What did you guys get for Element Y? I got Argon...


i was confused by that and put down mg, i just thought the first ionization energy was too low to be a nobel gas

SF6 has a bond angle of 90


Sf6 is 90 and other one was 107 I think????

2nd Balanced Equation: Cu2(OH)2CO3(s) + 4 HCl(aq) = 2 CuCl2(s) + CO2(g) + 3 H2O(l)


I put HCO3 whoops

I put chlorine too.

Buuuut I just googled the ionisation energies and sulfurs is 1000 which was the FIE so it must be sulfur.

I thought the test overall was pretty easy. Ill get working on an unofficial one when i get home!
Y was Sulfur sorry

No, it was sulfur


****, just realised I used electron configuration instead of electron arrangement. Would I still get method marks for the explaination?

how did you get 49.3
1090/2258 multiply by 100 numbers might be wrong.I calculated theoratical then 1.09 over theoratical x 100

did you not work out the mass for the other reactant to get like 2-3 kg or something which gets you 6. somthing kg for overall then do the 1.09 over that

What was the question again?

I know I put Silicon, sulfur and sulfur for three different questions
