1.“绿色化学”是指从技术、经济上设计可行的化学反应,尽可能减少对环境的负作用。下列化学反应,不符合绿色化学概念的是A.消除硫酸厂尾气排放SO_2+NH_3+H_2O=(NH_4)_2SO_3 B.消除制硝酸工业尾气的氮氧化物污染NO_2+NO+NaOH=2NaNO_2+H_2OC.制CuSO_4:Cu+2H_2SO_4(浓)
1. “Green chemistry” refers to designing feasible chemical reactions technically and economically to minimize negative effects on the environment. The following chemical reactions that did not meet the concept of green chemistry were: A. Elimination of tail gas emissions from sulfuric acid plants SO_2+NH_3+H_2O=(NH_4)_2SO_3 B. Elimination of nitrogen oxide pollution from nitric acid industrial tail gas NO_2+NO+NaOH=2NaNO_2+H_2OC. CuSO_4: Cu+2H_2SO_4 (concentrated)
