Answer:
The correct option is D
Explanation:
From the question we are told that
The pH of the aqueous solution is 
The isoelectric point is 
From the data given we see that the
is below
So the protein will have a net positive charge
I'm almost certan it's west but if not let me know fam. :)
No, a theory is the answer
Reaction
2AgNO₃ + Cu ⇒ Cu(NO₃)₂ + 2Ag
mol silver (Ag): 95.3 : 108 g/mol = 0.882
mol copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441
mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants
mol Cu = 0.441
mass Cu = 0.441 x 63.5 g/mol = 28 g
mol AgNO₃ = 0.882
mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g
