balance?

NaHCO3 + CH3COOH = Na(CH3COO) +H2O +CO2.

Balancing a chemical equation is very important in case of both laboratory and industrial purpose. It gives us the stoichiometric ratio of the reactants which reacts together and how much product we can expect from the reaction.

Here, sodium bicarbonate reacts with acetic acid or vinegar to produce sodium acetate, carbon dioxide and water. Actually carbonic acid is produced which is decomposed to carbon dioxide and water.

Now balancing the equation, we get,

NaHCO3 + CH3COOH = Na(CH3COO) +H2O +CO2.

So this reaction is already balanced. It means 1 mole of each reactant reacts to produce 1 mole of each product.

it's all four options.
