6.一包白色粉末,其中可能含有NaCl、Ba(NO32、CuSO4、Na2CO3,现做以下实验:

①将部分粉末加入水中,振荡,有白色沉淀生成,过滤,滤液呈无色

②向①中的沉淀物中加入足量稀硝酸,固体完全溶解,并有气泡产生

③取少量②的溶液,滴入稀硫酸,有白色沉淀产生

试根据上述实验现象判断,原白色粉末中

一定含有的物质是{#blank#}1{#/blank#},

一定不含的物质是{#blank#}2{#/blank#},

可能含有的物质是{#blank#}3{#/blank#}(以上物质均写化学式),

写出第①步中反应的化学方程式:{#blank#}4{#/blank#},

第②反应步中离子方程式:{#blank#}5{#/blank#}.

7.汽车发动机用水散热,这是因为水的比热容{#blank#}1{#/blank#}(填“大”或“小”).在相同条件下,吸收的热量较多.质量为1kg的水,温度从20℃升高到70℃,吸收的热量是{#blank#}2{#/blank#}J.[水的比热容为4.2×103J/(kg•℃)].
