B & C also have double bondsunsaturated molecules with double bonds undergo addition reaction ... so ans is d..
Only alkenes undergo addition polymerization. B is carboxylic acid and C is ester.B & C also have double bonds
oh okOnly alkenes undergo addition polymerization. B is carboxylic acid and C is ester.
Oxidizing an alcohol(T) gives a carboxylic acid(S). Potassium dichromate is an oxidizing agent.
ill die in b/w oxidation and reductionOxidizing an alcohol(T) gives a carboxylic acid(S). Potassium dichromate is an oxidizing agent.
potassium dichromate is itself an oxidising agent and is used as a test for reducing agent?Oxidizing an alcohol(T) gives a carboxylic acid(S). Potassium dichromate is an oxidizing agent.
Yeah. When reducing agents like KI get oxidized due to potassium dichromate, there is a colour change.potassium dichromate is itself an oxidising agent and is used as a test for reducing agent?
yeah i got the real ones .....CHEMISTRY CIE O LEVEL REVISION CHECKLIST RIGHT HERE!!
Just kidding - I need it, anybody has the link?
2NH3(g)+3CuO(s)=N2(g)+3Cu(s)+3H2O(g)what happens when ammonia is passed through cuo
1.c it is inverted which shows the gas to be collected is light.Only light one is Hydrogenhttp://papers.xtremepapers.com/CIE/Cambridge International O Level/Chemistry (5070)/5070_s10_qp_12.pdf
Someone please explain Questions ; 1 , 4 , 24 , 25 , 28
My worst p1
1.c it is inverted which shows the gas to be collected is light.Only light one is Hydrogen
4.It says present in solution AFTER reaction,CaCl2 is a soluble salt,thus Cl ions would be present in solution.
24.Oxygen is above iron in reactivity series.
25.Only zinc reacts with dil HCL,copper deposit is seen
28.Magnesium is more reactive,thus reacting more.
Mixture would contain magnesium which could still increase H2 production,while pure Zn would not produce that much.Thank youu so much
Damn you're smart.
But Q)28, how did we deduce the least volume of H2?
Mai to movie dekh ra hoon bhai,chemistry has abandoned mewhat years r u guys focusing?
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.
