The question is a picture pls help

The unknown alcohol = 2-propanol

Given

volume = 50 ml

mass = 39.4 g

Required

The unknown alcohol

Solution

Density of sample :

= mass : volume

= 39.4 g : 50 ml

= 0.788 g/ml

The unknown alcohol at room temperature = liquid, so the unknown alcohol is 2-propanol because it has temperature range between -90 to 82 for liquid and the density = 0.788 g/ml

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 .

i belive it is water
