When washing the solids after the reaction with zinc metal, what are you removing? Choose... (5pts) Based upon the percent yield you calculated, what is one source of error, and the resulting of that error in your experiment. Select the option corresponding to the following choices When decanting, some solid was lost, resulting in less copper recovered and a lower % yield When decanting, some solid was lost, resulting in more copper recovered and a higher % yield When drying over the steam bath, did not let the sample dry completely, resulting in a higher mass of copper recovered, and a higher % yield. When drying over the steam bath, did not let the sample dry completely, resulting in a lower mass of copper recovered, and a lower % yield.
