Classifying Reactions
• Some general types of chemical reactions are synthesis reactions, decomposition reactions, single-replacement reactions, double-replacement reactions and combustion reactions

Synthesis Reaction
• A reaction in which two or more substances react to form a single substance.– Reactants may be either elements or compounds– Product is always a compound

Decomposition Reaction
• A reaction in which a compound breaks down into two or more simpler substances.– Reactant must be a compound– Products may be elements or compounds

Single Replacement Reaction
• A reaction in which one element takes the place of another element in a compound.

Double Replacement Reaction
• One in which two different compounds exchange positive ions and form two new compounds

Combustion Reaction
• One in which a substance reacts rapidly with oxygen, often producing heat and light.

Reactions as Electron Transfers
• A reaction in which electrons are transferred from one reactant to another is called an oxidation-reduction reaction, or redox reaction

Reactions as Electron Transfers
• Oxidation– Type of synthesis reaction, in which a metal
combines with oxygen• Reduction– Process in which an element gains electrons
during a chemical reaction– Reactant is said to be reduced if it gains electrons
• Oxidation and reduction always occur together
