  1. Physical Science: Chapter 7, Section 3Types of Chemical Reactions Types of Reactions 1. ________________________Reactions: • ________or more elements or compounds combine to form _______compound. • Example: 2Na(s) + Cl2(g)→ 2NaCl(s)

  2. Physical Science: Chapter 7Types of Chemical Reactions Types of Reactions 2. _______________________Reactions: • _____compound “_______________” to form __________________ compounds. • Example: CuCO3 (s)→ 1CuO(s) + CO2 (g)

  3. Physical Science: Chapter 7Types of Chemical Reactions Types of Reactions 3. _________________________________ • A “________active” element __________a “______active” element in a compound. • Example: Cu(s) + 2Ag(NO3)(aq)→Cu(NO3)(aq) + 2Ag(s)

  4. Types of Reactions 4. __________________________Reaction • A “_______active” ____replaces a “__________active” ______in a compound and a _____________forms. • A “______________________switch” • Also called _____________________or _________________reactions. • Example: Ag(NO3)(aq)+ NaCl(aq)→AgCl(s)+ Na(NO3)(aq)

  5. Physical Science: Chapter 7Types of Chemical Reactions Types of Reactions 5. _______________________ Reaction • A substance combines with _________ gas, releasing _______and _________. • Example: CH4(g)+ 3O2(g)→ CO2(g)+ 2H2O(g)

  6. Other Types of Reactions 1. __________________________(Redox) • Electrons are ______________from one species to ___________in the reaction. 2. ________________________reactions • An ________neutralizes a _________to form an __________ and __________. • They are similar to_____________ replacement reactions.

  7. Physical Science: Chapter 7Types of Chemical Reactions Practice Problems: List the TYPE of reaction for each of these: 1). CO2 + H2O → H2(CO3) 2). 2K(ClO3) → 2KCl + 3O2 3). 2C4H10+13O2 →10H2O + 8CO2 4). Na + Cu(NO3)→ Na(NO3)+ Cu

  8. Physical Science: Chapter 7Types of Chemical Reactions Practice Problems: LIST the TYPE of reaction for each of these: 5). NaI + Cl2→ NaCl+ I2 6). Ag(NO3) + NaCl→AgCl + Na(NO3) 7). 2LiI + F2→ 2LiF + I2

  9. Physical Science: Ch. 7, Sec. 4 Reaction Rates and Equilibrium • ____________________is the speed at which a reaction occurs. • It is based on _____________ ____________________________________________________

  10. Five factors that can increase reaction rate: ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________

  11. Physical Science: Reaction Rates and Equilibrium For some reactions, you can change the _____of reactions by using ____________. ___________are ____ reactants, but they change the ________ of a reaction by lowering necessary ______________(go faster).

  12. Catalyst terminology Catalysts that ___________chemical reactions are called _____________. Catalysts in ________and _________ that affect reaction rate (usually speeding it up) are called ______________.
