welcome. by crack i meant that who answer a simple question with so many complex terms??you are calling your bro crack btw thank you
he wont. though i wish he would. n trust me, i have told him a thousand times that he is. so no worries. =)Hope your brother doesn’t read that
when did v read ds??..o_0it is the usual acid catalyst for the conversion ofcyclohexanone oxime to caprolactam, used for making nylon. It is used for making hydrochloric acid from salt via the Mannheim process. Much H2SO4 is used in petroleum refining, for example as a catalyst for the reaction of isobutane with isobutylene to give isooctane, a compound that raises the octane rating of gasoline
thankyou soo much!!..CaO is also used but others are relatively used more
hahaha dunt worry. read ma post. meine fahad bhai se question pucha tha n usne ye bola tha so i copy pasted the same answer. wo zara apne dimag wale answer karta ha na. dunt worry. we jes read the overview ov these =)when did v read ds??..o_0
hahaha ritie!..hahaha dunt worry. read ma post. meine fahad bhai se question pucha tha n usne ye bola tha so i copy pasted the same answer. wo zara apne dimag wale answer karta ha na. dunt worry. we jes read the overview ov these =)
Chemistry 5070
May/June 2005 Paper 4
Q3 c) i)
Shouldn't the answer be Oxygen? The Hydroxide Ion is more Reactive then the Chloride Ion, and unless sodium chloride is concentrated, it wouldn't get discharged. So why does the marking scheme say chlorine is the answer?
Explain charging of solids involve movement in electrons
Describe the separation of charges by induction
Describe examples where charging could be a problem.eg.lightning
Please answer these
See this in any aqueous solutions the discharge occurs like in concentrated solutions so if it says aqueous solution of sodium chloride then chlorine discharges like in concentrated solutions remember this as a rule
Those aren't in the book....if you can plsCmon man these are so big to answer dont u have a book to read from all this
so if the question doesn't specify whether the solution is dilute or concentrated , we assume it to be concentrated . Is that right?
all nitrates are solubleCould someone please repeat the solubility chart for me ? that which of them are soluble and which are insoluble ?
i know that All Nitrates are soluble .. what are the others ? i have a test tomorrow so please help .. thanks
Carbonates ?
Halites ?
Oxides And Hydroxides ?
Sulphates ?
are there any which i missed?
all nitrates are soluble
all carbonates are insoluble except sodium, potassium and ammonium carbonates
all sulfates are soluble except calcium, barium and lead
all chlorides are soluble except lead, silver and mercury
all hyrdoxides of group 1 are soluble. ammonium hydroxide is soluble. calcium hyrdoxide and aluminium are sparingly soluble.
have no idea about halites. sorry
umm em a gurl =PThanks alot man !! i wasn't sure if i wasn't sure .. just wanted to check
Well halides are compounds of halogens ... so whatever the solubility is for chloride it is for all of them ..
isn't Ca(OH)2 Insoluble ?
Which of the oxides are neutral I know carbon monoxide is one of the neutral oxides ..
and which of them are amphoteric ? Aluminium Oxide , Lead(II)Oxide and Zinc Oxide are the only ones right?
oh my bad .. xDumm em a gurl =P
hmm chlorine is soluble in water
yeah it is. but sum days ago, sum1 from around here told me k its sparingly soluble
yea you are right
right again.
oh my bad .. xD
thanks alot .. so CO is the only neutral oxide and Al2O3 PbO and ZnO the only amphoteric oxides ?
