suppose you had a mixture of silver iodide, potassium nitrate, ethyl alcohol, and water. if you wanted to recover each of the compenents in pure form, which methods: decantation after sedimentation, decantation after centrifugation, or filtration would you use? Explain how you would carry out this separation and recovery, indicating exactly what components you have at each step of procedure.

An organic liquid is a mixture of methyl alcohol (CH3OH) and
ethyl alcohol (C2H5OH). A 0.220-g sample of the liquid is burned in
an excess of O2(g) and yields 0.380 g CO2(g) (carbon dioxide).
Set up two algebraic equations, one expressing the mass of
carbon dioxide produced in terms of each reagent and the other
expressing the mass of sample burned in terms of each reagent.
