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.
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 heating a wood splint a chemical or physical change?
Heating a wood splint is a chemical change. If this was done in something like a test tube, you will see many things occur that indicate this. First, you will see a werid kind of smoke, the splint turning into black stuff, and a really bad smell. Well the smoke is CO2 and the black stuff is ash from the burning. Because there is a new substance being made and the identity of the original substance(your splint) has changed, the reaction is chemical.
Is fizzing a chemical change?
There are signs that you can see when a chemical change takes place. It is true that fizzing or foaming is evidence that a chemical change may have occurred.
Can it be difficult to tell the difference between a physical and chemical change?
It is sometimes difficult to decide whether an observed change is physical or chemical because of its expression. Some reactions create subtle changes and some may appear to be physical or chemical until, upon closer observation externally or internally, it is actually turns out to be the opposite.
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 involves a change in a substance's chemical properties (characteristics that describe how it interacts with other substances).A physical change involves a change in a substance's physical properties(characteristics that describe certain features one can see with their 5 senses).
What must you know if a chemical change occurs?
fizzingcolor change (of course, this exempts artificial coloring)odorformation of precipitateproduction of gasformation of new substance (elemental bonding)
How is freezing water to make ice cubes a physical change?
There are 2 types : chemical change and physical change the substance has changed state, you can see the change so basically its visible
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.
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 changes during chemical change?
In a Chemical Change, atoms rearrange to form one or more new substance. They do this by breaking bonds and forming new ones.The identity of the substance undergoing the change is altered. In short: it depends on the chemical change.You would see a gas given off, the colour might change and it may change states that can not be turned back to what it was.hope I've answered your questio :)During a chemical change, the properties change and a new substance is formed. Temperatures change, colors change or smoke is present, and/or gas/bubbles are releasedA new substance is created and heat, light, or gasses are given off.Even though the persons answer is very well explained (down below) but I think you are looking for a more simple answer which is: Burning PaperA new chemical is formed. Evidence of this is cooling or heating of the samples as well as bubbles meaning a gas is formed.Vinegar and baking soda form a gas and it bubbles.Forms different substance.
Is heating a mixture a chemical or physical change?

What is a change to a material that does not change its composition?
The kind of change described is referred to as a physical change. Examples of physical changes include, but are not limited to, changing the temperature or state of a substance, changing the shape of a substance, and breaking a substance into smaller pieces. A change that alters a material's composition would be classified as a chemical change.
