A 110.0-mL sample of a solution that is 2.7×10−3 M in AgNO3 is mixed with a 220.0-mL sample of a solution that is 0.11 M in NaCN. For Ag(CN)2−, Kf=1.0×1021. After the solution reaches equilibrium, what concentration of Ag+(aq) remains?

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

the role of the microscope world in creating new materials .
