英语翻译
The resulting deep yellow oil was dissolved in 200 ml of pyridine and 100 ml of water was dropped in
slowly while stirring in an ice bath.a After stirring for 10 min at room temperature,hexane-ethyl acetate (1:l) and water were introduced.The organic layer was separated and after washing with base,acid,and water,it was dried over magnesium sulfate and concentrated to give 41.2 g of a yellow solid.At this point the only contaminants remaining were the keto acetate 3 and a small amount of starting olefin 1.Distillation afforded 27.9 g (48% yield) of dione 2,bp 83-85' (0.1 mm),mp 42.5-43.5';' the pot contained 12.3 g of essentially pure keto acetate 3.Using methanolic potassium hydroxide the keto acetate was hydrolyzed to the a-hydroxy ketone which in the same
reaction vessel,following the procedure of Blomquist and Goldstein,* was oxidized by cupric acetate to dione 2 in 90% yield (9.1 g) This raised the total isolated yield of a-diketone 2 to 37.0 g (63 %).
Reaction 2 was also performed on a large scale and 42.1 g(O.300 mol) of 1-decene (5) was transformed to 22.7 g (36% isolated yield) of keto acetate 6,mp 49-55°.9 With the following exceptions the procedure was identical with that described for oxidation of 1.108 g of anhydrous potassium acetatelo was added to the reaction mixture before permanganate addition ;
after permanganate addition,stirring was continued in the ice-salt bath for 5 hr.

1.2dm3 of hydrogen gas dissolved in 100cm3 of water.
how many mols of hydrogen chloride gas are present?
第一行不是hydrogen gas，是hydrogen chloride gas，另外，hcl并没有在水中消失。就像盐放在水里，这样的溶液还是有浓度的。

问一道数学题,涉及到微分方程
a tank contains 4 lbs of salt dissolved in 100 gallons of water.Suppose that brine containing 2 lbs of salt per gallon of water is allowed to enter the tank at a rate of 5 gallons/minute,and that the mixed solution is drained from the tank at the same rate.Use the differential equation to find the amount of salt after 10 minutes.
大致翻译下:
一个水缸有盐水,此盐水由4磅的盐溶解在100加仑水里.
假设把 [2磅盐/1加仑 的盐水] 往这个水缸里灌入,速度是5加仑/分钟,同样的,灌入的同时,此水缸以相同的速度往外漏水.
请问10分钟后这个水缸里还有多少盐?

英语翻译
A 2.50 gram of bronze was dissolved in sulfuric acid.The copper becomes copper (II) sulfate with sulfur dioxide and water the other products.The copper (II) sulfate is then mixed with iodide ion solution to form copper(I)iodide and the triiodide ion(I3-) and sulfate ions.The triiodide ion is next titrated with thiosulfate(S2O3^ 2-) to form iodide ions and S4O6^ 2- ions.Write and balance the equations and calculate the percent by mass of copper in the original sample if 21.5mL of 1.25 M thiosulfate is need in the titration.

不解句中“无法”怎样翻译出来,dissolved是溶于, solution是溶液吗?“之后”是根据dissolved时态译的?
The mineral elements from the soil that are usable by the plant must be dissolved in the soil solution before they can be taken into the root.
其翻译：土壤里的矿物质是无法被植物直接利用的,它们只有在溶于土壤中的溶液之后,才能为植物的根系所吸收.
taken into the root是根系所吸收的意思?
