Learning goal: to understand the relation between the strength of an acid or a base and its pka and pkb values. the degree to which a weak acid dissociates in solution is given by its acid-ionization constant, ka. for the generic weak acid, ha, ha(aq)⇌a−(aq)+h+(aq) and the acid-ionization constant is given by ka=[a−][h+][ha] similarly, the degree to which a weak base reacts with h2o in solution is given by its base-ionization constant, kb. for the generic weak base, b, b(aq)+h2o(l)⇌bh+(aq)+oh−(aq) and the base-ionization constant is given by kb=[bh+][oh−][b]

Asa choose the correct set of reaction coefficients to properly balance the following chemical equation according to the law of conservation of mass: __s8 + __o2 ==> __so2 1, 1, 8 1, 8, 1 1, 8, 8 8, 1, 1

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Once similarity and one difference between a mixture of elements and a mixture of compounds
