Types of Chemical Reactions

This set of flashcards covers the different types of chemical reactions and their definitions.

Chemical Reaction

A process in which two or more substances react to form one or more new substances with different properties.

Synthesis Reaction

A reaction where two or more simple substances combine to form a more complex substance (e.g., A + B —-> AB).

Decomposition Reaction

A reaction in which a complex substance breaks down into two or more simpler substances (e.g., AB —--> A + B).

Single Replacement Reaction

A reaction where an uncombined element replaces an element in a compound (e.g., AB + C —--> A + CB).

Double Replacement Reaction

A reaction where two compounds react to form two new compounds (e.g., AB + CD —---> AD + CB).

HgO—> Hg + O2

Decomposition

Al + O2 —→ Al2O3

Synthesis

HCI + NaOH —> NaCl + H2O

Single- displacement reaction

Pb(NO3)3 + K3CrO4 —> PbCrO4 + KNO3

Double-replacement reaction
