These are chemical reactions.
chemical
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
no
physical properties
Yes, burning involves a chemical reaction where a substance combines with oxygen to produce heat and light. This process often leads to the production of new chemical compounds with different properties than the original substance.
The chemical properties of an object show what a chemical change did to that substance.
A chemical reaction (change) results in a change in chemical properties.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
Yes
A chemical change occurs when a new substance is formed with different properties from the original substance. This change involves the rearrangement of atoms and the formation of new chemical bonds. It is typically irreversible.

A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
no
physical changes do not change the chemical properties of a substance
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
