I need more help on the other chart please
Calculating pH
see chart below

2, acidic, 5, acidic

Explanation:

pH = -log[H+], where [H+] is the concentration of H+.

Using the data in the table, you can calculate the pH:

-log[1e-2] = 2

-log[1e-5] = 5

To find out whether it is acidic, basic, or neutral, use a pH scale. Anything less than 7 is acidic, anything over is basic. Knowing this, both (except the middle, which you did correctly) are acidic.

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 natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
