  1. REACTIONS STUDY GUIDE List the 5 types of reactions and give a brief definition of each: (10 points) COMPOSITION A + Y --> AY FEWER PRODUCTS DECOMPOSTION AY --> A + Y MORE PRODUCTS

  2. REACTIONS STUDY GUIDE List the 5 types of reactions and give a brief definition of each: (10 points) SINGLE REPLACEMENT A + BY --> B + AY ONE ELEMENT REPLACES ANOTHER IN A COMPOUND DOUBLE REPLACEMENT AY + BZ --> AZ + BY TWO ELEMENTS SWITCH POSITIONS

  3. REACTIONS STUDY GUIDE List the 5 types of reactions and give a brief definition of each: (10 points) COMBUSTION AY + O2 --> AO + YO TWO REQUIREMENTS: 1. ADD ELEMENTAL OXYGEN 2. BOTH OXYGEN AND COMPOUND BREAK UP ** COULD ALSO BE: ABX + O2 --> AO + BO + XO

  4. REACTIONS STUDY GUIDE Which two types of reactions are almost exactly opposite of each other? _______________________ & _______________________ COMPOSITION DECOMPOSITION

  5. REACTIONS STUDY GUIDE Which two types of reactions have the same number of reactants and products? ________________________ & ________________________ SINGLE REPLACEMENT DOUBLE REPLACEMENT

  6. REACTIONS STUDY GUIDE Where are the products found in relation to the arrow? Where are the reactants found in relation to the arrow? Point or Tail ? Point or Tail ?

  7. Identify the following type of reactions: 1) ZnCl2 + HBr --> HCl + ZnBr2 REACTIONS STUDY GUIDE AY + BZ --> AZ + BY DOUBLE REPLACEMENT 2) Cr + NiO --> Ni + Cr2O3 A + BZ --> B + AZ SINGLE REPLACEMENT

  8. Identify the following type of reactions: 3) Ba + (PO4) --> Ba3(PO4)2 REACTIONS STUDY GUIDE A + Y --> AY COMPOSITION 4) CH4 + O2 --> CO2 + H2O AY + O2 --> AO + YO COMBUSTION

  9. Identify the following type of reactions: Ra(CO3) --> RaO + CO2 REACTIONS STUDY GUIDE AY --> A + Y DECOMPOSITION FeS + O2 --> Fe2O3 + SO2 AY + O2 --> AO + YO COMBUSTION

  10. List the three proper places to add a line to balance any given reaction: 1) At the very beginning. (All the way to the left) REACTIONS STUDY GUIDE 2) After any “+” sign. (to the right of any one) 3) After the arrow. (to the right of the arrow)

  11. REACTIONS STUDY GUIDE BALANCE THE FOLLOWING REACTIONS: __ ZnCl2 + __ HBr --> __ HCl + __ ZnBr2 1 2 2 1 2 3 3 1 __ Cr + __ NiO--> __ Ni + __ Cr2O3 3 2 1 __ Ba + __ (PO4) --> __ Ba3(PO4)2 __ CH4 + __ O2 --> __ CO2 + __ H2O 1 2 1 2 __ Ra(CO3) --> __ RaO + __ CO2 1 1 1

  12. REACTIONS STUDY GUIDE BALANCE THE FOLLOWING REACTIONS: 4 / 4 / __ FeS + __ O2 --> __ Fe2O3 + __ SO2 2 7 2 2 1 2 1 1 __ Mg(SO4) + __ NaCl --> __ Na2(SO4) + __ MgCl2 2 1 1 1 __ HCl + __ BaO --> __ H2O + __ BaCl2 1 3 2 3 __ Ba3(PO4)2 + __ H2S --> __ H3(PO4) + __ BaS 1 1 1 1 __ NaOH + __ HCl --> __ NaCl + __ H2O

  13. REACTIONS STUDY GUIDE Reactants (define in relationship to arrow): Elements and compounds at the FLAT of the arrow. Products (define in relationship to arrow): Elements and compounds at the POINT of the arrow. Yields THE ARROW

  14. REACTIONS STUDY GUIDE List the three proper places to place a line for balancing reactions. 1) 2) 3) At the very beginning After every plus sign (“+” sign) After the arrow (-->)

  15. REACTIONS STUDY GUIDE • 25 points for side #1 • 44 points for side #2 • Make sure your name is preceded by CB: (You do get credit for this!) • Place on a pile on my desk.
