I. Classify the following as homogeneous mixtures, heterogenous mixtures, elements or compounds. a.water - compoundb.shampoo - homogeneous mixturec.dry soup mix - heterogeneous mixtured.salt water - homogeneous mixtureII.Mixtures can be separated into their components by taking advantage of differences in the chemical properties of the components. Why might this separation method be less convenient than taking advantage of differences in the physical properties of the components?
Separation by physical properties would be fairly easy compared to separation by the chemical properties. You could use distillation to separate based on boiling point, a molecular seive to separate by size, or a GC column to separate by polarity.
Choose one from the following: -a chemical property involves a chemical change so that you no longer have what you had. -The chemical properties of the components of a mixture are too similar to each other. -Chemical properties are not as apparent as are physical properties. -The chemical properties of the components of a mixture are too different from each other. III. Classify the following as element, mixture, or compound a.table salt - elementb.stainless stell - mixture (actually an alloy)c.table sugar - compoundd.aluminum - elemente.ice - compound
Here is an additional question that I am having trouble with.If it's not too much trouble could you please help me with thisone as well?
-Many dry cereals are fortified with iron, which is added to thecereal in the form of small iron particles. How might theseparticles be separated from the cereal?
Choose one from the following.a. Blend the cereal to a fine consistency and pass through a filter.b. Add water and the iron particles will float to the top.c. Collect the iron filings with a magnet.d. Heat the cereal so that the iron particles melt and thereby coallesce.
