Copper can be identified in at least three different ways in this experiement. Write a balanced net ionic equation and describe one of the ways for which Cd2+ will interfere with the determination of copper.
Compute the molar heat capacity of mercury and the specific heat capacity of mercury.
the absorbance of the solution was found to be .5528. Based on the calibration curve of Y=26.1x + .081 (where absorbance is on y axis and concentration of product C is on the x axis) determine the equilibrium concentration of C, then using an ICE ..
