Answer:
The answer is the explanation.
Explanation:
The acetic acid, CH3COOH, reacts with calcium hydroxide, Ca(OH)2, producing acetate ion, CH3COO- and water as follows:
2CH3COOH + Ca(OH)2 → 2CH3COO- + 2H2O + Ca²⁺
That means the moles of acetic acid decrease whereas the moles of acetate ion are increased. The ratio of [CH3COOH] / [CH3COO-] is different.
As a base is added, the concentration of H3O+ decreases increasing the pH.
That means:
<em>TRUE </em> A. The number of moles of CH3COOH will decrease.
<em>FALSE</em> B. The number of moles of CH3COO- will decrease.
<em>TRUE </em>C. The equilibrium concentration of H3O will decrease.
<em>FALSE </em>D. The pH will decrease.
<em>FALSE</em> E. The ratio of [CH3COOH] / [CH3COO-] will remain the same.
Answer:
newtons law states that every body in the universe attracts every other body with a force which is directly proportional to the product of their masses and inversely proportional to square of the distance between their centers
Let’s say you are a race car driver and you are trying to beat the other racers and then you decide to increase your speed and as you are increasing speed you are also increasing kinetic energy. Hope this helps :)
When a substance undergoes a physical change no new substance is formed.
