(14分解:在第三象限:粒子受电场力做匀加速直线运动在第二象限:粒子受洛伦兹力做匀速圆周运动在第一象限:粒子受电场力做类平抛运动粒子的运动轨迹如图所示分2)设粒子飞出极板的速度为v20q200m/s由动能定理2-0解得粒子在磁场中做匀速圆周运动,洛伦兹力提供向心力gvb-m解得轨迹半径分3)粒子从B点到C点做类平抛运动沿x轴方分沿y轴负方向分由牛顿第二定律得B=分解得400V/m分

11.B【试题解析】含有0.1molFel2的溶液与足量Cl2反应,Fe2-、I-均会被氧化,1甚至被氧化理科综合·化学试题答案第1页(共7页)成碘酸根,0.1molFel2反应转移的电子数远超0.2NA,含0.1molNa2SO3的溶液与足量氯气反应,转移电子数为0.2NA,A错误;2Al+2NaOH+2H2O=2NaAlc2+3H2↑,2Al+3H2SO4=Al2(SO4)3+3H2↑,1molAl反应均产生1.5molH2,即1.5NA个H2,B正确,选B;因为没有确定温度和压强,因此无法计算甲烷和乙烯的物质的量,也就无法计算气体中氢原子数,C错误;1mol2HCl、1mol3HCl含有的质子数相等,均为18mol,D错误。
