Afirst-order reaction has a rate constant of 0.33 min-1. it takes min for the reactant concentration to decrease from 0.13 m to 0.088 m

The first order reaction is when the rate of the reaction is directly proportional to the concentrations of one of the reactants.
if the reactant whose concentration determines the rate - N
rate equation is 
rate = k [N]¹
where k - rate constant 
the differential equation is as follows;
[N] = [N₀] e^ (-kt)
where N - concentration after t minutes
N₀ - concentration when t = 0 minutes 
k -rate constant 
t - time taken in minutes 
substituting the values given following equation is obtained 
0.088 m = 0.13 e^ (-0.33 *t)
e^ (-0.33 *t) = 0.088/ 0.13
       -0.33t      = ln 0.676
       - 0.33t     = -0.39
                t = 1.18 minutes
it takes 1.18 minutes for reactant concentration to decrease from 0.13 m to 0.088 m

It was necessary to redeem the world and he knew that his son was the only way

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
