Answer : The correct option is, 
Explanation : Given,
pH = 10
First we have to calculate the pOH.
Now we have to calculate the 
concentration.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
![4=-\log [OH^-]](https://tex.z-dn.net/?f=4%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=1.0\times 10^{-4}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.0%5Ctimes%2010%5E%7B-4%7DM)
Therefore, the concentration is, 
Answer:
Explanation:
An example of binary compund is ZnI2 is zinc iodide
I would say the answer is C
Answer:
Explanation By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.n:
