Home / summary of reaction types worksheet answers 9.2

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. |

✅ Did you label all 20 equations correctly? (Check the "why" column above). ✅ Did you use the for single replacement? (If the free element is below the metal in the compound → NR for "No Reaction"). ✅ Did you use the Solubility Rules for double replacement? (If both products are aqueous → NR ). ✅ Did you balance oxygen last for combustion? Need More Practice? If your worksheet answers didn't match this summary, don't worry. Reaction classification takes repetition. Focus on the pattern (the general form like A+B→AB ) rather than memorizing every specific chemical.

Happy balancing!
