Determining the Decomposition of NaHCO3
Initial Mass: 7.53 g
Final Mass 2.8 g

Reaction I:
Theoretical Yield - 3.59g
NaHCO3(s) → NaOH(s) + CO2(g)

Reaction II:
Theoretical Yield - 2.78 g
2NaHCO3(s) → Na2O(s) + 2CO2(g) + H2O(g)

Reaction III:
Theoretical Yield - 4.75 g
2NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)

Assuming the reaction went to completion, which of the three reactions correctly identifies the decomposition of the sodium bicarbonate under high heat?
NaHCO3(s) → NaOH(s) + CO2(g)

2NaHCO3(s) → Na2O(s) + 2CO2(g) + H2O(g)

2NaHCO3 (s) → Na2CO3(s) + CO2(g) + H2O(g)
