in synthesis reactions, there are always more ____ than\na reactants, products\nb products, reactants\nin the decomposition example seen here, what does b represent?\na h\nb o\nwhat kind of reaction is represented here: h₂co₃ --> h₂o + co₂\na synthesis\nb decomposition
Answer
Brief Explanations:
- In synthesis reactions, multiple reactants combine to form a single product, so there are more reactants than products.
- 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.
- 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:
- A. reactants, products
- B. O
- B. Decomposition
