Answer:
pH is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than 7 are acidic, while those with a pH greater than 7 are basic or alkaline. A pH level of 7.0 at 25°C is defined as "neutral" because the concentration of H3O+ equals the concentration of OH− in pure water. On the other hand, electrical conductivity is a non-specific measurement of the concentration of both positively and negatively charged ions within a sample. So the short answer to the question is as follows, the presence of any hydrogen ions present in a substance will impact the pH level and most probably influence conductivity levels. However, hydrogen ions make up only a small part of the ion concentration measured by a conductivity meter.
Answer: remove toxins from the body
Explanation: think of it. When you are sick you throw up. When you eat too much food you throw up
The balanced nuclear equation for the reaction is
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
From the question given above, we were told that:
<u>A fast-moving neutron strikes a ²³⁵U nucleus. The nucleus shatters producing ¹⁵⁵Sm, ⁷⁸Zn, and three neutrons.</u>
The nuclear equation can be written as follow:
Neutron => ¹₀n
Uranium => ²³⁵₉₂U
Samarium => ¹⁵⁵₆₂Sm
Zinc => ⁷⁸₃₀Zn
Uranium + neutron —> Samarium + Zinc + 3 moles of neutron
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
The nuclear equation above is balanced.

Correct answer is 
.
Phosphoric acid is a polyprotic acid having 3 acidic hyrdogen therefore it will have 3 pka values.
The equations for the release of acidic hydrogen can be written as:
From the pka values we can judge the idea of pH as using Henderson-Hasselbalch Equation, we get the relation between pH and pka.
Using the following equation, relation of pH and pka is
![pH=pka+log\frac{[A^-]}{HA}](https://tex.z-dn.net/?f=pH%3Dpka%2Blog%5Cfrac%7B%5BA%5E-%5D%7D%7BHA%7D)
Using this equation, we can find that the equation having pka= 2. 14 is closest to the pH=3.2 so the ionic form in this equation will be dominant at the same pH.
Therefore at pH=3.2 the ionic form of 
is dominant.
22, because you just add the protons and neutrons (12 + 10)
