first option is aluminium -,-aluminium
argon
iron
nickel
nitrogen
phosphorus
sodium
which of the above is the answer? :
(c) reacts with oxygen to give an acidic oxide,
Nitrogen or phosphorus?? (nothing else i guess?)
WHY DOES THE BLOODY MARK SCHEME SAY THAT ITS ALUMINIUM OXIDE ITS NOT EVEN IN THE BLOODY OPTIONS -_- the question is from s06 qp2 A1

The answer is Aluminium and Nitrogen.Aluminium forms amphoteric oxide which shows the properties of both acids and alkalies.aluminium

The answer is Aluminium and Nitrogen.Aluminium forms amphoteric oxide which shows the properties of both acids and alkalies.
Yes,its not acidic but it shows the properties of both.So nitrogen will be the correct one.And i searched the answer for ur question on google it says that aluminium oxide is insoluble in water so it doesnt change the litmus clr.But Al203 is NOT an acidic oxide. it acts as an acidic oxide with an alkali to do the neutralization reaction but itself is NOT an acidic oxide.. Nitrogen is the right answer imo.
btw what color would a red litmus show in Al203?

is very INsoluble in water, so it doesn't change lithmus paper color.Read more
uhh... are u sure u saw the ryt answer. just to b sure double check the question and the answer too. if its still true then check the examiner report b/c thats stupid. they shud have given both nitrogen and aluminium oxides in the marking scheme. if they are considering it to b acidic. this is confusingaluminium

19 wala is 40 dont know how but 22 wala notice curve 2 it is more steep and has a larger height this shows either conc or number of moles is alterd only one option shows this toh it is b

Ahan thnku19 >B ? 40 Tonnes .. as NH3 will be divided equally in both the parts and then compare the moles.
22 > B?
