11.2 CLASSIFICATIONS
OF CHEMICAL REACTIONS
Why do we classify things?
TYPE #1 _________________ _______________
___________ + __________ → ____________
Also, element + compound → compound
compound + compound → compound
If there is a ________________ _______________, assume it is a synthesis reaction!
Rusting 4Fe + 3O2 → 2 Fe2O3
Here’s another type of reaction
___C3H5N3O9 →
___N2 + ___CO2 + ___H2O + __O2
Click
TYPE #3 ________________________
___NH3 → ___N2 + ___H2
___KClO3 → ___KCl + ___O2
___PbCO3 → __PbO + ___CO2
If there is a _____________________, assume it is a decomposition reaction!
2H2 + O2 → 2H2OThis is a synthesis reaction; it’s also a
_____________________reaction, which is a chemical change in which an element or product
reacts with ___________often producing
__________ & _________
This is TYPE #3. Think ___________________!One of the world’s most important chemical
reactions of all is the combustion of a
_______________________
This is the COMPLETE COMBUSTION of a hydrocarbon…
MEMORIZE THIS GENERIC EQUATION!
Type #4 ____________________________
___ Pb + ___ H2SO4 → ___ PbSO4 + ___H2
___ K2Cr2O7 + ___ AgNO3 →___KNO3 + ___Ag2Cr2O7
___HCl + ___ NaOH → ___NaCl + ___HOH Click
Classify these reactions:
a. ___NH4 NO3 → ___ N2O + ___ H2O
b. ___ Li + ___ FeSO4 → ___ Fe + Li2SO4
c. ___ C2H6 + ___ O2 → ___ CO2 + ___ H2 O
d. ___ Al + ___ F2 → ___ AlF3
e. ___ CuCl2 + ___ Na3PO4 → ___ Cu3PO4 + __ NaCl
