My coursework is an A or A*. I think i did really well in biology but not so well in chemistry. I am not that good at physics. What grade would i need in Chemistry and physics to get an A overall??

Thanks

Yeah, thats correct Fe3+ and Cl-

Although, Cl3 - would be wrong because that wouldn't ionise normally, it would separate completely.

The electrons seems fine as well!

The ABCD question was worded so weirdly I looked over it like three times and I'm 50/50 even now. Tbh it was the worst question made little sense.

Rest of the exam was great though

Positive - copper ion
Negative - electron

Sorry I've just reread your previous question, for an A overall (seeing as your coursework would be an A-A*) you'd need mid Bs-low As.

I have a secure A* in the coursework, I'm sure I got an A* in unit 1 as I remember feeling soooo good after, I think I scraped an A* for today's exam...so what do I need for C7 to get an A* overall? Obviously I'm going to aim as high as I can, but C7 is the hardest 7 for me so realistically if I get an A...will I still get an A* overall?

OOH! Forgot about this question. It's about the Cl- one, what did everybody get? For the second part of the question I put Cl- ion and I can't remember the metal but 3+ ion

i really want an A* overall for additional science. i have a really high A* in coursework and i think i would get about 45 for biology and 34 for chemistry and if i get about 40 for physics, can i still get an A* overall??

Exactly what I said.
weren't a and b similar because they're both acids so they give a low ph reading and both hydrochloric acid and sulfuric acid produce hydrogen when reacting with metals.
also c was different because Hcl wouldn't produce a precipitate when sulfuric acid would. And vice versa for d (sulfuric acid wouldn't produce a precipitate with silver.

What were your observations?
