You have a mixture of KCI, BaCO3, and SiO2, From the following, select the steps that would allow you to separate and isolate the KCI and SiO2 from the mixture. Step 1 A. Add a solution of 0.1 M AgNO3(aq), stir, and decant the supernatant Step 2 three times. Step 3 B. Heat the residual solid SIO2 to remove the water. C. Add a non-polar solvent, stir, and decant the supernatant three times. Evaporate the water from the combined supernatant. D. Add water, stir, and decant the supernatant three times. Evaporate the water from the combined supernatant. E. Heat the mixture to sublime one of the components. F. Add a solution of 1 M HCI, stir, and decant the supernatant three times.
