Summary Of Reaction Types Worksheet Answers 9.2 May 2026

If you’re working through Chapter 9.2 in a standard high school chemistry curriculum (such as Pearson or McGraw-Hill), you’ve just tackled the five major classes of chemical reactions. This worksheet is a classic: it asks you to identify, predict products, and balance equations.

| Equation Example | Reaction Type | Why? | | :--- | :--- | :--- | | 2Na + Cl₂ → 2NaCl | | Two elements combine into one compound. | | 2H₂O → 2H₂ + O₂ | Decomposition | One compound breaks into two simpler substances. | | Zn + 2HCl → ZnCl₂ + H₂ | Single Replacement | Zn replaces H in the acid. | | AgNO₃ + NaCl → AgCl + NaNO₃ | Double Replacement | Ag and Na swap places (forms a precipitate). | | CH₄ + 2O₂ → CO₂ + 2H₂O | Combustion | Hydrocarbon + Oxygen → CO₂ + H₂O + heat. | summary of reaction types worksheet answers 9.2
