Bonus Question 13)
Ocean acidification is of considerable concern to environmental scientists as it could impact ocean biodiversity significantly. What
is the most likely chemical reaction that contributes to the change in ocean pH?
A)
Carbon dioxide interacts with ocean water to form carbonic acid, which
Lowers ocean pH.
B)
Nitrous oxide interacts with ocean water to form nitric acid, which
increases ocean pH.
Decaying organic matter in the ocean releases acetic acid, which lowers
the oceanic pH.
D)
Sulfur dioxide interacts with atmospheric water vapor to form sulfuric acid
which falls into the oceans, lowering the pH.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

. ph changes the ability of them he enzyme to dissolve in water.
