Answer:
The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Explanation:
The H⁺ concentration of a solution is exponentially related to its pH value:
![\rm [H^{+}] = 10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D)
.
For lemon juice:
![\rm [H^{+}] = 10^{-2.0} = 0.01\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-2.0%7D%20%3D%200.01%5C%3B%20M)
.
For stomach acid:
![\rm [H^{+}] = 10^{-1.0} = 0.1\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-1.0%7D%20%3D%200.1%5C%3B%20M)
.
Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
That is true, the potential energy they possessed at the airplane door would be converted to kinetic energy. And if they driver is high up, he has further to fall. As the skydivers jump, the energy would be converted to kinetic energy.
Hello, I don’t see the options
The correct answer is option a, that is, it gets broken down.
A set of metabolic reactions and procedures, which occurs in the cells of organisms to transform biochemical energy from nutrients into ATP, and then discharge waste components is known as cellular respiration. At the time of cellular respiration, a molecule of glucose gets dissociated slowly into water and carbon dioxide. With it, some of the ATP is generated directly in the reactions, which transform glucose.
Charcoal is the sample of this drawing medium have been dated back to 30,000 BCE and is denoted as option B.
<h3>What is Charcoal?</h3>
This is referred to a black carbon residue which is heated in insufficient oxygen to give it a light weight.
It is used for drawing and has been in existence for as long as 30,000 BCE hence the reason why it is the most appropriate choice.
