Are there any chemical bonds or forces of attraction between a solid surface (such as a glass (SiO2) or a polypropen (C3H6) plate) and a liquid drop of water/of oil? if yes, what kind?

Provide a stepwise curved arrow mechanism that fully explains the outcome of the reaction shown below. oh нао* heat он

How do you know when a chemical reaction has occurred

The solid xy decomposes into gaseous x and y: xy(s) m x(g) + y(g) kp = 4.1 (at 0 °c) if the reaction is carried out in a 22.4 l container, which initial amounts of x and y will result in the formation of solid xy?
