The answer is D. Effective collisions lead to chemical reactions!
        
                    
             
        
        
        
Answer:
Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.

 I think it's easiest to find the pOH from the given [OH-] first. 
-log(1x10^-5) 
pOH=5 
Then find the pH. 
pOH+pH=14 
5+pH=14 
pH=9 
Then find the [H+] using the pH. 
antilog(-9) (if you dont have an antilog button use 10^-9) 
[H+]=1x10^-9
 
        
                    
             
        
        
        
Answer is either B or all of the above. “G” is not an element on the periodic table. If it’s not a typo, then the answer is B.
