Answer:
chemists created medicine to help fight leukemia.
Explanation:
Answer:
11
Explanation:
Moles of KOH = 
Volume of water = 10 liters
Concentration of KOH is given by
![[KOH]=\dfrac{10^{-2}}{10}\\\Rightarrow [KOH]=10^{-3}\ \text{M}](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5Cdfrac%7B10%5E%7B-2%7D%7D%7B10%7D%5C%5C%5CRightarrow%20%5BKOH%5D%3D10%5E%7B-3%7D%5C%20%5Ctext%7BM%7D)
![[KOH]](https://tex.z-dn.net/?f=%5BKOH%5D)
is strong base so we have the following relation
![[KOH]=[OH^{-}]=10^{-3}\ \text{M}](https://tex.z-dn.net/?f=%5BKOH%5D%3D%5BOH%5E%7B-%7D%5D%3D10%5E%7B-3%7D%5C%20%5Ctext%7BM%7D)
![pOH=-\log [OH^{-}]=-\log10^{-3}](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E%7B-%7D%5D%3D-%5Clog10%5E%7B-3%7D)
So, pH of the solution is 11

Hazardous materials are grouped into classes identifying their similarities in composition and structure.
<h3>Why hazardous materials are grouped into classes?</h3>
The hazardous materials are grouped into classes in order to tell us about the severity of hazard and it is done on the basis of similarity in composition.
So we can conclude that hazardous materials are grouped into classes identifying their similarities in composition and structure.
