11.2 CLASSIFICATIONS OF CHEMICAL REACTIONS

1. 11.2CLASSIFICATIONSOF CHEMICAL REACTIONS

2. Why do we classify things?

3. TYPE #1 _________________ __________________________ + __________ → ____________ Also, element + compound → compound compound + compound → compound If there is a ________________ _______________, assume it is a synthesis reaction!

4. Rusting 4Fe + 3O2 → 2 Fe2O3

5. Here’s another type of reaction___C3H5N3O9 → ___N2 + ___CO2 + ___H2O + __O2Click

6. TYPE #3 ________________________

7. ___NH3 → ___N2 + ___H2 ___KClO3 → ___KCl + ___O2 ___PbCO3 → __PbO + ___CO2If there is a _____________________, assume it is a decomposition reaction!

8. 2H2 + O2 → 2H2O This is a synthesis reaction; it’s also a _____________________ reaction, which is a chemical change in which an element or product reacts with ___________often producing __________ & _________

9. This is TYPE #3. Think ___________________!One of the world’s most important chemical reactions of all is thecombustion of a

10. _______________________This is the COMPLETE COMBUSTION of a hydrocarbon… MEMORIZE THIS GENERIC EQUATION!

11. Type #4 _______________________________ Pb + ___ H2SO4 → ___ PbSO4 + ___H2

12. ___ K2Cr2O7 + ___ AgNO3 →___KNO3 + ___Ag2Cr2O7 ___HCl + ___ NaOH → ___NaCl + ___HOHClick

13. Classify these reactions:a. ___NH4 NO3 → ___ N2O + ___ H2Ob. ___ Li + ___ FeSO4 → ___ Fe + Li2SO4 c. ___ C2H6 + ___ O2 → ___ CO2 + ___ H2 Od. ___ Al + ___ F2 → ___ AlF3 e. ___ CuCl2 + ___ Na3PO4 → ___ Cu3PO4 + __ NaCl
