Albert Einstein was born in 1879. As a boy he was not happy in school. He seemed to be slower than others and he often failed in his exams. Most of his teachers did not like him. His parents, however, loved him very much. They often said to the teachers, “Albert is a bright boy. He failed in some of the exams because he had no interest in those subjects.” They believed their son would do something great. One day, the Einsteins and their friends were having a picnic by the riverside. Someone said, “See how the other children play and laugh, but not Albert. He just sits and looks off across the river.” Albert’s mother heard this and said, “Albert is quiet, because he’s thinking. Let’s wait and see. He’ll become a great scientist, I believe.”

She was right. Later, Albert became one of the greatest scientists in the world. He won the Nobel Prize for physics in 1921.

水钴矿中除SiO2外,还有9.24% CoO、2.78% Fe2O3、0.96% MgO、0.084 % CaO。从中提取钴的主要工艺流程如下:

(1)在一定浓度的H2SO4溶液中,钴的浸出率随时间、温度的变化如图所示。考虑生产成本和效率,最佳的浸出时间为       小时,最佳的浸出温度为     ℃。

(2)请配平下列除铁的化学方程式:

Fe2(SO4)3+   H2O+   Na2CO3=   Na2Fe6(SO4)4(OH)12↓+   Na2SO4+   CO2

(3)“除钙、镁”的原理反应为:MgSO4+2NaF=MgF2↓+Na2SO4 ;CaSO4+2NaF=CaF2↓+Na2SO4

已知Ksp(CaF2)=1.11×10-10,Ksp(MgF2)=7.40×10-11,加入过量NaF溶液反应完全后过滤,则滤液中       

(4)“沉淀”中含杂质离子主要有SO42、F         ;“操作X”包括             

(5)某锂离子电池正极是LiCoO2,含Li+导电固体为电解质。充电时,Li还原为Li,并以原子形式嵌入电池负极材料碳-6(C6)中(如图所示)。电池反应为LiCoO2+C6 CoO2+LiC6,写出该电池放电时的正极反应式
