Polymerization is not a property; it is a type of chemical reaction.
When atoms are rearranged into different combinations of compounds Physical Reaction?
The rearranging of atoms to form new combinations is called "chemical reaction", and the "new combinations" are called "compounds.
Is a substance freezing a chemical reaction?
No, freezing water is not a chemical reaction. It is a physical change which water undergoes at temperatures below 0oC. At higher temperature the ice melts back to water again.
When a substance change from one physical form to another you say the substance has had an?

What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
Is a substance freezing a chemical reaction?

What happens to two substances when they form a mixtures?
It is a physical process, not a chemical reaction.
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
Is burning coal a chemical or physical reaction?
It is a chemical reaction. The coal (which is mostly carbon) reacts with oxygen to form carbon dioxide.
Is something that reacts with water to form gas a chemical or physical?
Chemical because if the reaction is production of gas, then it's a chemical.
