Responda
(UFRN)O nitrogênio forma vários óxidos binários apresentando diferentes números de oxidação: NO (gás tóxico), N2O (gás anestésico - hilariante), NO2 (gás avermelhado, irritante), N2O3 (sólido azul) etc. Esses óxidos são instáveis e se decompõem para formar os gases nitrogênio (N2) e oxigênio (O2). O óxido binário (NO2) é um dos principais poluentes ambientais, reagindo com o ozônio atmosférico (O3) - gás instável - responsável pela filtração da radiação ultravioleta emitida pelo Sol. Baseando-se nas estruturas desses óxidos, pode-se concluir que a fórmula molecular em que o átomo de nitrogênio apresenta o menor número de oxidação é: a. ( ) N2O3. b. ( ) NO. c. ( ) N2O. d. ( ) NO2.Resposta:c

(UFU-MG) O dióxido de cloro vem substituindo o cloro (Cℓ2) em muitas estações de tratamento de água para abastecimento público de países desenvolvidos, pois investigações em laboratório têm mostrado que o Cℓ2, na presença de matéria orgânica, pode produzir compostos organoclorados, altamente tóxicos. O dióxido de cloro pode ser obtido pela reação entre clorito de sódio e Cℓ2, de acordo com: 2NaCℓO2(s) + Cℓ2(g) → 2NaCℓ(s) + 2CℓO2(g) O estado de oxidação do cloro nos compostos NaCℓO2, Cℓ2, NaCℓ e CℓO2 é, respectivamente, a) – 1, 0, – 1 e + 2 b) + 1, – 1, 0 e – 4 c) + 1, – 1, 0 e – 4 d) + 3, 0, – 1 e + 4Resposta:c
