Is oxidation an example of a chemical change?
Oxidation is a chemical change. This is a chemical change because it has formed into a new substance and cannot change back! The chemical identity of the metal has been changed and will require some other change to change it back.
What is the différence between a chemical change and a physical change?
A chemical change involves the formation of new substances with different chemical properties, while a physical change involves a change in the appearance or state of a substance without forming new substances. Chemical changes are usually irreversible, while physical changes are typically reversible.
a change in the chemical properties of substance results in a?
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
Is salt dissolving in water physical change?
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.
Is heating a wood splint a chemical or physical change?
Heating a wood splint is a physical change because it does not change the chemical composition of the wood. The heating only affects the physical state of the wood, causing it to undergo a reversible change in temperature and possibly shape.
When you see stuff is that a chemical change?
This question is extremely general (no offense) but if by you mean "see stuff" you mean producing a new substance, then yes, it is a chemical change.
What is the difference between a phisical change and a chemical change?
A physical change is one you can see. It changes the size, shape, or color of something. A chemical change is one that changes the composition of something. Basically, when a substance is changed into a different substance.
What is the differences between chemical and physical change?
A chemical change results in the formation of new substances with different properties, while a physical change alters the state or appearance of a substance without changing its chemical composition. Chemical changes involve the breaking and forming of chemical bonds, whereas physical changes involve changes in the physical state, such as melting, freezing, or evaporating.
Is it chemical or physical change if you leave your bicycle out in the rain and it rusts?
It is a chemical change because the metal of the bicycle reacts with oxygen and water to form rust, which is a different substance from the original metal.
What must you know if a chemical change occurs?
To determine if a chemical change has occurred, you must observe one or more of the following: the formation of a precipitate, a change in color, the release of a gas, or a change in temperature. Additionally, the chemical composition of the substances involved must have changed to qualify as a chemical change.
Is composting leaves a physical or chemical change?
Chemical.
If a firefly glows in the dark is that a chemical or physical change?
It's a physical change. A chemical change is when a new substance is formed. A physical change is when something looks, feels, tastes, or smells different, but it's the same substance. You see the firefly is always glowing, it's just the fact that the human eye cannot see it because it is being over powered by the light of the Sun; but it's still the same firefly.

What changes during chemical change?
During a chemical change, the chemical composition of the substances involved is altered. This can result in the formation of new substances with different properties from the original ones. The change is usually accompanied by the release or absorption of energy.

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.
