Answer:
Concentration of hydrogen ion, ![[H^+]=5.0118*10^{-6} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D5.0118%2A10%5E%7B-6%7D%20M)
Explanation:
pH is defined as the negative logarithm of hydrogen ion's concentration.
The lower the value of pH, the higher the acidic the solution is.
The formula for pH can be written as:
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
Given,
pH of the saliva of Marco = 5.3
To calculate: Hydrogen ion concentration in the saliva
Thus, applying in the formula as:
![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![5.3=-log[H^+]](https://tex.z-dn.net/?f=5.3%3D-log%5BH%5E%2B%5D)
So,
![log[H^+]=-5.3](https://tex.z-dn.net/?f=log%5BH%5E%2B%5D%3D-5.3)
![[H^+]=10^{(-5.3)}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B%28-5.3%29%7D)
![[H^+]=5.0118*10^{-6} M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D5.0118%2A10%5E%7B-6%7D%20M)

<span>Copper II Sulfate- Cu 2+ and a sulfate SO4 2- add together nicely to make CuSO4. </span>
Answer:
The iron core, copper wire, and an electricity source.
Explanation: Me
1.) protons neutrons and electrons
2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons
3.) is an imbalance if electric charges within or on the surface of a material
4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair
5.) you might have to answer that on your own but if you don’t want to here’s my experience
One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up
