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.

∙ 13y agoA chemical change results in a new product being formed. Example: oxygen and hydrogen are both gases but when they react with some activation energy they form the wonderful substance - water.
Some people think that a physical change can be reversed whereas a chemical change can not but that is not true. Many chemical reactions can be reversed.
A physical change means that there is no change to the nature of the substance. Example: melting, dissolving, grinding.

What is the diffrenece between a physical change and a chemical change?
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
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

Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Can you distinguish between a chemical and physical change?
they don't
What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
what is the difference between chemical change and physical changes?

What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
Differences between chemical and physical change?
A chemical change results in a change in chemical composition, while a physical change does not.
What is the difference between chemical from physical change?
a physical change is reversible but a chemical change is irreversible

What criteria are used to distinguish between a chemical and physical change?
One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.
Is the change between sodium and chlorine a physical change or chemical?
chemical
What is the difference between a chamical and physical change?
The diffence between chemical and physical is that ones chemical and ones physical!!
