实验中注意安全是至关重要的，回答下列有关问题。
（1）点燃H₂前需要检验H₂的      ；
（2）不慎将燃着的酒精灯碰倒，洒出的酒精燃烧，立即用湿抹布盖灭，利用了灭火原理中的降低温度和     ；
（3）做硫在氧气中燃烧的实验时，可用NaOH溶液吸收有毒的SO₂，产物是H₂O和能溶于水的Na₂SO₃，这一反应可用化学方程式表示为             。

根据金属的化学性质，将下表中内容补充完整

反应物	反应规律	反应规律的应用举例
金属+氧气	大多数金属能和O2反应生成金属氧化物	铝表面形成致密的氧化薄膜，阻止铝进一步氧化
金属+酸	在金属活动性顺序里，位于  ①  的金属能与盐酸、稀硫酸发生置换反应生成盐和H2	用盐酸和稀硫酸鉴别黄金和黄铜（铜锌合金）
金属+盐	在金属活动性顺序里，位于前面的金属能把位于后面的金属从它们的盐溶液里置换出来，生成  ②	将Cu、Mg、Zn中的两种金属分别放入  ③ 溶液中，即可比较出上述三种金属的活动性强弱

 

观察下列各图，回答有关问题

（1）仪器a的名称是        ；
（2）实验室制取CO₂，其反应原理可用化学方程式表示为   ①    ；其发生装置可选用上图中的  ②  （填装置序号，下同），收集装置可选用  ③  ；
（3）利用收集到的CO₂进行图E所示实验，观察到燃着的蜡烛自下而上依次熄灭，体现出CO₂的密度比空气大和      的性质。

回忆教科书中有关“粗盐的初步提纯”实验的主要步骤，回答下列问题。
【溶解】称取5.0g粗盐，用药匙将该粗盐逐步加入盛有10mL水的烧饼里，边加边用玻璃棒搅拌，直加到粗盐不再溶解为止。称量尚未向烧杯中加入的粗盐质量。
【过滤】……
【蒸发】……
【计算产率】用玻璃棒把提纯后的精盐转移到纸上，称其质量，计算精盐的产率。
精盐的产率＝×100%
（1）过滤时，玻璃棒的作用是         ；
（2）蒸发过程中，待蒸发皿中出现        固体时，停止加热，利用余热使滤液蒸干；
（3）某同学所得的产率与其他同学比较明显偏低，下列哪些情况会导致产率明显偏低        （选填字母序号）
A溶解时将5.0g粗盐一次全部倒入水中，立即过滤
B蒸发时有一些液体、固体溅出
