A Yes Yes
B Yes no
C no Yes
D no no
I just ticked the option C and the answer was right but i donno how, so ca anybody plz explain be how do u call Q an acidic oxide???
Thanks in advance...

Well, hydrocarbons consist of only C and H atoms...so hence glucose is not hydrocarbon.....CO2 is acidic should be known :P....CO2 forms carbonic acid in soln...it's an acidic oxide...cummon dude
Ghost Of Highbury:
yeah..that was correct...
as nid said..CO2 forms carbonic acid
metal oxides forms an alkali when dissolved in water
and non-metal oxides form acid..
so..yaeh..C is a non-metal..so
the answer is C
@nid - he has taken combined science dude...not pure chem/phy/bio
nid404:
oh ok....
