TYPES OF CHEMICAL REACTIONS (pg 1 of 4)
Name: ______________________
For each page, you must do the following THREE (3) things:
1) BALANCE each equation so that it does not violate the law of conservation of matter
2) Identify the TYPE of REACTION for each question (see below)
3) Provide the NAME (Nomenclature) for one reactant and one product
(if there is more than one reactant/product, you can chose which one you want to do – but one each)
1) SYNTHESIS (S) -(also called combination)
HINT- You can identify synthesis reactions easily because they only have one product.
General form:
X + Y
 XY
Examples: 2 H2 (g) + O2 (g)  2 H2O (g) (note only one product)
H2 (g) + Cl2 (g)  2HCl (g) (note only one product)
2) DECOMPOSITION (D) -(also called metathesis)
HINT- Decomposition is the opposite of synthesis. These reactions only have one reactant.
General form: XY  X + Y
Examples: 2NH3 (g)  N2 (g) + 3H2 (g) (note only one reactant)
2 Ag2O (s)  4 Ag(s) + O2 (g) (note only one reactant)
3) SINGLE REPLACEMENT (SR) -(also called single displacement)
HINT- The reactant will have a single element, and the product will have a different single element
General form:
A + BC
 B
+ AC
(element A  element B)
Examples: Mg (s) + 2HCl (aq)  MgCl2 (aq) + H2 (g) (Mg is the element  H2 is the element)
Li (s) + AgI (aq)  LiI (aq) + Ag (s)
(Li is the element  Ag is the element)
4) DOUBLE REPLACEMENT (DR) -(also called double displacement)
HINT- In double replacement reactions, two compounds react and trade partners.
General form: AB
+
CD
 AD + BC (A was with B  A is now with D)
Examples: HCl (aq) + NaOH (aq)  H2O (l) + NaCl (aq) (Na with NaOH Na with NaCl)
Na2CO3 (aq) + CaCl2 (aq) 2NaCl (aq) + CaCO3 (s)
(Na with Na2CO3  Na with NaCl) and (Ca with CaCl2  Ca with CaCO3)
**COMBUSTION (C) -(Burning something in the presence of oxygen – NOTE: Heat or Flame is required)
HINT- You can identify combustion if there is a FLAME and Oxygen (O2) is a reactant.
General form:
X + O2
 XO or XY + O2  XO + YO
Examples: 4 Al (s) + 3 O2 (g)  2 Al2O3 (g) (note that oxygen (O2) is present)
2 C6H6 (l) + 15 O2 (g)  12 CO2 (g) + H2O (g) (note that oxygen (O2) is present)
EXAMPLE: 1) Balance the equation, 2) Type of Reaction, and 3) Name one product and one reactant
