Question

Two types of reactions occur when baking soda and vinegar combine. The first is a double replacement reaction. Write a balanced equation for this reaction. Please balance both equations.

__Na(HCO₃) + __H(C2H₃O₂) → __Na(C₂H₃O₂) + __H₂CO₃
__H₂CO₃ → __H₂O + __CO₂

Answer 1

1) Balanced chemical reaction:

1Na(HCO₃) + 1H(C2H₃O₂) → 1Na(C₂H₃O₂) + 1H₂CO₃.

Double replacement reactions (double displacement or metathesis reactions), two ionic compounds are exchanged, making two new compounds.

2) Balanced chemical reaction: 1H₂CO₃ → 1CO₂ + 1H₂O.

H₂CO₃ is carbonic acid.

CO₂ is carbon (IV) oxide or carbon dioxide.

Chemical decomposition is the separation of a single chemical compound (in this example carbonic acid) into its two or more simpler compounds (in this example water and carbon dioxide).

Answer 2

The chemical equation for the Vinegar & Baking Soda reaction is: NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO-(aq) with s = solid, l = liquid, g = gas, aq = aqueous or in water solution Another reaction is: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2 The chemical reaction actually occurs in two steps. First, there is double displacement reaction in which acetic acid in vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid: NaHCO3 + HC2H3O2 → NaC2H3O2 + H2CO3 Then,Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas: H2CO3 → H2O + CO2
