ethanol is a type of alcohol, in the oxygenated hydrocarbon class of compounds. when it combines rapidly with oxygen in a combustion reaction, the ethanol is used up, and with oxygen forms carbon dioxide and water. ethanol is quite literally gone, it is broken down and reformed into new products, which is the definition of a chemical reaction.

What single property do neon oxygen and ethanol have in common?
Physical ...they are all colorless
Formation of ethanol from glucose by yeast a chemical or physical change?
A chemical change
Is evaporation of ethanol a physical change?
Yes, evaporation, melting, and freezing are all physical changes. For it to be a chemical change, the substance would have to become a different substance. Evaporated ethanol is still ethanol, it is just in gas form.
What colour change will occur when potassium dichromate reacts with ethanol?
Potassium dichromate is orange and when it reacts with ethanol which is a primary alcohol it is going to oxidise it to form aldehyde which is colorless. so the color change is from Orange to Colorless. :)
How could one determine whether a colorless liquid contained ethanol or ethanol and sucrose?
That could be determined fairly easily by taste. Sucrose has a sweet flavor which ethanol does not.

physical change- the composition of the ethanol is not effected
Is ethanol boiling a chemical reaction?
no, boiling is a physical change
When ethanol is burnt and converted into carbon dioxide and water is that a chemical or physical change?
chemical
Grape juice turns to wine chemical or physical change?
Grape juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
Is evaporation of ethanol a physical change?
Yes, evaporation, melting, and freezing are all physical changes. For it to be a chemical change, the substance would have to become a different substance. Evaporated ethanol is still ethanol, it is just in gas form.
Why do Ethanol and dimethyl ether have different chemical and physical properties?
structures and functional groups.
