Answer

a) mixture, physical change b) compound, chemical change c) Mixture and physical change

Work Step by Step

a) Physical change because The orange liquid is a mixture. Distillation is the process of boiling (evaporating) a liquid and then cooling the gas in a separate area. The process is a physical change. b) The properties of this solid (colorless, and crystalline) do not appear to be the properties of the two or more components. Thus, this is a compound. It is chemical change because the solid is decomposed, result to a new substance. c) Mixture because tea is composed of water and tea leaf. It is physical change because the sugar does not create drastic changes in the material. The sugar simply floats around and sweetens the liquid proportionately.
