已知2NO2+2NaOH==NaNO2+NaNO3+H2O ,NO+NO2+2NaOH==2NaNO2+H2O 下列气体中不可能被过量NaOH溶液完全吸收的A.1 mol O2和4 mol NO2 B.1 mol NO和4 mol NO2 C.1 mol O2和4 mol NO D.4 mol NO和1 mol NO2

已知2NO2+2NaOH==NaNO2+NaNO3+H2O ,NO+NO2+2NaOH==2NaNO2+H2O 下列气体中不可能被过量NaOH溶液完全吸收的A.1 mol O2和4 mol NO2 B.1 mol NO和4 mol NO2 C.1 mol O2和4 mol NO D.4 mol NO和1 mol NO2
已知2NO2+2NaOH==NaNO2+NaNO3+H2O ,NO+NO2+2NaOH==2NaNO2+H2O 下列气体中不可能被过量NaOH溶液完全吸收的
A.1 mol O2和4 mol NO2 B.1 mol NO和4 mol NO2
C.1 mol O2和4 mol NO D.4 mol NO和1 mol NO2

已知2NO2+2NaOH==NaNO2+NaNO3+H2O ,NO+NO2+2NaOH==2NaNO2+H2O 下列气体中不可能被过量NaOH溶液完全吸收的A.1 mol O2和4 mol NO2 B.1 mol NO和4 mol NO2 C.1 mol O2和4 mol NO D.4 mol NO和1 mol NO2
已知：2NO2+2NaOH==NaNO2+NaNO3+H2O ①,
NO+NO2+2NaOH==2NaNO2+H2O②
又：2NO+O2=2NO2
则：2NO+O2+2NaOH==NaNO2+NaNO3+H2O ,③
先看B项：1 mol NO和4 mol NO2 中,由②可知,先是1mol NO和1mol NO2与氢氧化钠反应,又由 ①可知：剩下的NO2 可完全被吸收
C项：1 mol O2和4 mol NO 中,由,③可知,先是1 mol O2和2 mol NO 与氢氧化钠反应,又由
①可知：剩下的NO2 可完全被吸收
D项：4 mol NO和1 mol NO2中,由②可知,先是1mol NO和1 mol NO2,剩余的NO既不与H2O反应,又不能单独与氢氧化钠反应,所以选D
BUT,
A项我不太确定,如果按4NO+O2+2H2O==4HNO,那么就不能选A； 但是老师有说过物质是先和溶质反应,后和溶剂反应,那么NO2就应和氢氧化钠反应完了,剩有O2
若是多选,选AD；单选选D,
