Types of Chemical Reactions Quick Check

A reaction where one element replaces another in a compound. Example: $$Zn + 2HCl → ZnCl_2 + H_2$$ .

A reaction that involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. General formula: $$C_xH_y + O_2 → CO_2 + H_2O$$ .

A reaction where a single compound breaks down into two or more simpler products. Example: $$2KI → 2K + I_2$$ .

A reaction where two or more reactants combine to form a single product. Example: $$Cu + SO_4 → CuSO_4$$ .

A reaction where two compounds exchange ions to form two new compounds. Example: $$BaCl_2 + 2KI → 2KCl + BaI_2$$ .

1. Synthesis (Combination) 2. Decomposition 3. Single Replacement 4. Double Replacement 5. Combustion.

A + B → AB, where A and B are reactants that combine to form a product.

AB → A + B, where a compound breaks down into its components.

A + BC → AC + B, where an element replaces another in a compound.

AB + CD → AD + CB, where ions in two compounds exchange places.
