When a nonpolar liquid displays a convex meniscus, which of the following explains this behavior? a. it has a low surface tension, and therefore clings to the glass. b. the cohesive forces are stronger than the adhesive forces to the glass. c. the adhesive forces to the glass are stronger than the cohesive forces. d. the liquid's viscosity is low. e. none of these.

The correct answer is B.

Explanation:

The formation of meniscus occurs between liquids and a proper container. Water-based fluids like sap, honey, and milk have a concave meniscus in glass or other wettable containers. In a non-polar liquid, the cohesive forces are stronger than the adhesive forces, i.e. the particles of the liquid have a greater attraction to each other than to the material of the container.

A classic example of this is the convex meniscus formed by mercury in glass.

The cohesive forces are stronger than the adhesive forces to the glass

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
