NO2and O3pathways under low-temperature and high-ionic strength conditions revealed no apparent formation of sulfate (Supplementary Fig.8). The sulfate formation rate was no more than the room temperature aqueous phase reaction rate, and the ionic strength effect on the NO2pathway was almost ...
向一定质量AgNO3和Cu(NO3)2的混合溶液中加入过量的Zn粉时,锌先和硝酸银反应生成硝酸锌和银,反应过程中溶液质量减小,故a点溶液中溶质质量分数和原混合溶液相比将变小;(1)当硝酸银完全反应后,故图标上b−d段:锌再和硝酸铜反应生成硝酸锌和铜,反应过程中,溶液质量增大。故填:锌再和硝酸铜反应生成硝酸锌和铜。(...
