is produced. The position of equilibrium should remain the same. If you post an example ques i might be able to explain it better

Q#11 (d)
:/ im really sorry but im not sure how to answer this. Im doing AS AQA chem. Ive done equilibrium and in relation to what you originally asked if you remove the product as its being produced the position of equilibrium will shift so more is being produced. But this question is asking about titrations and the container is sealed.
Maybe someone else might be able to help or you could look at the markscheme. Sorry

Yeah AQA but I'm the last year to do it
Can someone explain the final parts of this question? Where it says "Give the formula of the complex cobalt compound Z that you would expect.."
Thank you!
