Alcohol is both a substance and a chemical. Substances are any material, chemicals are any material. Both can be made up of a single pure element or mixture of elements. Mixture in this case can mean either a chemically bonded mixture like table salt where the sodium and chlorine join to make new molecule of sodium chloride, or an alloy where the materials are held together by mechanical forces. In alcohol carbon, hydrogen and oxygen unite to form a new molecule, but it is usually mixed with water as a mechanical mixture.
What else can I help you with?
Is a soluble in alcohol a physical or chemical property?
Solubility is considered as a chemical property.
What are the differences between isopropanol and isopropyl alcohol, and how do they compare in terms of their chemical composition and uses?
Isopropanol and isopropyl alcohol are the same chemical compound, with isopropyl alcohol being the more common name. They have the same chemical composition, which is C3H8O. Isopropyl alcohol is commonly used as a solvent, disinfectant, and cleaning agent, while isopropanol is used in the same way but is less commonly referred to by that name.
Is Alcohol vaporizing physical change or chemical change?
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.
Is evaporating alcohol a chemical change?
No. It is a physical change as the actual compound does not change, only its state does.
Is ethyl alcohol in a watch glass a physical or chemical change?
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.

Why is burning alcohol a chemical change?
Burning alcohol is a chemical change because it involves a chemical reaction where the alcohol molecule is broken down into different substances (such as carbon dioxide and water) with new properties. Energy is released during the reaction, and the composition of the alcohol is permanently altered.
When ethyl alcohol evaporates is it a chemical or physical change?
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.
When alcohol evaporates is that a chemical or physical change?
Physical; from liquid to gas, but it's still alcohol.
Is sugar dissolving in alcohol a chemical reaction?
No, sugar dissolving in alcohol is a physical process known as dissolution. In this process, the sugar molecules are dispersed in the alcohol molecules, but the chemical composition of both substances remains the same.
Is rubbing alcohol a mineral?
No, rubbing alcohol is not a mineral. Rubbing alcohol is a liquid solution made up of isopropyl alcohol and water. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure.
Is mixing flour and rubbing alchohal a physical or chemical?
Mixing flour and rubbing alcohol is a physical change. In this process, the flour and rubbing alcohol retain their individual properties and can be separated again. There is no chemical reaction occurring, as the composition of the flour and the rubbing alcohol remains unchanged.
Does freezing alcohol change its molecular structure?
No because physical states of matter changes are physical changes. they are not chemical changing meaning it is still alcohol, just frozen.
