Answer:
pH = 13.1
Explanation:
Hello there!
In this case, according to the given information, we can set up the following equation:

Thus, since there is 1:1 mole ratio of HCl to KOH, we can find the reacting moles as follows:

Thus, since there are less moles of HCl, we calculate the remaining moles of KOH as follows:

And the resulting concentration of KOH and OH ions as this is a strong base:
![[KOH]=[OH^-]=\frac{0.00576mol}{0.012L+0.032L}=0.131M](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E-%5D%3D%5Cfrac%7B0.00576mol%7D%7B0.012L%2B0.032L%7D%3D0.131M)
And the resulting pH is:

Answer:
water
water is the worlds best solvent cause it can melt many different things also it is called the "Universal Solvent"
Use a sieve to separate the water from the iron fillings and sand.
Use a magnet to separate the iron from the sand.
CaCl2(aq) + K2CO3(aq) → 2 KCl(aq) + CaCO3(aq)
