5.

在“质量守恒定律”的课堂教学中,老师引导同学们进行“化学反应中,反应物与生成物的质量关系”的实验探究.如图实验装置和选用药品,现分别以A、B、C、D表示如图所示:

A、B、C三个实验分别由甲、乙、丙三个组的同学来完成,D实验由丁组同学对镁条燃烧前后分别进行称量,他们都进行了规范的操作、准确的称量和细致的观察.

(1)A实验:白磷刚引燃,立即将锥形瓶放到天平上称量,天平不平衡.结论是:质量不守恒.待锥形瓶冷却后,重新放到托盘天平上称量,天平平衡.结论是:质量守恒.你认为结论正确的是{#blank#}1{#/blank#} (填“前一种”或“后一种”),而导致另一种结论错误的原因是{#blank#}2{#/blank#} .整个过程中小气球的变化是:{#blank#}3{#/blank#} 

(2)丙组同学认为C实验说明了质量守恒.请你从原子的角度说明为什么?{#blank#}4{#/blank#} ;乙、丁两组同学得到的错误结论是“实验B、D均说明质量不守恒”.老师指导同学们分析了B、D两个实验反应前后天平不平衡的原因.你认为B实验天平不平衡的原因是{#blank#}5{#/blank#} ;D镁条燃烧前后,质量不相等的原因是{#blank#}6{#/blank#} 

6.
