btw, read equations of reaction of amphoteric oxides from federal book if u have it. the one by prestonoh my bad .. xD
thanks alot .. so CO is the only neutral oxide and Al2O3 PbO and ZnO the only amphoteric oxides ?
no problemThanks alot
Actually, chlorine is soluble in water as 7.1 g in 1 kg of water.Well halides are compounds of halogens ... so whatever the solubility is for chloride it is for all of them ..
Yes, as mentioned before by glamgurl, they are sparingly soluble.isn't Ca(OH)2 Insoluble ?
I think you know they are oxides which react neither with acids nor with alkalis!Which of the oxides are neutral I know carbon monoxide is one of the neutral oxides ..
Right.and which of them are amphoteric ? Aluminium Oxide , Lead(II)Oxide and Zinc Oxide are the only ones right?
http://www.xtremepapers.com/communi...apers-marking-schemes-examiner-reports.11543/hi there im searching for oct/nov 9700 biology papers and the ms as well as chemistry 9701..any help?
Thanks alot GetSomeLife ..
Well one last question .. can someone list the most conman catalysts and in what reactions they are used .. ?
Like Iron is the catalyst used in the Haber process .. If there is a list can anyone link me to it? thanks !
can anyone tell me why we only use AC current for a transformer? cant D.C be used here also?
can anyone tell me why metals exist as atoms???
yes..... but the thing is, we havent done the faraday's ring experiment. my teacher said it wasnt in the syllabus. so we just have done transformer, lenz's law and the ac generator and dc motor.
I didn't quite get your question ?.. All Non-metals , metals exist in the form of atoms ..[/quote
i mean why do they exist as monoatomic ??I didn't quite get your question ?.. All Non-metals , metals exist in the form of atoms ..
i mean why do they exist as monoatomic ??
so NaCl isnt a diatomic molecule?That is because metals only make Ionic bonds , and for an element to make a diatomic molecule, they need to be covalently bonded.
Only Elements which are Gases (except Noble Gases) and Halogens are present in the diatomic form.
so NaCl isnt a diatomic molecule?
as we go deep its does become difficult!!!!so this why i asked.Oh it isn't mentioned? i didn't c it... but to b on the safe side i wud suggest that u do it ... its not that difficult either.
