The correct answer is option E.
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Mathematically written as:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The pOH of the solution is defined as negative logarithm of hydroxide ions concentration in a solution. Mathematically written as:
![pOH=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D)
The sum of ph and pOH is equal to 14.
pH + pOH = 14
A solution has a pH of 4.20.
![pOH=9.8=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D9.8%3D-%5Clog%5BOH%5E-%5D)
![[OH^-]=1.58\times 10^{-10} M\approx 6.0\times 10^{-10} M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.58%5Ctimes%2010%5E%7B-10%7D%20M%5Capprox%206.0%5Ctimes%2010%5E%7B-10%7D%20M)
Hence, the correct answer is option E.
The bacteria are chemoautotrophs. These microorganisms make use of molecules that are inorganic for energy and using carbon dioxide for carbon source. The process of obtaining energy is called chemosynthesis which uses molecules like hydrogen sulfide, ferrous iron, ammonia and the like.
6.023*10^23 of any given particle, be it an atom or a molecule.
It can allow the molecule (like water) to be polar because it has a negative and positive side to it (oxygen holds the negatives tight causing the hydrogens to be positive).
Answer:
growth medium
Explanation:
The pathogenic bacteria are the bacteria which causes diseases. They may include fungi, worms, protozoa, viruses, bacteria, etc.
The bacterial pathogens are made to grow with the help of a growth medium which is developed to optimize the antigen's yield and also it maintains the integrity of the pathogenic bacteria.
