its H2S hydrogen sulfide and i am afraid that two direction movement is right because the kettle runs on ac as said by Osaid Zahid. In ac, electrons move to and froand plz to be noted ac and dc is in the syllabus of chemistry saw questions in past pprs in ac and dc
But than y did they mention "electric kettle" ... From our knowledge of chemistry only, v were supposed to know that electrons in a circuit move in one direction only
Arey u ppl r making a blend of physix n chemits H2S hydrogen sulfide and i am afraid that two direction movement is right because the kettle runs on ac as said by Osaid Zahid. In ac, electrons move to and fro
have v studied anything known as A.C in chemistry? Also the ques did not specify whether it was really A.C or not.
It was Easy
exactly my case
same here!
but i got the last part of b10 totally wrong cx the time was theoretically over and because of the nervousness i couldnt think of anything
are you talking about the last part of b10??
in my center the generator does come on ALMOST immediately but sometimes theres 1-2 min gao b/w the switch.....should I b rebellious over this?Yaar ye tum log k center main mazay hain. Loadshedding - Zindabad (only for CIE season).
the question was>?You're the first person I've come across that has gotten it right. Congrats.
higher and same i guess....
i dnt thnk so..... i wrote smthng else..i dnt remember wht but it wasnt calcium cx i wrote calcium and then was conviced due to some stupid reason tht it cldnt b calcium...
i wrote copper oxide...is it correct?
Nope. Metals form basic oxides. NaOH is already a base, so it wont react with copper oxide
in one direction only ....not sure though.....luked more of a physics question to me
It was about H4NO3V, v had to name two ions present in itthe question was>?
dumb me! stilll theres a part of my head saying tht i didnt chose copper...
idk why...aniways lets hope 4 da best!
there was a question that stated tht sodium hydroxide(or idk smthng els) is added and a gas is liberated that produces turns red litmus ppr blue....are u talking about the same question??
Lets just hope u did notdumb me! stilll theres a part of my head saying tht i didnt chose copper...
i wrote nh4+ (4 idk wht lame reason) i jst thought ammonia will be produced so ammonium ions will be there and 4 the other ion i wrtoe al+3 cx of tht nitrate ion test v learnt...when sodium and aluminium ions come in contact ammonia is produced...but i guess i was applying the wrong concept at the wrong place
