in the 1H NMR spectrum for ethanol, we expect to have peaks (enter number of peaks), with an integration ratio of (enter integration ratio).The farthest downfield peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group). The most shielded peak is for the hydrogen(s) attached to the (enter atom the Hydrogen is attached) in the group (enter chemical formula for the group).

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 .

the pseudoscience are like beliefs, theories, or like practices that are considered scientific
