They send warmer and colder temperatures to different places (I may be wrong so you should just pick the answer above mine)
        
             
        
        
        
To determine the pH of a weak base, we use the equation:
pH = 14 + 0.5 log Kb
Therefore, 
pH = 14 + 0.5 log 3.25
pH = 14.26
A weak base is a base which does not fully dissociates into ions when in solution. The solution would contain cations, anions and the compound itself. Hope this helps.
        
             
        
        
        
Answer:
Mass of solvent is 1127.3 g
Explanation:
NaOCl → 3.62%
This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:
100 g of bleach solution have 3.62 g
1169.6 g of bleach solution may have (1169.6  . 3.62) /100 = 42.3 g
42.3 g is the mass of NaOCl in the solution
Mass of solution = Mass of solvent + Mass of solute
1169.6 g = Mass of solvent + 42.3 g
1169.6 g - 42.3 g = Mass of solvent → 1127.3 g
 
        
                    
             
        
        
        
Combinations of different metals form alloys. An alloy composed by mercury and other metal (or metals) forms amalgam. When a true alloy is formed, the component metals are mixed together at a temperature which is greater than the melting point of all of them.Apr 7, 2017
 
        
             
        
        
        
Answer:
0.954
