Ammonia is both a donor and an acceptor of hydrogen in hydrogen-bond formation. Draw a diagram showing the hydrogen bonding of an ammonia molecule with two other ammonia molecules. (Draw complete Lewis structures. Assign radical electrons, lone pairs, and atomic charges as appropriate. Use the "Any" or "Coordinate Covalent" bond type to indicate the hydrogen bond(s).)
Disulfur dichloride is produced by reacting chlorine gas with molten sulfur. What is the percent yield if 3.25 g S2Cl2 is isolated from the reaction of 5.0 g S8 and 3.75 g Cl2
