A metal, M, of atomic mass 56 amu reacts with chlorine to form a salt that can be represented as MCI, A boiling point elevation experiment is performed to determine the subscript I, and therefore, the formula of the salt. A 23.8 g sample of the salt is dissolved in 100.0 g of water and the boiling point of the solution is found to be 376 K. Find the formula of the salt. Assume complete dissociation of the salt in...

Zinc forms the cation, Zn2+. A mystery anion X is represented as X2. Given this information, what is the molecular formula of the salt it forms with zinc? (Chemical formula use subscript numbers, but for this question any required numbers may be formatted normally. Also, do not insert any spaces between the elements.) Answer: Library Home Students According to the VSEPR electron pairs in the valence energy level repel each other and are therefore arranged as far apart as possible....

EXPERIMENT7 PREPARATION OF PHARMACEUTICALS Fischer Esterification Reactions Almost 2500 years ago, physicians such as Hippocrates recommended that patients chew on the bark of the willow to alleviate pain. The active ingredient in willow bark was found to be salicin, a compound made of a molecule of salicyl alcohol bonded to a p-D-glucose molecule. In the stomach, the bond between...
