given the following reactants, predict which type of reaction this can be?
sodium bicarbonate
synthesis
decomposition
double replacement
combustion
single replacement

Explanation:

Sodium Bicarbonate (NaHCO₃) typically undergoes decomposition reactions, especially when heated, breaking down into simpler substances (like Na₂CO₃, H₂O, and CO₂). Synthesis reactions require multiple reactants combining, double replacement needs two compounds, combustion needs a fuel and O₂, single replacement needs an element and a compound. Since only one reactant (sodium bicarbonate) is given, decomposition (where a single compound breaks down) is the most likely.

Answer:

B. Decomposition
