在讲高一第六章第H节NZ这节课时,由于无实验内容,使学和教深感乏味,为此建议派补两个可做的简易实验内容,以增加学生学习化学的情趣.以下是两个实验的内容.实验一:氮气跟某些金属的反应.实验用品:集气瓶、玻片、火柴、镁条、镊子.实验操作:将点着的三支火柴放入空集
When we talk about the NZ chapter in the sixth chapter, section H, section NZ, because there is no experimental content, which makes learning and teaching deeply boring, it is proposed to fill two simple experiments that can be done to increase students’ interest in learning chemistry. The following are the contents of two experiments. Experiment 1: Nitrogen reaction with certain metals. Experimental supplies: gas cylinders, slides, matches, magnesium sticks, wolfberry. Experimental operation: Putting three matches at random into the empty set
