一、实验基础将充满NO2气体的试管倒立于水槽中(如右图),充分反应后,剩余气体(NO)与适量O2恰好完全反应,生成的NO2气体再与水反应,……,如此多次实验。假设每次反应都没有气体损失,试推导出NO2与水反应的次数与试管内液面上升的高度之间的关系,并判断液体能否充满试管(理论推断)。二、理论依据基本反应:3NO2+H2O2HNO3+NO(1)2NO+O First, the experimental foundation will be filled with NO2 gas tube upside down in the sink (as shown), after sufficient reaction, the remaining gas (NO) and the right amount of O2 just exactly the reaction, the generated NO2 gas reacts with water ... ..., so much Experiment. Assuming that there is no gas loss for each reaction, the relationship between the number of times NO2 reacts with water and the height of the liquid level in the test tube is deduced and it is judged whether the liquid can fill the test tube (theoretical inference). Second, the theoretical basis of the basic reaction: 3NO2 + H2O  2HNO3 + NO (1) 2NO + O 
