Answer

Brief Explanations:

  1. In synthesis reactions, multiple reactants combine to form a single product, so there are more reactants than products.
  2. For the decomposition of $H_2CO_3\rightarrow H_2O + CO_2$, in the chemical formula of water ($H_2O$) and carbon - dioxide ($CO_2$), oxygen is a common element. If we assume a general decomposition context related to the elements in the reactant $H_2CO_3$, oxygen is a likely candidate for what 'B' could represent.
  3. The reaction $H_2CO_3\rightarrow H_2O + CO_2$ is a decomposition reaction as a single compound breaks down into two simpler substances.

Answer:

  1. A. reactants, products
  2. B. O
  3. B. Decomposition
