Lithium, sodium, potassium, magnesium, calcium, barium, boron, aluminum, nitrogen, phosphorus, sulfur, fluorine and xenon are all examples of elements that react with oxygen. Oxygen reacts with other elements but those reactions are relatively mundane.

<span>THE HIGHEST CONCENTRATION OF HYDROGEN IONS IS LOCATED IN THE INTER-MEMBRANE SPACE. HYDROGEN IONS REACH THE INTER-MEMBRANE SPACE THROUGH PROTEIN CHANNELS EMBEDDED IN THE MITOCHONDRIAL MEMBRANE. THE MAIN FUNCTION OF INTER MEMBRANEIS OXIDATIVE PHOSPHORLATON. ENERGY IS REQUIRED TO MOVE THE HYDROGEN IONS ACROSS THE MEMBRANE BECAUSE THE HYDROGEN IONS ARE MOVING AGAINST THE CONCENTRATION GRADIENT. H+ GOES AGAINST THE CONCENTRATION GRADIENT THE USE OF THE GRADIENT TO DRIVE ATP SYNTHASE. HYDOGEN IONS DRIVE ATP SYNTHASE IN PHTOSYNTHESIS. THIS HAPPENS WHEN HYDROGEN IONS GET PUSHED ACROSS THE MEMBRANE CREATING A HIGH CONCENTRATION INSIDE THE THYLAKOID.</span>
Answer:
AgI, AgBr, AgCl and Ag₂CrO₄
Explanation:
Ksp (product solubility constant) is defined as the equilibrium constant of the general reaction:
XₐYₙ(s) → aXⁿ⁺(aq) + nYᵃ⁻(aq)
<em>Where X is cation and Y is anion.</em>
Ksp = [aXⁿ⁺]ᵃ [nYᵃ⁻]ⁿ
The presence of XₐYₙ(s) produce ax moles of aXⁿ⁺ and nx moles of Yᵃ⁻. <em>Where X is the solubility of the compound.</em>
Replacing in Ksp:
Ksp = [ax]ᵃ [nx]ⁿ
Solving for x, Solubility (S) is defined as:
![S = \sqrt[n+a]{\frac{Ksp}{a^{a} n^n} }](https://tex.z-dn.net/?f=S%20%3D%20%5Csqrt%5Bn%2Ba%5D%7B%5Cfrac%7BKsp%7D%7Ba%5E%7Ba%7D%20n%5En%7D%20%7D)
For AgCl, Ag₂CrO₄, AgBr and AgI solubilities are:
![S = \sqrt[2]{\frac{1.8x10^{-10}}{1} }](https://tex.z-dn.net/?f=S%20%3D%20%5Csqrt%5B2%5D%7B%5Cfrac%7B1.8x10%5E%7B-10%7D%7D%7B1%7D%20%7D)
= 1.34x10⁻⁵M
![S = \sqrt[3]{\frac{1.1x10^{-12}}{4} }](https://tex.z-dn.net/?f=S%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B1.1x10%5E%7B-12%7D%7D%7B4%7D%20%7D)
= 6.50x10⁻⁵M
![S = \sqrt[2]{\frac{5.4x10^{-13}}{1} }](https://tex.z-dn.net/?f=S%20%3D%20%5Csqrt%5B2%5D%7B%5Cfrac%7B5.4x10%5E%7B-13%7D%7D%7B1%7D%20%7D)
= 7.35x10⁻⁷M
![S = \sqrt[2]{\frac{8.5^{-17}}{1} }](https://tex.z-dn.net/?f=S%20%3D%20%5Csqrt%5B2%5D%7B%5Cfrac%7B8.5%5E%7B-17%7D%7D%7B1%7D%20%7D)
= 9.22x10⁻⁹M
The lower solubility is the first compound in precipitate, thus, order of precipitation is:
<em>AgI, AgBr, AgCl and Ag₂CrO₄</em>
