1) We need to find out every molecule.
Reactants
Baking soda: NaHCO3
Citric acid: C6H8O7
Water: H2O
Possible products
Sodium citrate: Na3C6H5O7
Sodium nitrate: NaNO3
Ammonium nitrate: NH4NO3
2) Set the chemical equation (reactants)
[tex]\text{NaHCO}_3+C_6H_8O_7+H_2O\text{ = }[/tex]3) According to the reactants we can expect in the products' side elements such as Sodium, Carbon, Hydrogen, and Oxygen. So, those compounds with Nitrogen cannot be in the reaction.
