读后续写 One possible version)A bad guy just p/cked Kim up and took her away! yelled Julie. So shocked were Kims parents thatthey jumped up from the sofa and rushed over to Julie. Learning what had happened, they phoned thepolice without delay. The nextnt, they jumped into their car and drove off directed by Julie. By thenT had reached the alley, but the man was nowhere to be seen. "I must find Kim, "TJ said to himself. Heran along the alley to the end, where he spotted the man walking towards a white house. "Stop! Stop Withhese words, he charged at the guy fearlessly and held fast to Kim. However hard the guy tried to get rid ofTJ. TJ wouldnt give inAt that very moment, Kim s parents arrived. Help! Help! "TJ shouted. Immediately Kim's father tookoff toward the guy. Seeing this. he guy hurriedly let go of Kim and broke into a run. Kim's father dashedup, caught hold of him and pressed him to the ground. Kim ran crying into her mother s arms. Minutes later,the police arrived and arrested the guy. TJ breathed a sigh of relief and smiled happily. T]'s quick thinkingand bravery saved a little girl in the neighborhood from unimaginable consequences

10.A【解析】由于温度不变,K不变,在恒压条件下充入0.02 mol co:后,平衡逆向移动,再次达到平衡时c(CO2)=0.0125mol·L1,为等效平衡,A正确;由于温度不变,K不变,故恒压下充入0.02 mol Ar后,体系体积增大,c(CO3)下降,平衡正向移动,假设CaCO完全反应,由碳元素守恒可得n(CO2)=0.1mol.因是恒压恒温过程,由理想气体状态方程可得体积比等于气体的物质的量之比,即V1=1L,n1=0.0125mol,n2=0.02mol+0.1mol=0.12mol,解得V2=9.6L,此时0.1 molc(CO)=961≈00lml·L<00125ml,L,由此可知直至CaCO3反应完都不能达到平衡,此时c(CO2)<0.0125mol·L-1,B错误;由上述分析可知,容器甲达到平衡时,n(CO2)II g14g·mo0.025mol,由可逆反应CaCOj(s)=CaO(s)+Co(g)起始/mol0.10变化/mol0.0250.0250.025平衡/mol0.0750.0250.025可知,容器甲中剩余CaCO3的物质的量为0.075mol容器乙是恒压下达到平衡,体积V=1L温度不变.K值不变,可知容器乙达到平衡时c(CO2)=0.0125mol·L-1,n(CO2)=0.0125mol·L1×1L=0.0125mol由可逆反应CaCO3(s)=CaO(s)+CO,(g)起始/mol0.1变化/mol0.01250.01250.0125平衡/mol0.08750.01250.0125可知,容器乙中剩余CCO2的物质的量为0.0875mol则达到平衡后,容器乙中剩余固体的质量大于容器甲中剩余固体的质量,C错误;由上述分析可知.甲、乙两容器的情况下达到平衡时,由于温度相同,平衡常数相同,所以Kq=K乙=c(CO2)=0.0125,故D错误。故选A
