Answer;Fish respiring and releasing carbon dioxide into the water.Mixing occurring at the surface of the ocean with the atmosphere.Explanation;Ocean absorb carbon dioxide in a number of ways. Fish and other animals in the ocean take in oxygen and give off carbon dioxide into the water. Ocean plants respires using oxygen and release carbon dioxide into the water.Oceans also absorbs carbon dioxide from the atmosphere when the air meets water. Wind causes waves and turbulence, giving more opportunity for eater to absorb the carbon dioxide.

Answer from: eweqwoewoji

Options (1) and (3)

Explanation:

Carbon dioxide is an important greenhouse gas present in the atmosphere. A small increase in the concentration of CO₂ can lead to an extensive increase in the earth's surface temperature.

This CO₂ gets mixed up with the ocean and eventually gets absorbed. The marine organism such as fishes, sharks, and sardines undergoes the process of respiration where they utilize the dissolved oxygen and in return gives out the CO₂ into the ocean. In addition to this, the atmosphere is comprised of various gases and above the ocean surface layers, there also is the presence of CO₂ that interacts with the ocean surface waves as the wind blows over the area. Also, due to the higher turbulence of these waves, the CO₂ gets mixes up readily with the ocean water, as a result of which the atmospheric CO₂ is transferred to the ocean.

This is how CO₂ is absorbed by the oceans.

Hence, the correct answers are options (1) and (3).

Answer from: Quest

the dissociation of nickel hydroxide is follows:

$ni(oh)_2 > ni^2^+ + 2 oh^-$

$ksp for no(oh)2 = 5.5 * 10^-^1^6$

$5.5 * 10^-^1^6 = s * (2 s)^2 = 4 s^3$

$s^3 = 137.5 * 10^-^1^8$

$s = 5.14 * 10^-^6 = [oh^-]$

the concentration of hydroxide ion is

$5.14 * 10^-^6 = [oh^-]$

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

$k = [ ni^2^+] * [oh^-]^2$

$6.1 * 10^-^1^6 = [ ni^2] * [5.14 * 10^-^6]^2$

$[ ni^2^+] = 0.23 * 10^-^4 mol /l$

thus, concentration of ni is 0.23 * 10^-^4 mol /l
