A:-      sn(s) =>  Sn +2(0.24 M) + 2e-
B:-     Sn +2 (0.87 M) +2e-  =>   Sn(s) 

solution will become more concentrated and solution B become less concentrated 

Sn(s)+ Sn +2(0.87 ) ----> Sn(s) + Sn  +2(0.24)
E  =   Eo  -   0.0592 / 2 * log   [   (0.24 / 0.87 ) ]
E  = 0.0   -   0.0592 / 2   *   log ( 0.275) 
( n=2 two electrons are transferred)

E =  -0.0296 *  ( - 0.560) 
E =  0.0165 volts

svlad2 [7]

Answer:

You'll experience a grater deviation

Explanation:

<em>You'll experience a greater deviation in your measurements, meaning your measures will have a bigger difference between them, and the greater these deviations the less accurate will be the measuring.</em> This happens mainly because you're not replicating the measurement with the exact same conditions, in one of them you'll have an extra mass from the water.

I hope you find this information useful and interesting! Good luck!

What mass of NH3 can be made from 35.0g of N2?
egoroff_w [7]
Formation of ammonia by nitrogen and hydrogen is habers process wher 28g N2 results in formation of 34g NH3
so 35g N2 will form 34*35/28=42.5g NH3 where it given that reaction takes place in excess of H2
N2+3H2 gives 2NH3
