Study Notes
Chemical Reactions
- Chemical reactions involve breaking and forming bonds between atoms to create new products
- Chemical reactions require collisions and overcoming energy barriers; some reactions are faster than others.
- Reactions can be categorized into five basic types: Combination, Decomposition, Single-Replacement, Double-Replacement, and Combustion
Combination Reactions (Synthesis)
- Two or more reactants combine to form a single product
- Example: 2Na(s) + Cl₂(g) → 2NaCl(s) (sodium reacts with chlorine to form sodium chloride)
Decomposition Reactions
- A compound breaks down into simpler substances (elements or simpler compounds)
- Example: 2NaOH(s) → Na₂O(s) + H₂O(g) (sodium hydroxide decomposes into sodium oxide and water)
Single-Replacement Reactions
- One element replaces another element in a compound
- The replacing element must be more reactive
- Example: Mg(s) + Cu(NO₃)₂(aq) → Mg(NO₃)₂ + Cu(s) (magnesium replaces copper in copper (II) nitrate)
Double-Replacement Reactions
- Positive and negative ions in two compounds exchange places to form new compounds
- Example: AB + CD → AD + CB (ionic compounds exchange partners)
Combustion Reactions
- Reactions that involve oxygen and produce energy (light and heat)
- Often considered a special kind of combination or replacement reaction because oxygen is always involved
- Example: 2H₂(g) + O₂(g) → 2H₂O(g) (hydrogen and oxygen react to make water)
- Example: C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g) (propane burns in oxygen to form carbon dioxide and water)
