Question
The properties of a mixture are typically averages of theproperties of its components. The properties of a compound maydiffer dramatically from the properties of the elements thatcombine to produce the compound. For each process describedbelow, state whether the material being discussed is most likely amixture or a compound, and state whether the process is a chemicalchange or a physical change. A. An orange liquid is distiled, resulting inthe collection of a yellow liquid and and a red solid. B. A colorless, crystalline solid isdecomposed, yielding a pale yellow-green gas and a soft, shinymetal. C. A cup of tea becomes sweeter is sugar isadded to it.

a) mixture; physical change it is a mixture of the red solid dissolved in the yellow liquid.The yellow liquid has a higher boiling point, so it is distilled.This is a physical change B) compound, chemical change the key word is decomposed; the gas molecules are free from theirbonding with the metal. C) mixture, physical you are dissolving sugar into a aqueous solution. No chemical bondsform/break. Just a physical process.
