初中化学第110页有这样一段话:“碳的各种同素异形体都有同样的化学性质。”许多资料表明,同素异形体不仅物理性质有很大的差异,就是化学性质也不尽相同。下面就以碳的同素异形体为例说明。碳的三种同素异形体,在空气或氧气中都能燃烧生成二氧化碳,这一点是相同的。但因它们的晶体结构不同,他们的化学性质也不尽相同。如金刚石在空气中要加热到777℃才能燃烧,石墨在空气中只要加热到687℃就能燃烧,而无定形碳在空中燃烧需要的温度更低。又如,金刚石不与一般的酸碱等化学物质作用,
On junior high school chemistry page 110, there is such a paragraph: “All kinds of carbon allotropes have the same chemical properties.” Many data indicate that allotropes have not only large differences in physical properties, but also chemical properties. the same. Here is an example of a carbon allotrope. All three carbon allotropes can burn in air or oxygen to produce carbon dioxide, which is the same thing. However, due to their different crystal structures, their chemical properties are not the same. If diamonds are heated in the air to 777°C to burn, graphite can be burned in air as long as it is heated to 687°C, whereas amorphous carbon requires less temperature to burn in the air. In another example, diamonds do not interact with normal chemicals such as acids and alkalis.
