化学实验作为学习的一种方式,它的认知功能与方法功能是非常有价值的。阿伏加德罗定律蕴含丰富实验内涵,本文通过对阿伏加德罗定律的实验归纳,提升科学分析能力。类型一、验证阿伏加德罗定律例1为验证:“同温同压下,相同体积的任何气体都含有相同的数目的分子”。查阅资料:HCl和NH_1均不溶于石蜡油,也不与之反应。该小组同学设计了如图所示的装置,图中B管的容积是A管的2倍, As a way of learning, chemistry experiment is very valuable in its cognitive function and method function. Avogadro’s law contains a wealth of experimental connotation. In this paper, through the experimental induction of Avogadro’s Law, the ability of scientific analysis is improved. Type 1, Verify Avogadro’s Law Example 1 To verify that: “With the same temperature and pressure, the same volume of any gas contains the same number of molecules ”. Access to information: HCl and NH_1 are not soluble in paraffin oil, nor with the reaction. The group of students designed the device shown in Figure B tube volume is 2 times the A tube,
