Classifying Chemical Reactions 10.2 Classifying Chemical Reactions

A + B  AB Fe + Cl2  FeCl2 Synthesis RXN

Synthesis RXN 2 or more compounds to make 1 product More reactants than products 2 elements 1 element + 1 compound 2 compounds Synthesis RXN

AB  A + B 2NH4NO3  2N2 + O2 + 4H2O Decomposition RXN

One compound breaks down into 2 or more elements or simpler compounds More products than reactants Usually require ENERGY (E) to get started Decomposition RXN

Single Replacement RXN Ax + B  Bx + A 2Zn + 2HCl  2ZnCl + H2 Single Replacement RXN

Single Replacement RXN 1 reactant switches places with another 1 substance is displaced Single Replacement RXN

Double Replacement RXN Ax +By  Ay + Bx NaOH + HCl  NaCl + H2O Double Replacement RXN

Double Replacement RXN 2 substances switch places Always forms Precipitate Gas H2O Double Replacement RXN

A + O2  AOx 2H2 + O2  2H2O Combustion RXN
