Element is the purest, single form of chemicals, ie Iron-Fe, Oxygen-O, Hg...\nCompound is the result of the reaction of different chemicals, ie Carbon dioxied CO2... Sometimes gases of one element can be called compound, ie Hydrogen-H2...\nMixture is the combination of two or more chemicals, in which the reaaction does not take place. For instance, Iron-Fe and Copper-Cu can be mixed together, but they would not react to each other.\nBase Salt - mostly is NaCl, CaCl2... - Compound\nStainless Steel - mixed between Iron-Fe, Lead-Al and others - Mixture\nTap Water - assume it is pure H2O - Compound\nTable Sugar - usually is C6H12O6 or C8H12O11 - Compound\nVanilla Extract - another result of sugar formular - Mixture of Compounds\nButter - result of processing milk - Mixture of Compounds

Air is is mainly nitrogen  and oxygen with a mixture of other gases.\nmilk is proteins, fats, lactose, and various vitamins and minerals.\nBronze is various alloys of copper and tin and some bronze will contain other metals too.\nSugar is a sweet cystalline or powder derived from sucrose and lactose obtained mainly from sugar cane and sugar beets.\nSo in all technicality the answer would be E. no of the above.

HCl - Clear colourless to light-yellow liquid\n\nBromine - gas/liquid: red-brown solid: metallic luster\n\nBromine is the only liquid nonmetallic element at room temperature and one of five elements on the period table that are liquid at or close to room temperature. The pure chemical element has the physical form of a diatomic molecule, Br2. It is a heavy, mobile, reddish-brown liquid, that evaporates easily at standard temperature and pressures in a red vapor (its color resembles nitrogen dioxide) that has a strong disagreeable odor resembling that of chlorine

Salt - sodium chloride.\n\nIf you need something a bit more unusual, I believe there is imitation salt which is potassium chloride.

the first 10 are right, except you spelled "berilium" wrong, it should be "Beryllium" elements 11-20 are: Sodium, Magnesium, Aluminum, Silicon, Phosphorus, Sulfer, Chlorine, Argon, Potassium, and Calcium
