2. A flask and stopper with a volume of 25.4ml weighing 15.8156g is used to perform this experiment. The conditions are P=768mm and T=99.5' C. The recondensed
vapor and the stoppered flask have a mass of 15.8793g. What is the MW of the
compound? Show all work.

a chemical reaction happens

explanation:

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
