The ionization equation is:
HF ⇄ H(+) + F(-)
The ionization constant is Ka = [H(+)] * [H(-)] / [HF]
=> [H(+)] * [F(-)] = Ka * [HF]
Given that Ka < 1
[H(+)] * [F(-)] < [HF]
Which is [HF] > [H(+)] * [F(-)] the option a. fo the list of choices.
Answer:
The sinking of large masses of cool water gives rise to the (aka thermohaline circulation), which is derived by <u>density</u> gradients due to variations in the temperature and the <u>salinity</u>. The earth's rotation on its axis also influences deep ocean currents (the high and low tides).
Explanation:
Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water- Dictionary term
Density is the degree of compactness of a substance.- Dictionary term

Movement Across a Membrane and Energy. There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
The second element always ends in the -ide because it is named with the root+ide when they bond together.
