It was then  5 that the fairies had come and stolen the baby away and  6 the human baby with a fairy Changeling（2013?黄石）（1）用化学符号表示：①3个硫原子3S3S；②氧原子的结构示意图；③2个碳酸根离子2CO32-2CO32-．（2）如图所示是X、Y、Z三种不含结晶水的固体物质的溶解度曲线①物质Z的溶解度随温度的升高而BB．A．升高；B．降低；C．不改变②在高于t1℃高于t1℃的温度范围里，物质X的溶解度大于物质Z的溶解度．③将X、Y、Z三种物质的饱和溶液，由t1℃升温到t2℃（溶剂量不变），溶液中溶质的质量分数不变的是X、YX、Y（选填“X”、“Y”、“Z”）．
