化学方程式huàxué fāngchéngshì用化学式表明化学反应的式子。化学方程式中,反应物的化学式写在左边,生成物的化学式写在右边,中间用等号连接,各元素在两侧的原子数相等。如 N?+3H?=2NH?。{chemical equation; symbolic representation showing the type and amount of the elementary materials and products of a reaction in which the chemical formula of the elementary materials is on the left, and that of the product is on the right, with both connected by an equal sign, and having equal atomicity of each element on both sides, such as N?+3H?=2NH?}也叫also化学反应式{huàxué fǎnyìngshì}。简称{abbr.}方程式{fāngchéngshì}。 |
