Ethanol is a pure substance, but it is rare to encounter it pure. Laboratory alcohol usually contains small amounts of water and methanol. Alcoholic drinks contain large quantities of water, as well as flavourings.
Neither. C2H2 is a compound (pure substance) so it is not a mixture at all. Hint: mixtures don't have chemical formulas.
Sodium chloride (table salt) is a pure substance because it is a compound made up of sodium and chloride ions in a fixed ratio. It is not a mixture because it cannot be separated into its components by physical means.
No. Ethanol is also alcohol. Ethanol is a compound. It is not a mixture.
Sulfur is not a mixture at all. It is a pure substance. Specifically it is an element.
It is not a mixture at all. It is a pure substance, an element to be specific.
Ethanol is not a mixture at all. It is a compound and therefore a pure substance.
It is a pure substance.Added:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
Grain alcohol is a compound known as ethanol and so is a pure substance, but it is almost never found in pure form.
Pure ethanol, CH3CH2OH, is an pure organic compound and not a mixture
Rubbing alcohol is a solution. What you buy labeled as rubbing alcohol is a mixture of various concentrations of methanol, ethanol, isopropanol, and water, usually around 70% alcohol and the rest water.
Ethanol is a substance. CH3CHOH

pure substance?

(This is what you get when buying a bottle pure ethanol)rubbing alcohol is a mixtureIf you were to take 'alcohol' into a more specific definition an alcohol is really a hydrocarbon with the functional groupSo if it were, well i would say, 100% ethanol then it would be a compound.
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
No, it is a mixture; rarely a drug is a pure substance.
No a mixture is by definition not a pure substance.
