dont now look it up some where else.
Ethyl mercaptan
Evaporation of ethyl alcohol in a watch glass is a physical change, not a chemical change, because it does not alter the chemical composition of the alcohol. The process only involves a change in state from liquid to gas.
When ethyl alcohol evaporates, it is a physical change because the chemical composition of the alcohol remains the same. Evaporation is a process in which a substance changes from a liquid state to a gaseous state without undergoing a chemical reaction.
The methyl and ethyl groups, respectively.
No. The chemical structure of ethyl alcohol gas is the same as ethyl alcohol liquid.
The flammability of ethyl alcohol is chemical. It's a chemical property because if you change the molecular compound of ethyl, it will have a different flammability.
The chemical formula for ethyl alcohol is C2H5OH.
Molecular formula is C2H5CH3COO . Structural formula is CH3COOCH2CH3 .
C2h5oh
ethyl or grain
Evaporation of ethyl alcohol is a physical change. This is because evaporation involves only a change in the physical state of the substance from liquid to gas, without altering its chemical composition.
