Because it has protective coating around itWHY DOES THE QUESTION SAYS THAT THE REACTION DOES NOT TAKE PLACE AT ROOM TEMP
I beleive

U ARE WRONG CHEMICAL PROPERTIES DEPEND UPON ELECTRONIC CONFIGThey depend upon element's Electronic Configuration!
which year mcq.. ??WHY DOES THE QUESTION SAYS THAT THE REACTION DOES NOT TAKE PLACE AT ROOM TEMP
Yeah! Thanks!27a and 12c. duke displacement reaction requires no heat you know.
I read it on a website!U ARE WRONG CHEMICAL PROPERTIES DEPEND UPON ELECTRONIC CONFIG
J10 P12which year mcq.. ??
Its exhothermic, as told by A starBecause it has protective coating around it

Beg your pardon!really??

Which equation describes the most suitable reaction for making lead sulphate?
A Pb + H2SO4 → PbSO4 + H2
B PbCO3 + H2SO4 → PbSO4 + CO2 + H2O
C Pb(NO3)2 + H2SO4 → PbSO4 + 2HNO3
D Pb(OH)2 + H2SO4 → PbSO4 + 2H2O
ms says its C buh why not D??
thankyou...lead sulphate is an insoluble salt
so it has to be prepared by ionic precipitation of soluble salts
in D Lead hydroxide is insoluble(only Group 1 and 2 Metal Hydroxides are soluble)
Appreciated , but you are a bit too late brother!Reactivity series !
Please (K) send (Na) cats (Ca) monkeys (Mg) and (Al) Zebras (Zn) In (Fe) large (Pb) huge (H) cage (Cu) . Make (Hg) sure(Ag) packed/padlocked (Pt)
Hope it helps, it did help me
it was done by meAppreciated , but you are a bit too late brother!
4-5 Mnemonics have already been shared while Chemistry ATP was discussed!
P.S this one was included in that too!
You mean, you made that mnemonic?it was done by me
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
