Large carbohydrate molecules are built up in the reactions called condensations, in which monomeric carbohydrates are linked together in the larger units, while water is formed as other product.
On the other hand, large carbohydrate molecules are broken down in the reaction called hydrolysis, in which large units are separated into smaller one by addition of water.
Ans: pH = 9
<u>Given:</u>
Concentration of H+ ions [H+] = 1.0*10⁻⁹ M
<u>To determine:</u>
The pH of the above solution
<u>Explanation:</u>
pH = -log[H+]
pH = -log(1.0*10⁻⁹) = 9
Out of the choices given, the correct answer would be chlorine. It is the atom with the strongest attraction for electrons in a bond formation. This is because it has the highest electronegativity among the choices.
