Question

2NaHCO(3) → Na(2)CO(3) + CO(2) + H(2)O ... [ the parenthesis mean its a subscript ] .. Which one is the reactant and which one is the product?

Answer 1

Chemical equations show the reactants and products, as well as other factors such as energy changes, catalysts, and so on. With these equations, an arrow is used to indicate that a chemical reaction has taken place. In general terms, a chemical reaction follows this format:

Reactants→Products

So NaHCO₃ is reactant and Na₂CO₃ + CO₂ + H₂O are products.
