Types of Chemical Reactions 11 th Grade Honors Chemistry

Synthesis Reactions • A synthesis reaction occurs when two or more reactants combine to form a single product. • A+B C

Synthesis Reaction Examples

Decomposition Reactions • One reactant breaks down into two or more products. It is the reverse of a synthesis reaction. AB A+B

Decomposition Reaction Examples

Replacement Reactions • Elements switch places in compounds. • In a single replacement reaction, one element takes the place of another in a single compound. • In a double replacement reaction, two compounds exchange elements.

Replacement Reaction Examples

Combustion Reactions • When a substance reacts quickly with oxygen. • Combustion is commonly called “burning”. • Carbon Dioxide, water, and heat/light (it escapes) are all products of combustion.

Combustion Reaction Examples

Using your worksheet please fill in the missing information. A = Red B = Blue C = Green D = Yellow Type of Reaction Synthesis Definition Equation Two or more elements or compounds combine to make a more complex substance A + B → AB AB → A + B Decomposition Compounds break down into simpler substances Single Replacement Occurs when one element replaces another one in a compound AB + C → AC + B Double Replacement Occurs when different atoms in two different compounds trade places AB + CD → AC + BD
