Yes. ETOH is ethanol alcohol, the drinking kind.
Alcohol, you mean ethanol (spirit) I suppose, is C2H5OH Water : H2O
If you mean ethanol the chemical formula is C2H5OH.
I assume that by "boils faster" you really mean "boils at a lower temperature", and that by "alcohol" you mean "ethanol". Ethanol has a lower boiling temperature than water at standard pressure. However, a mixture of ethanol and water boils lower than either by themselves do. This is called an "azeotrope" and it happens for ethanol/water mixtures at about 95% ethanol, which is why it's essentially impossible to get ethanol to more than 190 proof by distillation alone.
Ethanol (the kind of alcohol that people drink).
Depends. What do you mean with "treated with ethanol"? In bread making, ethanol (or ethyl alcohol) are produced without the intention of making wine. so it's halal.
The answers will depend on whether you mean a drop of alcohol or a bottle or a vat. Furthermore, it will depend on the type of alcohol: methanol, ethanol, propanol, etc.
there are many types of alcohol so I'm going to assume you mean ethanol (the type found in alcoholic beverage) ethanol is C2H5OH (water is H2O )
Sodium chloride is very low soluble in ethanol: only 0,65 g/L at 20 0C.
By alcohol I assume you mean an alcoholic drink. Ethanol is the chemical that burns in such drinks, unless you're drinking moonshine in which case there may be some methanol.
By "hand alcohol", do you mean rubbing alcohol? If so, then rubbing alcohol is a mixture of 70% isopropyl alcohol (2-propanol) and water, while drinking alcohol is a mixture of water, ethanol, and various flavorings in varying proportions... vodka, for example, is typically around 50% ethanol. 2-propanol is poisonous. One other type of alcohol that's commonly encountered is "wood alcohol", which is methanol. Methanol is also poisonous. Finally, denatured alcohol is ethanol which has been made undrinkable by the addition of foul-tasting or poisonous substances. (Denatured alcohol is taxed by the government at a much lower rate.) There are several different official formulas that can be used to denature ethanol depending on exactly what it's being used for. Some of them include things like methanol, 2-propanol, gasoline, or even benzene... which is a carcinogen. If you were talking about the alcohol in hand sanitizers, it probably falls into this category. Technically speaking ethanol is itself poisonous, but much less so than the other substances named above.
Alcohols like ethanol are consisting mostly from hydrogen and carbon(C2H5OH, ethanol formula). And they react with the oxygen in the air. Out of that reason alcohol becomes more filled with water after it is getting burnt(oxygen+2hydrogen+fire reaction=water).
alcohol does freeze, but at a much lower temparture than water. It has a freezing point of -117 F, which is much colder than a conventional freezer.
