Combustion of Hydrocarbons

CxHyOz --> H2O + CO2

Double Displacement

AB + CD --> AD + BC

Single Displacement

A + BC --> AC + B

Decomposition

AB --> A+B
1 reactant

Synthesis

A+B --> AB
1 product

Characteristics of a chemical reaction

1. The equation must represent all known facts: H2O2 (l) → H2O (l) + O2 (g)
2. The equation must contain the correct formulas for the reactants or the products
3. The law of conservation of mass must be satisfied → 2H on left → 2H on right

Indications of a chemical reaction

1. Production of heat or light
2. Production of a gas
3. Formation of a precipitate (an insoluble solid produced in a reaction)

Rule 6

All compounds containing PO4(3-), S(2-), CO3(2-) and SO3(2-) are insoluble except those that also contain alkali metals or NH4(+)

Rule 5

All hydroxides are insoluble except compounds of the alkali metals, Ca(2+), Sr(2+), and Ba(2+)

Rule 4

All sulfates are soluble except those containing Hg(2+), Pb(2+), Sr(2+), Ca(2+) or Ba(2+)

Rule 3

All chlorides, bromides, and iodides are soluble except those containing Ag(+) Pb(2+) or Hg(2+)

Rule 2

All compounds containing NO(3-), ClO4(-), ClO3(-), and C2H3O2 (-) anions are soluble

Rule 1

All compounds containing alkali metal cations and the ammonium ion are soluble
