Dear Seth,

You’re only three years old, and at this point in your life you can’t read, much less understand what I’m going to try to tell you in this letter. But someday, when you’re ready, I hope you will find some wisdom and value in what I share with you.

Life can be cruel

小题1:  They’ll tease you or try to hurt you because you’re different.

There’s not much you can do except learn to deal with them, and learn to choose friends who are kind to you and who make you feel good about yourself. When you find friends like this, treasure them, spend time with them and love them.

Be open to life anyway

Yes, you’ll find cruelty and suffering in your journey through life, but don’t let that close you to new things. Don’t retreat from life, don’t hide or wall yourself off. 小题2: 

Life isn’t a competition

You will meet many people who will try to do better than you, in school , in college, at work. To them, life is a competition.

But here’s the secret: life isn’t a competition.  小题3:  Learn to enjoy the journey and make it a journey of happiness, of constant learning, of continual improvement, of love.

小题4: 

If there’s a single word you should live your life by, it should be this: love. It might sound corny, I know, but trust me, there’s no better rule in life.

Love not only your loved ones, but your neighbors, your co-workers, strangers, your brothers and sisters in humanity. And most of all, love yourself and learn to love yourself for who you are.

小题5: You are starting out on an unknown, tiring, scary, but ultimately incredibly wonderful journey, and always remember I will be there for you when I can.

Love,

Your Dad

实验题

碘酸钾(KIO3)主要用作食盐加碘剂

Ⅰ、制备碘酸钾实验室制备碘酸钾的路线如下:干海带→I2HIO3KIO3

(1)KIO3中I的化合价为            ,含碘盐中的碘是指      (填字母).

                        a、离子    b、元素    c、分子

(2)实验中需要用试纸测定溶液的pH,其操作方法是               

(3)过滤操作需要的玻璃仪器有玻璃棒、烧杯和        

(4)用冰水洗涤过滤所得KIO3晶体,其原因是              

(5)温度过高,会造成H2O2利用率降低,可能的原因是           

Ⅱ测定碘含量资料:

①碘酸钾与碘化钾反应方程式为:KIO3+5KI+3H2SO4=3K2SO4+3H2O+3I2

②淀粉溶液遇碘显色时,碘浓度越大颜色越深;

③扬州作为轻度缺碘地区,食盐中碘含量(以I计)应为18~33mg/Kg步骤1:配置以下各种试剂:100g/L食盐溶液,2.14×10﹣3 g/L KIO3溶液,测试液(含10g/L淀粉、196g/L H2SO4、1.66g/L KI).

步骤2:取5支相同规格小试管,贴上编号标签,按上表要求分别依次加入步骤1中配置的KIO3溶液,测试液、蒸馏水,塞上橡皮塞,混合后有序放置在试管架上(各试管中KIO3完全反应).

步骤3:另取一支小试管,一次加入步骤1中所配置的食盐溶液10滴、测试液10滴、和蒸馏水20滴,混合后与步骤2中各试管内颜色对照.

(6)步骤3所得溶液呈       色,则说明该食盐是含碘盐.

(7)步骤2实验的目的是                    ,步骤2中测试液的滴数保持一致的原因是                                       

(8)若步骤3所得溶液颜色与3号试管一致,则100mL该食盐溶液中含有碘酸钾              mg.该食盐中碘含量为          mg/Kg,           (填“符合”或“不符合”)扬州地区要求
