1、NaOH+HCl=NaCl+H2O,则10gNaOH完全反应所生成的水的质量为( )。
A.4g B.4.5g C.5g D. 5.5g
【知识点】化学反应及及其能量变化
【答案】
B
2、下列实验装置或操作设计正确且能达到实验目的的是( )
【知识点】物质的分离 提纯和检验
【答案】
C
3、足量的铝分别与等物质的量浓度的稀盐酸、氢氧化钠溶液反应,放出的气体在标准状况下体积相等,则所取稀盐酸和氢氧化钠溶液的体积比为( )
A. 3:1 B. 3:2 C. 1:2 D. 6:1
【知识点】碱金属单元测试
【答案】
考点: 化学方程式的有关计算.
分析: 发生反应:2Al+6HCl=AlCl3+3H2↑,2Al+2NaOH+2H2O=2NaAlO2+3H2↑,产生相同物质的量的氢气时,则n(HCl):n(NaOH)=6:2=3:1,因为物质的量浓度相同,因此消耗的HCl、NaOH的体积之比等于其物质的量之比.
解答: 解:发生反应:2Al+6HCl=AlCl3+3H2↑,2Al+2NaOH+2H2O=2NaAlO2+3H2↑,产生相同物质的量的氢气时,则n(HCl):n(NaOH)=6:2=3:1,因为物质的量浓度相同,因此消耗的HCl、NaOH的体积之比:v(HCl):v(NaOH)=n(HCl):n(NaOH)=3:1,
故选:A.
点评: 本题考查物质的量在化学反应方程式计算中的应用及金属铝的性质,有利于基础知识的巩固.
