Answer:
2NaHCO3(s) --> NaCO3(s) + H2O(g) + CO2(g)
Explanation:
The Fomular for the compounds is given as;
Sodium Hydrogen Carbonate - NaHCO3
Sodium Carbonate - NaCO3
Water Vapor - H2O
Carbon dioxide - CO2
The equation is given as;
NaHCO3 --> NaCO3 + H2O + CO2
The balanced equation is given as;
2NaHCO3(s) --> NaCO3(s) + H2O(g) + CO2(g)
