KCl+Na=NaCl+K↑推出K+ 的氧化性比Na+强为什么错
etc显示na是什么意思?
韩语na la是什么意思
jia房产证办理信用卡好办吗??信用卡中心会不会去核查呢?
解: KCl(l)+Na(l)=(可逆)NaCl(l)+K(g)
当反应温度控制在K和Na的沸点之间(K的沸点比Na低)时,K不断气化脱离反应体系,平衡向右移动。
这个反应是工业制取K的反应,在高温(反应物熔融)条件下进行,非溶液反应,不能以此作为依据得到K+的氧化性比Na+强的结论。
etc显示na是什么意思?意思就是不显示金额,储蓄卡可以通过ATM查询余额,但收费站刷卡设备上是无法显示余额的。目前高速公路收费处,有专门的ETC收费通道。车主只要在车辆前挡风玻璃上安装感应卡并预存费用,通过收费站时便不用人工缴费,也无须停车,高速通行费将从卡中自动扣除,即能够实现自动收费。
这种收费系统每车收费耗时不到两秒,其收费通道的通行能力是人工收费通道的5至10倍。
韩语na la是什么意思是 さようなら 吧
再见的意思
罗马音是:sa yo u na ra
有什么不懂得再补充吧
