What did you guys get for metal X? My chemistry teacher got Magnesium but half our class got nitrogen.... so I'm not sure. Btw I got nitrogen as well.
-
its definitely lead
-
nitrogen metal????
i got lead
-
half the class got nitrogen metal????? ??????? ????????? !!!
-
If I write Pb instead of Lead, will I lose mark? :/
-
Omg are you serious :'(
So many of us got N
-
If I write Pb instead of Lead, will I lose mark? :/
ofc not
-
100 % lead, because the metal needs to have charge of 2+
-
N isn't a metal...
And I'd be worried if your actual teacher got Magnesium.
(Lead for sure)
-
Yeah, I got lead too.
-
FML i wrote helium
-
Under pressure I multiplied by 2 the first time I did the question and got chromium, which fortunately I realised was wrong given chromium ions have an oxidation number of +3 haha, and X ions needed to be +2.
Was definitely lead though. No offense to the people who answered with gases but that is kinda funny :P Totally understandable given exam pressure, don't beat yourself up too much (:
-
Hey if I multiplied by 2 but then used that answer to work out molar mass in the next part what mark will I get for the last part if I got chromium due to consequential marking??? I'm sooooo stupid!!!!!!
-
Lead.
-
did we have to say lead II or was lead just okay?
-
just lead would've been fine i think
-
Yay, I got lead! That should mean I sured up 5 (at least 4) marks I was unsure about
-
...Lead (Pb)...
-
I Got lead. How did people get chromium or nitrogen. ??? Maybe I got it wrong. :P
-
Nah, relax - it was lead :)
-
Oh, that makes me feel tonnes better, because I sometimes find that under pressure, I stuff up math related question because I forgot divide or multiply or used 0.5mol instead of 0.05mol to find concentration, which I believe I did in the mid-year. I felt so pissed off with myself after that. Silly mistake.
