No, it's physical.
Sugar changing to alcohol is a chemical change.
CH3OH is the chemical formula of methanol, an alcohol - not a salt.
Mixing salt and water is a physical change, not a chemical change. The salt does not change its chemical composition when it dissolves in water, only its physical state.
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.
No. It is a physical change as the actual compound does not change, only its state does.
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.
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
this is a chemical change because you can't reyurn it back to salt
It is a physical change because the chemical composition of the salt and water does not change.
The dissolving of salt in water is a physical change because it does not result in a chemical reaction. The salt molecules are simply breaking apart and becoming dispersed in the water, but there is no change in the chemical composition of the salt.
Chemical
Yes, salt dissolving in water is a physical change because it does not involve a change in the chemical composition of the salt. The salt molecules are simply dispersed in the water, but they remain the same chemical substance.
