Types of Chemical Reactions

Vocabulary flashcards covering the definitions and examples of combination, decomposition, thermal decomposition, and photolysis reactions from the lecture notes.

Combination reaction

Reactions in which two or more reactants combine to form one product, represented by the general equation $A + B \rightarrow AB$.

Decomposition Reaction

Reactions in which one compound decomposes into two or more compounds or elements, represented by the general equation $AB \rightarrow A + B$.

Relationship between Combination and Decomposition Reactions

A decomposition reaction is considered the exact opposite of a combination reaction.

Decomposition of Calcium carbonate

A reaction where calcium carbonate decomposes into calcium oxide and calcium dioxide.

Thermal decomposition

The decomposition of a substance that occurs specifically upon heating.

Lead Nitrate Thermal Decomposition Equation

The decomposition of lead nitrate represented in the notes as $2Pb(NO_{3})_{2}(s) \rightarrow 2PbO(s) + 4NO_{2}(g) + O_{2}(g)$.

Photolysis (Photo Decomposition)

Reactions in which a compound decomposes because of exposure to sunlight.

Photolysis of Silver chloride

A specific reaction where silver chloride is put in sunlight and decomposes into silver metal and chlorine gas.
