1、毛坦厂中学2024~2025学年度第二学期高一期中考试(25-T-660A) 试题


(1)2个镁原子  2Mg  。
(2)3个铝离子  3Al3+  。
(3)标出二氧化碳中碳元素的化合价  O2  。
(4)铁丝在氧气中燃烧的化学方程式  3Fe+2O2Fe3O4  。
【解答】解:(1)原子的表示方法就是用元素符号来表示一个原子,表示多个该原子,就在其元素符号前加上相应的数字.所以2个镁原子,就可表示为:2Mg;
(2)离子的表示方法:在表示该离子的元素符号右上角,标出该离子所带的正负电荷数,数字在前,正负符号在后,带1个电荷时,1要省略.若表示多个该离子,就在其元素符号前加上相应的数字,故3个铝离子可表示为:3Al3+;
(3)元素化合价的表示方法:确定出化合物中所要标出的元素的化合价,然后在其化学式该元素的上方用正负号和数字表示,正负号在前,数字在后,所以标出二氧化碳中碳元素的化合价可表示为:O2;


C.反应前后元素的化合价不变
D.生成物的质量比为22:1
8科学控制和利用燃烧,对人类的生活和生产意义重大,下列说法错误的是
A.实验室酒精灯失火立即用湿抹布盖灭
