高中课本中,铝箔在氧气中燃烧的实验很难成功。经我们多次实验得知,此实验成功的关键有两点。1.铝箔要薄,可用香烟盒或纸质电容器内的铝箔。2.当被铝箔卷住的火柴燃烧最旺时,再插入集气瓶内。具体做法:先用一片铝箔(3 cm×5 cm)卷住一根
In high school textbooks, experiments with aluminum foil burning in oxygen are difficult to succeed. As we have learned from many experiments, the key to the success of this experiment is twofold. 1. Aluminum foil should be thin, available in cigarette packs or aluminum foil in paper capacitors. 2. When the match that is wrapped in aluminum foil is burning the most, insert the gas cylinder again. Specific approach: first use a piece of aluminum foil (3 cm × 5 cm) to roll a
