Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
2. Using o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials Kokai et al. (JP 05194484) used o-chlorobenzaldehyde and alkali metal salts of thioglycolic acid as raw materials to first condense and form the intermediate 2-formylphenylthioacetate. The intermediate undergoes...
What is an energy level? Explain the difference between a ground state and an excited state. Describe the change (if any) in potential energy and in kinetic energy among the molecules when gaseous PCl_3 condenses to a liquid at a fixed temperature. ...
The metal hydroxides condense (peptize) in solution to form an hybrid organic/inorganic polymer. Depending on reaction conditions, the metal polymers may condense to colloidal particles or they may grow to form a network gel. The ratio of organics to inorganics in the polymer matrix is ...

A vapor barrier is installed, then drywall. This situation is really bad, water vapor from the concrete escapes into the stud cavity and condenses on the back of the vapor barrier behind the drywall. Again, water creates a nasty mold situation in the stud bay....
