You need to use sodium carbonate when you are attempting to diazotize a poorly soluble acid, such as sulfanilic acid. m-nitroaniline isn't acidic, so adding sodium carbonate would have no effect.
No, You would need a weak acid so the solution would be acidic
Since it is a double displacement and the products of the reaction would be sodium nitrate and calcium carbonate, the precipitate would be calcium carbonate. This is because this reaction is a solubility based reaction, and sodium nitrate is a soluble compound (every metal is soluble in nitrate, and sodium dissolves in almost everything too). Whereas calcium carbonate is insoluble, and therefore will remain solid and form the precipitate.
DEPENDS... I would say no at first... but if its just for neutralising an acid than sodium carbonate is probably better... Seek professional assistance before messing around with chemicals though...
No reaction would Occur. => No product is formed
Sodium carbonate is used for neutralization in detergent synthesis because it is basic enough to deprotonate the precurser to the synthetic detergent but if excess is added will not result in a soap with a very high pH as NaOH would.

Sodium carbonate would be deposited at the bottom of the solution.
If you mix sodium carbonate and water, you would observe that the sodium carbonate dissolves in the water. This is because sodium carbonate is highly soluble in water. The solution may also become slightly warm due to the dissolution process.
Calcium carbonate is not soluble in water, sodium carbonate is soluble in water. Dissolve the mixture and filter: the Na2CO3 pass the filter as a solution and CaCO3 remain on the filter. Gently warm the solution to obtain crystallized sodium carbonate.
Copper carbonate would precipitate if you combined solutions of copper (II) chloride and sodium carbonate.
By distillation or evaporation of water
It would have to be Na(HCO3)2 But no such thing exists.This would require sodium to form a 2+ ion.It can only form a 1+ ion.The real formula for sodium hydrogen carbonate is NaHCO3 .This would be sodium I hydrogen carbonate, though the roman numeral is not needed in this case.
Firstly, they'll react each other forming sodium hydrogen carbonate and sodium chloride. If there is excess HCl, the sodium hydrogen carbonate would further react till sodium chloride and evolve carbon dioxide.
Sodium carbonate and and sodium hydrogen carbonate form a buffer solution.

Blue litmus turns red in acid. Sodium carbonate solution is alkaline (basic), so nothing will happen when blue litmus is put into this. Red litmus will turn blue if added to sodium carbonate.
