1. Make sure you turned in your rxn rate vocab, 11.2 vocab, & 11.2 Guided reading to class tray.

2. Get out paper for notes and answer the following question: What are the different types of reac

tions?

I II III IV V

Chemical Reactions

Types of Chemical Reactions

A. Synthesis

the combination of 2 or more substances to form a compound

only one product

A + B AB

A. Synthesis

H2(g) + Cl2(g) 2 HCl(g)

B. Combustion

CH4(g) + 2O2(g) CO2(g) + 2H2O(g)

the burning of any substance in O2 to produce heat

A + O2 B

EX: Burning of natural gas, wood and gasoline

C. Decomposition

a compound breaks down into 2 or more simpler substances

only one reactant

AB A + B

C. Decomposition

2 H2O(l) 2 H2(g) + O2(g)

D. Single Replacement one element replaces another in a compound

metal replaces metal (+) nonmetal replaces nonmetal (-) Halogens are replaced by a more reactive

halogen

A + BC B + AC

D. Single Replacement

Cu(s) + 2AgNO3(aq) Cu(NO3)2(aq) + 2Ag(s)

AB + CD AD + CB

E. Double Replacement

ions in two compounds “change partners” cation of one compound combines with

anion of the other

E. Double Replacement

Pb(NO3)2(aq) + K2CrO4(aq) PbCrO4(s) + 2KNO3(aq)
