Final answer:
The balanced equation for sodium bicarbonate reacting with citric acid is 3NaHCO3 + C6H8O7 → 3CO2 + 3H2O + Na3C6H5O7.
Step-by-step explanation:
The balanced chemical equation for the reaction between sodium bicarbonate and citric acid is:
3NaHCO3 + C6H8O7 → 3CO2 + 3H2O + Na3C6H5O7
In this reaction, sodium bicarbonate (NaHCO3) reacts with citric acid (C6H8O7) to produce carbon dioxide gas (CO2), water (H2O), and sodium citrate (Na3C6H5O7).
