Prova:UEPB 2009
Disciplina:Química
Assunto:Grandezas: massa, volume, mol, massa molar, constante de Avogadro e Estequiometria., Representação das transformações químicas
O principal produto da reação apresentada na Equação A é o isômero
p,p’-DDT. Um químico tratou uma amostra de DDT de modo a obter
apenas esse isômero. Em seguida foi feita uma análise elementar de
cloro e foi encontrado 1,75 mol de Cl para cada mol de clorobenzeno
consumido. Qual o rendimento da reação de formação desse isômero?

TEXTO 2
Durante décadas, o DDT(dicloro-difenil-tricloroetano) foi
largamente usado como inseticida até ser comprovado que, além de
provocar câncer, demora de 4 a 30 anos para se degradar. O DDT foi
utilizado na Segunda Guerra Mundial para prevenção de tifo em
soldados, que o utilizavam também para o combate a piolhos.
Posteriormente foi usado na agropecuária, no Brasil e no mundo,
dado seu baixo preço e elevada eficiência. Especialistas afirmam que
o principal problema do DDT é sua ação indiscriminada, que atinge tanto as pragas quanto o resto da fauna e flora da área afetada. O
DDT também se infiltra na água, contaminando os mananciais.
Uma forma de preparação do DDT é o aquecimento de
clorobenzeno e cloral hidratado, em presença de ácido sulfúrico.

Durante décadas, o DDT(dicloro-difenil-tricloroetano) foi largamente usado como inseticida até ser comprovado que, além de provocar câncer, demora de 4 a 30 anos para se degradar. O DDT foi utilizado na Segunda Guerra Mundial para prevenção de tifo em soldados, que o utilizavam também para o combate a piolhos. Posteriormente foi usado na agropecuária, no Brasil e no mundo, dado seu baixo preço e elevada eficiência. Especialistas afirmam que o principal problema do DDT é sua ação indiscriminada, que atinge tanto as pragas quanto o resto da fauna e flora da área afetada. O DDT também se infiltra na água, contaminando os mananciais.
Uma forma de preparação do DDT é o aquecimento de
clorobenzeno e cloral hidratado, em presença de ácido sulfúrico.
