                                                      How to Make a Budget (预算)
     Most likely, you aren't the family breadwinner. But doing a small job or getting a weekly allowance (零花钱)
would put some money in your pocket. For kids and grown-ups alike, money is easy to spend. If you aren't
careful, it can be gone in no time. Being responsible with your money is an important skill to learn-and the
sooner you start the better. Whether you are tracking your spending or saving for something special, creating
a budget can help you deal with your expenses and plan for the future. All you need are paper and a pencil-and
some self-control. First, take a look at our sample monthly budget. Then, use a separate sheet of paper to plan
your own. In the first two columns (栏), list your sources (来源) of income and how much you expect to earn
form them. In the third and fourth columns, list what you expect to spend your money on and the amount.
    The left-hand total should
be more than or equal to the
right-hand total. If it is, you
have an effective budget.
     Budgets are not complex,
but sticking to them can be
tough. When planning your
budget, be realistic about
your expenses. If you know

that you drop $ 18 at a movie, don't write $ 12 in that space simply because you wish you were spending less.
     If you are eyeing a big purchase, such as a $ 150 skateboard, spend less and save more until you have the
total amount. No matter how attractive it may be, avoid spending your savings. One day, you will thank yourself?

(13分)无水氯化镁是制备某种催化剂的中间体。某研究性学习小组设计实验方案进行制取无水氯化镁等实验。请填写下列空白。

[实验一]利用下图实验装置(夹持和加热装置省略),在HCl气流中小心加热MgCl2·6H2O晶体制取无水氯化镁(无水氯化镁易吸水)。烧瓶中发生的反应为:

NaCl+H2SO4(浓)===NaHSO4+HCl↑

(1)试剂X是         。第二个洗气瓶中的浓硫酸的作用是               

(2)该实验装置存在一个缺陷是                                         

[实验二]通过下列步骤,测定实验一所得产物中氯元素含量以确定产物是否含有结晶水:

①称取m1g样品置于烧杯中,充分溶解;

②加入足量硝酸银溶液,充分反应后,过滤;

③洗涤沉淀,干燥至恒重,称得沉淀质量为m2g。

(3)若步骤③的操作中未洗涤沉淀,将导致测得的氯元素含量       (填“偏高”或“偏低”)

(4)若测得m1=10.40,m2=28.70,则所得产品MgCl2·nH2O中n的值为      

[实验三]一定条件下,氯化镁与四氯化钛的混合物可作烯烃聚合反应的催化剂。为了探究温度、氯化镁固体的含水量以及粉碎方式对该催化剂催化效果的影响,设计如下对比实验:

实验序号氯化镁固体中氯元素含量/%温度/℃粉碎方式催化效果/g·g-1
170.9720滚动球磨3.9×104
274.4520滚动球磨5.0×104
374.4520振动球磨5.9×104
4ω100振动球磨 
       注:催化效果用单位时间内每克催化剂得到产品的质量来表示

(5)表中ω=               

(6)从实验1、2可以得出的结论是                              

(7)设计实验2、3的目的是
