ok my question is: wats the reaction to make sodium carbonate NaCO3 ?

 

[respect1]

I am guessing naoh + caco3 --> naco3 + caoh...not sure

thanks guys but i dnt think the displacement reaction will work here
i think a reversible reaction will do ..... CaCO3 --- CaO + CO2
just like that ............it maybe .....NaCO3 ---- Na2O + CO2

wat do u ppl think?

 

[haochen]

group 1 carbonate decompose on heating so NaCO3 dont have reaction

 

[Outofideaz]

i didnt get u

 

[haochen]

u heat NaCO3 ---> no reaction

group 1 metal, when u heat them they dont give any product.

in the exam they might asked if we heat NaCO3 , what observation will u see??
so the answer is they dont decompose or no reaction
ONLY FOR GROUP 1 METAL

hope u got it

Ahhh ... now i got it

Cheers !
