Final answer:
The correct balanced chemical equation for the decomposition of sodium hydrogen carbonate into sodium carbonate, carbon dioxide, and water is: 2 NaHCO₃(s) → Na₂CO₃(s) + CO₂(g) + H₂O(l).
Step-by-step explanation:
The balanced chemical equation for the decomposition of sodium hydrogen carbonate (baking soda), NaHCO₃, into sodium oxide, carbon dioxide, and water is:
2 NaHCO₃(s) → Na₂O (s) + CO₂(g) + H₂O(g)
This is not the correct balanced equation for the given reaction. The correct balanced equation should be:
2 NaHCO₃(s) → Na₂CO₃(s) + CO₂(g) + H₂O(l)
In this decomposition reaction, sodium carbonate, carbon dioxide, and water are produced from the single substance sodium hydrogen carbonate.
