B
Four-year-old Camila loves to dress up and rarely leaves the house without lipstick. Camila's mother Annette Vea Lopez didn't always know how to respond to Camila's self-expression, but since participating in the Casa de los Ninos Parents as Teachers program, she now accepts her daughter's fashion choices happily.
“Camila’ s been very independent since she was very young,” Vea Lopèz said. “Adults would always comment on her makeup and how she dressed. She was always very girly. She's 4now and still that way. That's just her personality. We love her just as she is. And we love thatParents as Teachers always encouraged us to let Camila be herself.”
Vea Lopez heard about the Parents as Teachers home visitation program from a friend who suggested that she take part with then 1-year-old Camila. The FTFPSRP Council funds this program to help parents become their child's first and best teachers. Parents as Teachers gives families personalized, in-home support through a trained parent educator.
During home visits, the parent educator introduced the family to activities that support social-emotional development, such as being able to recognize and label emotions. Vea Lopez notices the impact these activities have had on her daughter. “I see that Camila's confidence and self-esteem have grown. She began to open up to me more and talk about when she was feeling anxious or what she needed support with.” said Vea Lopez.

【点睛】本题重点Ⅱ，在原电池中，相对活泼的金属电极为负极，相对不活泼的金属电极或非金属电极作正极，且负极材料能与电解质溶液发生氧化还原反应；设计原电池时，需分析电池反应，失电子的反应物作负极，得电子的离子来自电解质。
18． Ag2SO4 有黑色固体（Ag ）生成，加入KSCN 溶液后变红 Fe2+－e-＝Fe3+ 负 Fe2+＋Ag+Fe3+＋Ag 不能 因为Fe(NO3)3溶液呈酸性，酸性条件下NO3-也可能氧化Ag 溶液中存在平衡：Fe3+＋AgFe2+＋Ag+，且AgCl比Ag2SO4溶解度更小，Cl-比SO42-更有利于降低Ag+浓度，所以实验Ⅴ比实验Ⅳ正向进行的程度更大（或促使平衡正向移动，银镜溶解）。
（1）将2mL 1mol/L AgNO3溶液加入到1mL 1mol/L FeSO4溶液中发生复分解反应会生成硫酸银白色沉淀，银离子具有强氧化性会氧化Fe2+为Fe3+，银离子被还原为黑色固体金属单质银；取上层清液，滴加KSCN溶液溶液变红说明有铁离子生成；
①上述分析可知白色沉淀为硫酸银，它的化学式是Ag2SO4，故答案为Ag2SO4；
②甲同学得出Ag+氧化了Fe2+的依据是实验现象中，银离子被还原为黑色固体金属单质银，取上层清液，滴加KSCN溶液溶液变红说明有铁离子生成，故答案为有黑色固体（Ag）生成，加入KSCN溶液后变红；
（2）①实验过程中电压表指针偏移，偏移的方向表明：电子由石墨经导线流向银，依据原电池原理可知银做原电池正极，石墨做原电池负极，负极是甲池溶液中亚铁离子失电子发生氧化反应生成铁离子，a中甲烧杯里的电极反应式是Fe2+-e-=Fe3+；故答案为Fe2+-e-=Fe3+；
②随后向甲烧杯中逐渐加入浓Fe2（SO4）3溶液，和乙池组成原电池，发现电压表指针的变化依次为，偏移减小→回到零点→逆向偏移，依据电子流向可知乙池中银做原电池负极，发生的反应为铁离子氧化为银生成亚铁离子；故答案为负；


答：该样品中碳酸钙的质量分数为。
