题目

Are you looking for some new and exciting places to take your kids (孩子) to? Try some of these places： •Visit art museums. They offer a variety of activities to excite your kids' interest. Many offer workshops for making hand­made pieces, traveling exhibits, book signings by children's favorite writers, and even musical performances and other arts. •Head to a natural history museum. This is where kids can discover the past from dinosaur(恐龙) models to rock collections and pictures of stars in the sky. Also, ask what kind of workshops and educational programs are prepared f二氯化硫（SCl2）熔点-78°C，沸点59°C，密度1.638g/cm3，遇水易分解，以下是由氯气与硫反应合成二氯化硫的实验装置，其中F中装有无水CaCl2固体．试回答下列问题：（1）装置A中发生反应的化学方程式为：MnO2+4HCl（浓）  △  . MnCl2+Cl2↑+2H2OMnO2+4HCl（浓）  △  . MnCl2+Cl2↑+2H2O（2）装置C中盛放的试剂是浓硫酸浓硫酸，装置F的作用为防水从后面进入E使二氯化硫分解防水从后面进入E使二氯化硫分解（3）实验开始前先排尽系统中空气，此做法目的是防止加热硫粉时，空气中的氧气与硫粉反应防止加热硫粉时，空气中的氧气与硫粉反应再向D中放入一定量的硫粉，加热使之融化，然后摇动烧瓶使硫附着在烧瓶内壁形成一薄层膜，这样做的目的是增大接触面积以加快反应速率增大接触面积以加快反应速率（4）实验时，如何防止E中液体挥发将锥形瓶放入冰水中冷却将锥形瓶放入冰水中冷却（5）画出虚线框内与F连接的仪器，并指出其中盛装试剂名称，以完善该实验装置．
