2. (2013奉贤区二模)在图(a)所示的电路中,电阻R1的阻值为20欧,变阻器R2标有“20Ω 2A”字样,闭合电
(1)电阻来R1的电压U1=I1R1=0.3A×20Ω=6V,
电阻R1与自R2并联,接在电源两端,所以电源电压U=U2=U1=6V;
答:电源电压是6V.
(2)由电路图知,电流表A1测支路R1电流,电流表A2测干路电流,
由题意可判断得出:图b所示电流表是串联在干路上的电流表A2,
且示数为I=0.7A,所以流过电阻R2的电流I2=I-I1=0.7A-0.3A=0.4A,
滑动变阻器接入电路的阻值R2=
U2 |
I2 |
6伏 |
0.4安 |
3. (2013奉贤区二模)为了探究二氧化硫的漂白作用到底是二氧化硫本身还是二氧化硫与水作用的产物,某学习
(1)该实验是探究干燥的SO2能不能使品红褪色,所以二氧化硫通入品红溶液前要进行干燥;二氧化硫有毒,所以多余气体不能直接排空,故要有尾气处理装置,
故答案为:①二氧化硫没有干燥(或缺少二氧化硫的干燥装置);②没有尾气吸收装置;
(2)二氧化硫和水反应生成亚硫酸,SO2+H2O?H2SO3,亚硫酸是二元弱酸,所以能发生两步电离,第一步生成氢离子和亚硫酸氢根离子,亚硫酸氢根离子电离生成亚硫酸根离子和氢离子,H2SO3?H++HSO3-,HSO3-?H++SO32-,以上反应都是可逆反应,所以存在的含有硫元素的微粒有(除二氧化硫外)H2SO3、HSO3-、SO3 2-,
故答案为:H2SO3、HSO3-、SO3 2-;
(3)亚硫酸钠和亚硫酸氢钠都是强碱弱酸盐,都能发生水解,水解反应方程式为:亚硫酸钠的水解,SO32-+H2O=HSO3-+OH-、HSO3-+H2O=H2SO3+OH-;亚硫酸氢钠的水解,HSO3-+H2O=H2SO3+OH-;通过水解方程式看出,无论亚硫酸钠还是亚硫酸氢钠都能水解生成亚硫酸,故该说法错误,
故答案为:不正确,因亚硫酸根离子和亚硫酸氢根离子都会水解生成亚硫酸;
(4)①亚硫酸钠和亚硫酸氢钠都能电离和水解,但水解是微弱的,电离程度大于水解程度;亚硫酸氢根离子能电离出亚硫酸根离子,但较弱,所以亚硫酸氢钠溶液中的亚硫酸根离子比亚硫酸钠溶液中的小;亚硫酸氢钠溶液中的亚硫酸氢根离子比亚硫酸钠溶液中的大;亚硫酸根离子的水解程度大于亚硫酸氢根离子的水解程度,且亚硫酸根离子的第二步水解更弱,所以亚硫酸氢钠溶液中的亚硫酸比亚硫酸钠溶液中的大,
故答案为:小;大;大;
②根据实验和分析,得出的结论是使品红褪色的微粒是亚硫酸根离子,
故答案为:使品红褪色的微粒是亚硫酸根离子.

43. B。由第三段中的people to live in the moment及the minimum amount of connectedness可推断,Light Phone的设计宗旨是使它被使用得尽可能“少(little)”。
