The concentration of hydrogen ion of a sample of vinegar : 1.514 x 10⁻⁷
<h3>Further explanation
</h3>
pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH = - log [H⁺]
pH of a sample vinegar = 6.82
The concentration of hydrogen ion :
![\tt 6.82=-log[H^+]\\\\(H^+]=10^{-6.82}=1.514\times 10^{-7}](https://tex.z-dn.net/?f=%5Ctt%206.82%3D-log%5BH%5E%2B%5D%5C%5C%5C%5C%28H%5E%2B%5D%3D10%5E%7B-6.82%7D%3D1.514%5Ctimes%2010%5E%7B-7%7D)
Answers are:
1) It can be separated by physical methods.
2) It can appear different from different sources.
3) It cannot be described by a chemical symbol or formula.
Mixture is composed of at least two substances.
Pure substance is made of only one type of atom (element) or only one type of molecule (compound), mixtures and solutions are made from two or more types of pure substances.
Mixtures can be separeted y physical means, while compounds cannot.
There is a definite recipe to make each mixture, because composition of mixture can vary.
Answer:
Compositional Layers
The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite.

Both too much and too little intake of zinc can impair the immune function. In addition to this, high intake of zinc can lessen the absorption of both iron and copper which are two of the most essential minerals needed by the human body.
Based on this:
<span>High zinc intakes can inhibit the absorption of copper is a true statement.</span>
