Acteria and archaea fix nitrogen (n2) by reducing it to ammonia (nh3), the form of nitrogen assimilated by plants. the main rese
jenyasd209 [6]

The correct answer for this question is the atmosphere.

The transformation of atmospheric N2 into NH3, which is a form that plants may use, is known as biological nitrogen fixation. However, eukaryotes do not engage in the process; it is exclusive to bacteria and archaea.

It has long been recognized that some archaea can contribute to the nitrogen cycling processes (albeit some of these organisms were not initially recognized as archaea). These included both assimilatory and dissimilatory activities, such as the fixing of atmospheric nitrogen. However, rather than large terrestrial or aquatic environments, these reactions were linked to extremophilic archaea that are generally found in 'exotic' habitats like hot springs or salt-saturated lakes.

Chemical reaction (dissociation) 1: C₂O₄H₂(aq) ⇄ C₂O₄H⁻(aq) + H⁺(aq).
Chemical reaction (dissociation) 2: C₂O₄H⁻(aq) ⇄ C₂O₄²⁻(aq) + H⁺(aq).
c(C₂O₄H⁻) = c(H⁺) = x.
c(C₂O₄H₂) = 0.0269 M.
pKa₁ = 1.23.
Ka₁ = 10∧(-1.23) = 0.059.
Ka₁ = c(C₂O₄H⁻) · c(H⁺) / c(C₂O₄H₂).
0.059 = x² / (0.0269 M - x).
Solve quadratic eqaution: x = c(H⁺) = 0.02 M.
pH = -log(0.02 M) = 1.7.
