Neste tipo de reacao um unico composto e obtido a partir de dois compostos. Vamos ver uma ilustracao deste tipo de reacao! Vamos ver alguns exemplos?Como o proprio nome diz, este tipo de reacao e o inverso da anterior (composicao), ou seja, ocorrem quando a partir de um unico composto sao obtidos outros compostos. Estas reacoes tambem sao conhecidas
