From the time each of my children started school, I packed their lunches. And in each lunch, I  11  a note. Often written on a napkin (餐巾), it might be a thank-you for a  12  moment, a reminder of something we were happily expecting, or a bit of     13  for the coming test or sporting event.
In early grade school they  14  their notes. But as children grow older they becomes self-conscious(有自我意识的), and 15  he reached high school, my older son, Marc, informed me he no longer  16  my daily notes. Telling him that he no longer needed to  17  them but I still needed to write them, I  18  until the day he graduated.
Six years after high school graduation, Marc called and asked if he could move  19  for a couple of months. He had spent those years well, graduating from college,   20  two internship (实习) in Washington, D.C., and   21  , becoming a technical assistant in Sacramento,  22  short vacation visits, however, he had lived away from home. With his younger sister leaving for college, I was   23   happy to have Marc back. Since I was  24  making lunch for his younger brother, I    25  one for Marc, too.

Many children use the Internet to get useful knowledge and information, and to relax in their free time. But some of them are not using it in a good way. Here are some rules to make sure you are safe and have fun on the Internet.

Make rules for Internet use with your parents. For example, when you can go online, for how long and what activities you can do online.

Don’t give your password to anyone else, and never give out the following information: your real name ,home address, age, school, phone number or other personal information.

Check with your parents before giving out a credit card number.

Never send a photo of yourself to someone in e-mail unless your parents say it’s OK.

Check with your parents before going into a chat room. Different chat rooms have different rules and attract different kinds of people. You and your parents will want to make sure it’s a right place for you.

Never agree to meet someone you met on the Internet without your parent’s permission. Never meet anyone you met online alone.

Always remember that people online may not be who they say they are. Treat everyone online as if they were strangers.

If something you see or read online makes you uncomfortable, leave the site. Tell a parent or a teacher right away.

Treat other people as you’d like to be treated. Never use bad language.

(14分).以富含硫酸亚铁的工业废液为原料生产氧化铁的工艺如下(部分操作和条件略):

Ⅰ.从废液中提纯并结晶出FeSO4·7H2O。

Ⅱ.将FeSO4·7H2O配制成溶液。

Ⅲ.FeSO4溶液与稍过量的NH4HCO3溶液混合,得到含FeCO3的浊液。

Ⅳ.将浊液过滤,用90 ℃热水洗涤沉淀,干燥后得到FeCO3固体。

Ⅴ.煅烧FeCO3,得到Fe2O3固体。

已知:NH4HCO3在热水中分解。

(1)Ⅰ中,加足量的铁屑除去废液中的Fe3,该反应的离子方程式是_________________。

(2)Ⅱ中,需加一定量酸,该酸最好是    。运用化学平衡原理简述该酸的作用________________________________________________________________________。

(3)Ⅲ中,生成FeCO3的离子方程式是___________________________________________

若FeCO3浊液长时间暴露在空气中,会有部分固体表面变为红褐色,该变化的化学方程式是_______________________________________。

(4)Ⅳ中,通过检验SO来判断沉淀是否洗涤干净,检验SO的操作是__________

________________________________________________________________________。

(5)已知煅烧FeCO3的化学方程式是4FeCO3+O22Fe2O3+4CO2。现煅烧464.0 kg的FeCO3,得到316.8 kg产品。若产品中杂质只有FeO,则该产品中Fe2O3的质量是________kg。(摩尔质量/g·mol1:FeCO3 116 Fe2O3 160 FeO 72)
