Probably, anhydrous sodium carbonate, commonly known as soda ash and soda. It is an important raw material for glass, papermaking, soap, detergent, textile, tanning and other industries, and is also commonly used as a softener for hard water, and also used to make sodium compounds. Its industrial production methods mainly include ammonia-alkali method and combined alkali production method.

Summary. Hello dear, happy to answer for you! The chemical equation of each step of the reaction of Sowell alkali method and its chemical reaction principle is:
NaCl NH3 H2O CO2 NAHC3 NH4Cl2NAHC3 NA2CO3 H2O CO2 Cao H2O CA(OH)2,2NH4Cl Ca(OH)2 CaCl2 2NH3 2H2OA consists of three steps: NH3+CO2+H2O===NH4HCO3
Hello, hello very high buried and booked for the bend macro you answered! The chemical equation of each step of the reaction of Sowell alkali method is as follows: NaCl NH3 H2O CO2 NaHCO3 NH4Cl2NaHCO3 NA2CO3 H2O CO2 Cao H2O CA(OH)2, 2NH4Cl CA(OH)2 CACl2 2NH3 2H2O, a total of three steps:
nh3+co2+h2o===nh4hco3
Hello dear, happy to answer for you! Chemistry is a basic natural science that studies the composition, structure, quality, transformation and application of matter at the atomic and molecular levels. It originates from the practice of life and production, and continues to develop with the progress of human society.
Different from particle physics and nuclear physics, which study the smaller scale, the material structure of atoms, molecules, ions (groups), chemical bonds, intermolecular forces and other interactions are studied in chemistry, and the scale in which they are located is close to the macrocosm in the microscopic world, so their natural laws are also closely related to the physical and chemical qualities of substances and materials in the macrocosm of human existence. As an important bridge between the microcosm and macrocosm of the material world, chemistry is one of the main methods and means for human beings to understand and transform the material world.

In the late 19th century, Europe had already begun to transform the Sulvay Method. Germany has already achieved some success in this regard. In 1924, Germany had already developed the Cha'an method of alkali production.
This new method uses ammonium bicarbonate and salt as raw materials to obtain soda ash and ammonium chloride products, and the utilization rate of salt is 90%.
Alves was caught.
I believe fans are no strangers to Alves, he has played in Sevilla and Barcelona for a long time, has won many championships with Barcelona, and is also the main defender of the Brazilian national team for a long time, and later as he grows older, Alves chose to return to the Sao Paulo Club in the Brazilian league after a short period of time at Juventus and Grand Paris for 3 seasons, and retired there. >>>More

To cooperate I give you the method, captain I use 1 to represent, in order, 2 is the second player, 3 is the third player, and so on, now let's start talking about the method. >>>More
If you are willing to bother, leave the Mimi number, the more people the better, my number is still okay, there are a few full level, you can fight, right? Tactics talk about it for a while, and then assist me to fight, as long as I can fight, I have not been able to find anyone to fight with me. After 50 points, I don't have many points, so let's help! >>>More
