Types of Reactions The Six Different Types of

Types of Reactions

The Six Different Types of Reactions • Synthesis Reaction • Decomposition Reaction • Single Replacement Reaction • Double Replacement Reaction • Combustion Reaction • Oxidation-Reduction Reaction

Synthesis Reaction • A reaction where two or more substances react to produce one substance • The reactants can be either elements or compounds • A + B AB

Synthesis Reaction A B 2 Na + Cl 2 2 Na. Cl

Decomposition Reaction • A reaction in which a compound breaks down into two or more simpler substances • The products may be elements or compounds • AB A + B

Decomposition Reaction A B 2 H 2 O 2 H 2 + O 2

Single Replacement Reaction • A reaction in which one element takes the place of another element in a compound A + BC B + AC

Single Replacement Reaction A B C B A C 2 K + 2 H 2 O H 2 + 2 KOH The Potassium (K) replaces the Hydrogen in water (H 2 O) to form Potassium Hydroxide (KOH)

Double Replacement Reaction • A reaction in which two different compounds exchange ions and create two new compounds AB + CD AD CB

Double Replacement Reaction A B CD AD C B Ca. CO 3 + 2 HCl Ca. Cl 2 + H 2 CO 3

Combustion Reaction • A reaction in which a substance reacts rapidly with oxygen • This often producing heat and light • Combustion reactions usually produce a compound + H 2 O

Combustion Reaction • Methane reacting with oxygen to produce Carbon Dioxide and H 2 O CH 4 + 2 O 2 CO 2 + 2 H 2 O

Oxidation - Reduction • Oxidation – Reduction reactions involve an atom or molecule losing or gaining an electron • Usually involves a metal and oxygen

Oxidation - Reduction • The Oxidation-Reduction reaction between Iron and Oxygen is often known as Rust
