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:
Shiny, conduct heat and electricity well, malleable.
Explanation:
Answer:
Aquifer
Explanation:
Instead of snowcapped mountains that store water in advance of warmer temperatures, most of our drinking water comes from underground "mountains" of porous materials called aquifers which are replenished by rain. The Biscayne Aquifer is South Florida's lower east coast's primary source of fresh water.
Jenny puts the ph paper and lines it up PH SCALE to find how strong the solution.
