1. two types of reaction occur when baking soda and vinegar combine. the first is a double replacement reaction. write a balanced equation for this reaction. balance both equations. (hco3) + h(c2h3o2) → (c2h3o2) + → + 2. what type do you think the second reaction is? why?
First reaction is balanced, there is no need to write coefficient 1 in front of molecule.
1H2CO3 → 1H2O + 1CO2
Second reaction is also balanced. This type of reaction is calling chemical decomposition or analysis, because one molecule separats into its two simpler compounds.
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).
