Typically, an acid and a base react to form a salt and water.

典型地，酸和碱反应生成盐和水。

Hence, for the whole process, the reaction consumed equivalent of halogen acid and alcohol to produce halide and water.

反应实际消耗的是等当量的氢卤酸和醇生成卤代烃和水，是制备伯卤代烃非常有效和清洁的方法。

It generated through the water, not only can directly drink, but is a measurable, to ensure that health and safety of health-weak alkaline water.

In the samples containing aluminum sulphate, some ettringite crystalparticles are formed, which do not match with dihydrate gypsum crystals and increase thedefects in the hardened plaster. The strength decreases sharply with increase of aluminumsulphate amount.

硫酸铝的引入，使石膏浆体中生成部分钙矾石晶体，钙矾石晶体与二水石膏晶体不匹配，从而增加了硬化体内部的缺陷，因此，随着硫酸铝掺入量的增加，硬化体强度的降低比较严重。

In general as long as the temperature reaches 90 ℃, the common E. coli, hepatitis B virus and other bacteria have already perished, but we still continue to boil water, this area is to allow water in the calcium carbonate, magnesium carbonate and other ingredients to fully precipitate impurities, and the other On the one hand, because I am using tap water is treated with chlorine, so a certain degree of residual chlorine in water, in the process of boiling water, chlorine and impurities in the water will generate harmful substances called chloroform.

在一般的长期的温度达90℃，普通大肠杆菌，乙型肝炎病毒和其他细菌已经死亡，但我们仍烧开水，这方面是允许的碳酸钙，碳酸镁和其他水成分，杂质充分沉淀，以及对其他一方面，因为我使用的自来水是用氯处理，因此在水中的余氯，在一定程度上开水，氯和水中杂质的过程中，将生成所谓有害物质氯仿。

Methods IO(superscript - subscript 3) was prepared by quantitative oxidation of bromine water, with the excessive bromine removed with formic acid. In the presence of excessive iodide, I(superscript -) would be oxidized by I(superscript - subscript 3) to form 3 times of I(superscript - subscript 3) in mol, displaying maximal absorption at 286nm in ultraviolet zone and a slightly low apex at 345nm.ε286=1.3×10^5 Lmol^(-1)cm^(-1),ε345=8.1×10^4 Lmol^(-1)cm^(-1), with both showing high sensitivity.

利用溴水定量氧化I生成IO(上标-下标 3)，再用甲酸除去过量的溴，IO(上标-下标 3)在过量碘化物存在下氧化I产生3倍摩尔量的I(上标-下标 3)，在紫外光区的286nm具有最大吸收，并在345nm处另有一略低的吸收峰，ε286=1.3×10^5 Lmol^(-1)cm^(-1)，ε345=8.1×10^4 Lmol^(-1)cm^(-1)，均具有很高的灵敏度。

Low levels of the crust, melting point 3180 ℃, boiling point 5627 ℃, the relative density of 2053, the external F electronic structure 5d56s2, reaction time will be lost 1-7 electronic, but also can capture an electron, so oxidation number of 0,± 1, 2 , 3, 4, 5, 6 and 7, rhenium with the halogen in the fluorine, chlorine, bromine reaction halides dissolved in water, can dissolve in nitric acid and ammonia hydrogen peroxide solution, but do not dissolve in hydrochloric acid.

地壳中含量很低，熔点3180℃，沸点5627℃，相对密度2053，外围F 电子结构5d56s2，反应时会丢失1—7个电子，也可捕获一个电子，所以氧化数为0、±1、＋2、＋3、＋4、＋5、＋6和＋7，铼能与卤素中的氟、氯、溴反应生成溶于水的卤化物，能溶于硝酸和含氨过氧化氢等溶液，但不溶于盐酸。

The result shows that geopolymeric reaction is occurred when metakaolinte is activated by the compound solution of sodium silicate and sodium hydroxide, and the amorphous geopolymeric cement with layer structure and combination water is then formed.

结果表明：在氢氧化钠溶液和水玻璃的混合溶液的激发下偏高岭石发生了土壤聚合反应，生成了无定形的土聚水泥；该土聚水泥呈层状结构并含有非结合水

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
