There are three preparation methods of methylsulfonyl chloride [1]. The first is made from thiourea by methylation and chlorine oxidation. The second is made by the reaction of methanesulfonic acid and sulfoxide. The third is made from methyl mercaptan obtained by wet chlorination. At present, in...

Metalloids are elements that have properties in between those of metals and nonmetals. The physical properties of metalloids are similar to those of metals, they are solid and lustrous, while the chemical properties are similar to those of nonmetals since they tend to gain electrons. ...
molecules often exist in the soil. nitrogen can be present in nitrates and nitrites in water and in soil. these compounds are all part of the nitrogen cycle and both are interconnected. nitrogen cycle a cycle is a sequence of events or steps that repeats itself regularly. in the nitrogen ...
