so why petrol is better than bitumen? Suchal Riaz Suchal Riazthe more carbon atoms, the more heat in organic compounds of same homologous series.

wait wait.
CaCO3 will decrease in mass-understood
CO2 will increase in mass-understood
HCl-moles will decrease, so won't the volume of HCl decrease too, causing the concentration to remain constant?
Petrol is Easily Ignited whole Bitumen will take lot heat to igniteso why petrol is better than bitumen? Suchal Riaz Suchal Riaz
http://easycaptures.com/fs/uploaded/627/3978817638.jpghow to learn the qu. on test,observation and conclusion by heart . cations and anions. plzzzzzzzzzzzzzzz helppppppppppp
so u mean bitumen will give more temperature rise but will also take more heat to ignite?robinhoodmustafapart b. as the size of molecules increases the temperature rise done when it is burned increases or decreases? pls explain

violent reaction and sodium hydroxide with sodium and rusting with ironIfa a small piece of sodium and a small piece of iron is added to separate samples of water what would be observed?
are there any chemistry atp notes? robinhoodmustafa Suchal Riaz
violent reaction and sodium hydroxide with sodium and rusting with iron
nothing would be observed for iron as its reaction with water is extremely slowIfa a small piece of sodium and a small piece of iron is added to separate samples of water what would be observed?
U be doing Merchant Paper... Am I rightIfa a small piece of sodium and a small piece of iron is added to separate samples of water what would be observed?
No Where bhai!Guys from where can i get June 1995 chem atp?

From which chapter is that?can anyone explain dehydration of alcohol
in the pipette question the mark which shows 25 cm3 should be on top part. right?(in imran merchant paper)U be doing Merchant Paper... Am I right
I just did that q
Sodium : White lilac flame, Very Vigorous reaction, metal be floating on top (Because grp 1 metal r light) and Metal oxide be seen below
Iron: It doesnot react with water so No Reaction
I am Confuse that it Iron is presence of water can get rusted so why not Iron Can react with Water?
I was thinking of the exact same thing. Iron reacts with water (and air) to form rust (brown solid).U be doing Merchant Paper... Am I right
