逻辑推理是学好化学的重要思维方法下面是从小明同学学习笔记中摘录出来的一些推理你认为正确的一句是
某化学兴趣小组同学查阅资料后发现有许多金属离子对双氧水的分解具有催化作用．为比较Fe3+和Cu2+两种离子对H2O2分解的催化效果他们分成甲乙两组分别设计了如图一图二所示的实验并进行了实验．设两种盐溶液的浓度等条件相同 1写出以FeCl3为催化剂的反应的化学方程式． 2要证明FeCl3为催化剂还要证明FeCl3的和不变． 3检查图二装置气密性的方法是填“打开”或“关闭”仪器A的活塞将注射器活塞拉出一定距离一段时间后松开活塞观察到活塞又回到了原位则说明装置气密性填“良好”或“不好”．该组同学利用图二所示实验需测量的数据是． A．一定时间内收集到的气体体积B．收集一定体积的气体所需双氧水的质量 4图一可通过观察产生气泡的快慢来定性比较得出结论．有同学提出将药品CuSO4改为CuCl2更为合理其理由是． 你认为药品还可以作何改进．
