only when a change occurs and a new substance is formed
Chemical equations show what happens when a chemical change occurs. For example, in the combustion of Hydrogen(H2), water(H2O) is formed. The chemical equation for this reaction is: 2H2 + O2 -----> 2H2O This chemical equation shows that when H2 reacts with O2 , H2O is formed.
It is a chemical change.
Chemical change.
The product formed depends with the type of change that occurs whether it is a chemical or a physical change.

The ionic bond is formed during a chemical reaction.
When you burn wood a chemical change occurs.
only when a change occurs and a new substance is formed
only when a change occurs and a new substance is formed
when a substance undergoes a chemical change the original form cannot be recognized and it could get total new properties.
The substance formed in a chemical change is called Product.
