Dissolving in water is a physical change.
it is a chemical change because the stuuff dissolves so it is a chemical reaction.
It is a true chemical change because both the components loss their properties.
yes. its a physical change.
It is a chemical change.
Dissolving is a physical process.
Oxygen is a substance, an element out of the periodic system.
This is a chemical change.
It is a physical change.
A chemical change is a change involving making and breaking chemical bonds to form new chemicals. For example when wood burns the carbon and hydrogen in the cellulose react with the oxygen in the air, forming carbon dioxide and water. A physical change is one that the chemical changes states and no new chemicals are formed, like melting ice or dissolving salt in water.
This is a chemical reaction; oxygen is released.
Physical because it is still Oxygen. A chemical change results in a chemical equation and thus a new substance. No new substance = no chemical change. Liquefaction is a physical property.
Oxygen is a substance, an element out of the periodic system.
This is a chemical change.

That would be a chemical change.
This is a chemical change.
The process of burning in the presence of oxygen is that of a chemical change. It is a chemical change and not a physical change because the prodects do not have the same properties as the reactants.
This is a chemical reaction; oxygen is released.
Oxidation is a chemical process.
