Answer:
B
Explanation:
<h2>Soil is a mixture of </h2><h2 /><h2>tiny particles of rock,</h2>
<h2>dead plants and animals </h2>
<h2>,air and water.</h2>
Ca(OH)₂ ==> Ca²⁺ + 2 OH<span>-
Ca(OH)</span>₂ is <span>strong Bases</span><span>
</span>Therefore, the [OH-] equals 5 x 10⁻⁴ M. For every Ca(OH)₂ you produce 2 OH⁻<span>.
</span>
pOH = - log[ OH⁻]
pOH = - log [ <span>5 x 10⁻⁴ ]
pOH = 3.30
pH + pOH = 14
pH + 3.30 = 14
pH = 14 - 3.30
pH = 10.7
hope this helps!</span>
1) Assume M refers to a general element and Z referes to other general element.
2) Assume the chemical formula of the ionic compound is MₓZₐ
3) Then the dissociaton would be written:
MₓZₐ → XMᵃ⁺ + AZˣ⁻
That means that the ionic compoud will lead to the X cations Mᵃ⁺ whose oxidation state are a+, and A anions Zˣ⁻ whose oxidation state is x⁻.
5) For example: MgBr₂ (aq) → Mg⁺² (aq) + 2Br⁻ (aq)
6) Explanation: since the water molecules are polar, they will surround (solvate) the three ions that form the compound MgBr₂, overcoming the electrostatic forces that hold together the atoms in the ionic lattice.
The compound with the highest melting point is CH3 [CH2]14COOH.
This compound has the highest melting point because it has the highest number of CH2 bonds. The melting point of a compound refers to a particular temperature at which that substance changes from a solid to a liquid.
