A Lewis acid is a compound that accepts an electron pair (the H+ ion in our example). Molecular Meanings Lewis bases are chemicals that can donate electron pairs. Lewis acids are chemicals that can accept them. Though we had ammonia donating a lone pair to a proton in our example, the ...
Answer to: What role do the following chemicals play in digestion: Pepsin, Bile, Trypsin, Lipase, HCl, Histamine, Somatostatin, Gastrin, Amylase,...
What does phenolphthalein look like when it is mixed with an acid (HCl) and what does it look like when it is mixed with a base (NaOH)?What are these chemicals called? Write a complete (i.e. balanced equation with phases) for the ...
the salinity of ocean water horizontal and vertical distribution of salinity numerous chemicals such as chlorine, hydrochloric acid, carbon dioxide, and antiscalants are produced in the desalination process that can be harmful in high concentrations. know more on hazardous substances at the given link...
Generation-3a,9-propanol-3aH-cyclopentacycloocten-8-yl ester (5). In addition, after reacting D-valine with methyl acetoacetate, it is reacted with isobutyl chloroformate to form an acid anhydride, and then reacted with 5 to form an amide and then deprotected with hydrochloric acid to ...
Adding tiny amounts of chemicals like boron and phosphorous to purified silicon is calleddoping. Purified silicon is used to make extrinsic semiconductors — like those used in solar cells. However, the conductivity of intrinsic semiconductors is too low and sensitivity to temperature too high to pe...
Another method involves electrolysis of a cooled solution of zinc chloride in hydrochloric acid. This process can yield large quantities of pure crystals of zinc chloride. However, this manufacturing process also produces byproducts known as "waste." These waste byproducts, called polychlorinated dibenz...
Methanesulfonyl chloride has been used in many fields, such as raw materials in fine chemicals production, catalyst, analytical agent and so on. Specific uses are as following [3-6]: • Methanesulfonyl chloride reacts easily with compounds with active hydrogen, so it can be used to react wit...
The main uses of Benzenesulfonic acid have been introduced above. Interested consumers can privately explore more detailed information. When choosing chemicals, it is preferable to understand their efficacy and effects before use. Blind use can cause irritation and harm to one's health.Share...
Consuming many of these chemicals in combination over a lifetime may have a different effect. Some products include pigments from natural sources. Here are some that the FDA have approved: annatto extract: yellow dehydrated beets: bluish-red to brown caramel: yellow to tan beta-carotene: yellow...
