Answer:
case1.
The addition of acid and base leads to a change in pH of the water when adding to deionized water due to fact that acid and bases dissociated in dissolving in water. If the H+ ion increases in the water as acid addition hikes it, it will result in decreasing the pH value. The intensity of the acid also affects the dissociation of the ions.
case2
Buffers are normally formed by weak acid and its conjugate base, and adding acid to the buffer it absorbs the H+ ions so the pH will be lower and adding base or increase of OH- conjugate base resists the pH value to increase.
CO2 ; H20- They are the only ones that, on both sides, combined with another element and bonding of atoms
Answer:
Random particle motion in liquids and gases is a difficult concept for in temperature, the particles move faster as they gain kinetic energy.
Explanation:
Because the oily part of its molecule tends to lay up against solid surfaces, but without much in the way of areas of electric charge that would cause it to stick more firmly to that surface.
The correct answer is the one in the middle. Mixing food coloring and water
