Which best describes how the atmosphere's CO2 content was regulated before the Industrial Revolution? Which best describes how the atmosphere's CO2 content was regulated before the Industrial Revolution? Inputs of CO2 to the atmosphere resulted from cellular respiration and widespread use of fossil fuels. These inputs were much greater than the uptake of CO2 by producers. CO2 was taken up by organisms for use in cellular respiration; a similar amount of CO2 was released by plants and other producers. CO2 was released by organisms as a by-product of cellular respiration; photosynthesis contributed additional CO2 to the atmosphere. CO2 was released by organisms as a by-product of cellular respiration; a similar amount of CO2 was absorbed by plants and other producers.

the ratio of the conjugate base to the acid required to attain the desired ph.

idk what is it? is this a question that you know the answer or u dont

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

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

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

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
