chemical change = chemical reaction. ( the composition of matter always changes).
In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.

Is heating sulfur a physical or chemical change?
Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
Is clouds forming in the sky a chemical or physical change?
Original answer is INCORRECT. Clouds forming in the sky is a physical change because a chemical change requires a change in the chemical composition of a material and the H2O, no matter a solid liquid or gas, is always H20.
Does a compound have a chemical composition?
Yes
Is color change a physical or chemical change?
It depends. In most cases, it is a chemical change as the different colored species have different chemical structures. However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
What is fixed composition?
Today the laws of definite proportions and multiple proportions, applied to chemical compounds, are considered as not genarally valid.Many mixtures (not all !) have a fixed composition depending on the specific application and recipe.
What happens to the composition of matter when matter undergoes a chemical change?
A chemical change involve a change of composition.
What describes any change in matter that does not affect the chemical composition of the material?
Physical change, as change in state.
Is temperature a chemical change?
Temperature change is not a chemical change.
Does a phsical change or chemical change affect the matter in an object?
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
What changes with a chemical change?
chemical changes affect the chemical properties as well as composition of matter , that result in the formation of a new substance.
How does a chemical differ from a physical change?
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
