Sulfuric acid and sodium hydroxide
react to produce sodium sulfate and
water.
Day 4
9-17
1. How
do I use an equation to
represent a chemical reaction?
2. How do I classify different types of
rxns.?
Day 3 9-14
Single-Replacement
Types of Chemical Equations
Reactions
Single-replacement reaction OR
displacement reaction – one element
replaces a similar element in a compound.
A + BX
AX + B
Y + BX
BY + X
A, B, X, and Y = eles.;
AX, BX, and BY = cmpds.
Example: Fe(s) + CuSO4(aq)
A
BX
FeSO4(aq) + Cu(s)
AX
B
Single-replacement
Types of Chemical Equations
Reactions
Examples:
- a metal with another metal
- H in water with a metal
- H in an acid with a metal
- Halogens ***

Double-replacement
Types of Chemical Equations
Reactions
Double-replacement reactions – the ions of
2 cmpds. exchange places in an aqueous
sltn. to form 2 new cmpds.

Reactions
Equations
Combustion reactions – a substance
combines with oxygen, releasing a large
amount of energy (light or heat)
Unique equations
Examples:
Hydrogen gas: 2H2(g) + O2(g)
Propane: C3H8(g) + 5O2(g)
2H2O(g)
3CO2(g) + 4H2O(g)
