check ur 2nd equations there are too many Cl in the reactantsCl2 + 2NaOH --> NaCl + NaClO + H2O
3Cl2 + 6NaOH --> NaCl + NaClO3 + 3 H2O
right?

Thanx a bunch for this man!Here's the diagram:
I didn't check the mark scheme though....
I'll do it now..
plz someone give me a reaction of carboxylic acid with carbonates
syed1995
In esterification we have to heat with reflux and use H2SO4 as a reagent right?? syed1995 and MustafaMotani

thanksss man!! thats the right one,.... yeah but according to syllabus i think we do need to know.... and seeing the imbeciles the cie people are u never know wat hey might give in the paper -__-RCOOH + XCO3 ---> CO2 + H2O + salt
e.g. 2CH3COOH + CaCO3 ---> (CH3COO)2Ca+ H2O + CO2
I got it off google
I don't think you need to know the equation. In the papers I answered some papers, according to that what I know is that you need to know that CO2 is given out (effervesence) and this CO2 turns limewater milky.
yuppoah yeah.. it's 5NaCl..
its by using a filter paper soaked in acidified K2Cr2O7 i think.... it turns orange to green.... the one we did in o levelsWhat are the tests for identifying gases?
like for SO2?
SO2 turn dichromate from orange to green .. in other words it gets oxidised ..What are the tests for identifying gases?
like for SO2?
nothing i guessWhats the difference between writing 3+ and +3 in oxidation numbers??please help
plz come to that other thread that is for the AS questions only...Whats the difference between writing 3+ and +3 in oxidation numbers??please help
Wa iyyaki sisThanx a bunch for this man!
JazakAllah khair
PS: That's pretty neat ^_^
PPS: Oh and you've placed the ammonium ntrate just like that on the tube, i think it needs a porcelain dish
Ohh... thanks dude... i didnt know that... i'll make a note of that point..
