我们每天的生活都被化学现象所充斥着.有时候很容易去发现,比如你在教室里面做科学实验的时候.但有时候我们又很难去发现工作中的化学现象,但是其实不管你看到还是用到的东西几乎都有化学元素在里面.比如哪怕像牙膏这么简单的东西都有至少三种化学成分,甚至更多.牙膏就是这些化学成分的混合物,而就是因为这些化学反应才能使你的牙齿变白变干净.其他你每天可以用到的东西也是化学成分组成,比如洗发产品,香波或者肥皂.加入洗涤剂的水中也有化学成分.没有化学,我们就永远不知道原来肥皂可以洗掉我们衣服上或者皮肤上的油.
英语翻译We're surrounded by chemistry in everyday life.Sometimes
