Why is carbon valency four
Question- When preparing cyclopentylmagnesium bromide from bromocyclopentane and magnesium there is one unavoidable side reaction that often takes place and could reduce the yield of the reaction. Draw a reaction to illustrate this phenomenon
While reasonably dilute HCl and AgNO3 solutions are mixed a white AgCl precipitate forms with some heat evolving. While a Na2S2O3 solutions is added to this reaction mixture the white precipitate disappears upon stirring.
Tungsten has a BCC structure, an atomic radius of 0.137 nm and an atomic weight of 183.84 g/mol. Compute its theoretical density.
One way to recrystallize a solute from a solution is to change the temperature. Another way is to evaporate solvent from the solution. A 340 g sample of a saturated solution of KNO3 in water is prepared at 25.0.
