Answer the question using 5 complete sentences and the vocabulary terms; velocity, position, and distance
Explanation:
 
        
             
        
        
        
16 H + + 2Cr2O72- + C2H5OH → 4 Cr3 + +11H2O +2CO2
The reducing agent is C2H5OH
Explanation
reducing  agent is a substance that loses or donate electrons  in a chemical reaction. C2H5OH is the one which donate electrons in the above chemical equation.
 
        
             
        
        
        
Yes it could, but you'd have to set up the process very carefully.
I see two major challenges right away:
1).  Displacement of water would not be a wise method, since rock salt 
is soluble (dissolves) in water.  So as soon as you start lowering it into 
your graduated cylinder full of water, its volume would immediately start 
to decrease.  If you lowered it slowly enough, you might even measure 
a volume close to zero, and when you pulled the string back out of the 
water, there might be nothing left on the end of it.
So you would have to choose some other fluid besides water ... one in 
which rock salt doesn't dissolve.  I don't know right now what that could 
be.  You'd have to shop around and find one.
2).  Whatever fluid you did choose, it would also have to be less dense 
than rock salt.  If it's more dense, then the rock salt just floats in it, and 
never goes all the way under.  If that happens, then you have a tough 
time measuring the total volume of the lump.
So the displacement method could perhaps be used, in principle, but 
it would not be easy.
        
             
        
        
        
Frequency. 
The equation to find the velocity of a wave length is: 
v=fλ
V stands for velocity 
F stands for frequency 
λ stands for wavelength
