The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high ![\rm [H]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5D)
will have:
Option B. A low ![\rm [OH ^{-}]](https://tex.z-dn.net/?f=%5Crm%20%5BOH%20%5E%7B-%7D%5D)
and a high 
This characteristic can be explained as:
- The concentrations of
![\rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D)
and are inversely dependent on each other so when the concentration of raises then the concentration of drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
![\rm pH = \rm - log \rm [H^{+}]](https://tex.z-dn.net/?f=%5Crm%20%20pH%20%20%3D%20%5Crm%20-%20log%20%20%5Crm%20%5BH%5E%7B%2B%7D%5D)
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.

Co(NO3)2 isthe right answer
Explanation:
hope it helped u a lot
Metallic bonding
The particles in a metal are held together by metallic bonds.
High melting and boiling points
Metallic bonds are strong and a lot of energy is needed to break them. This is why metals have high melting points and boiling points.
Conducting electricity
Metals contain electrons that are free to move in the metal structure, carrying charge from place to place and allowing metals to conduct electricity well.
Metallic bonding - Higher tier
Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons.
Answer:
A chemical reaction happens when substances break apart or combine to form one or more new substances.

Answer:
You will need 12 moles of F2 if you want to make 8 moles of AlF3.
Explanation:
It takes 3 moles F2 to make 2 moles of AlF3 (this will be our mole ratio)
2 moles AlF3/3 moles F2 =8 moles AlF3/x moles AlF3.
x=12 moles AlF3
