A chemist accidentally drops a fold wedding ring into a 150.0mL solution of 0.85M barium nitrate. The chemist doesn’t want to stick his bare hands in the solution but is nervous that his invaluable wedding ring will be gone soon! a) identify the oxidation state of N in Ba(NO3)2
b) predict the possible products of this reaction, then write and balance the chemical equation.
c) how many moles of barium nitrate were in the solution?
d) will the gold ring react with barium nitrate? in other words, is the Au more reactive than Ba? justify your answer.
