Answer 1

You're going to probably get a range of opinions on this depending on your definition of substance.

soil. - M - you'll have organisms, organic matter & water
coffee. - in what form?
alcohol.- M
cake batter - M.
Soup - M
Salt Water - M - range of dissolved solids
Ice Cream - M
Nitrogen - S (I think)
Eggs - M - proteins, fat & water
Blood - M - white & red blood cells, plus platelets
Table Salt - M
Nail Polish.- M
Milk - M - fat, vitamins, water & protein
Cola - M

Answer 2

The only item on the list that is clearly a "substance" is nitrogen, as it is elemental the way it's named.

Alcohol may or may not be a substance, depending on what it refers to. PURE alcohol would be a substance, since it would be molecularly pure. However, "alcohol" in typical usage refers to things like rubbing alcohol, which is mixed with water, or liquor, which usually includes colorants and flavorants.

soil -- sand, organic matter
coffee -- coffee bean, so has plant cells
cake batter - flour, eggs, water
soup -- flavorant, water
salt water -- salt, water
ice cream -- milk cream, flavorant, colorant
eggs -- proteins, fats, etc.
blood -- blood cells, blood plasma, hormones, enzymes
nail polish -- colorant, solvent, latex
milk -- water, fat, caseins
cola -- water, carbon dioxide, colorants, flavorants


Table salt often contains iodine and/or silica
