Challenging Chem combined Question - Mod 7+8 (1 Viewer)

[Isomorph]

I posted this elsewhere on the forum, but for anyone who is interested here's a fairly challenging problem that combined module 7 and 8 attached.

Feel free to have a go if you're interested and post your attempts here if you want.

Btw there's two questions there, the 1st one is the one that's nice.

Here is another neat problem, quite challenging as well for those interested!

One last one that I'll post up, Question 29, probably more challenging than either of the previous ones. It also incorporates some of those skills from year 11 and previous year 12 modules so it's good for review.

Like before, give it a go if you're interested and feel free to post your attempts here.
