It really depends. There is no definite combination that can change into a chemical change. A chemical change is basically a change where the molecules or particles inside the original substance changes its property or what it is.
Here are some examples:
Baking Soda and Vinegar
Iron rusting (its not iron, its rust after the change has gone)
Silver or copper tarnishing
Photosynthesis

Is melting snow a physical change or chemical change?
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
Is mending a broken bone a physical change?
Healing a broken bone involves a combination of physical and chemical changes. The bone undergoes physical changes as it reconnects and reforms its structure, while chemical processes occur to help repair and strengthen the bone tissue.
Is frying a chicken physical or chemical change?
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
What are two kind of changes in matter?
Two types of changes in matter are physical changes and chemical changes. Physical changes involve a change in appearance, such as a change in shape or state, without forming new substances. Chemical changes involve a rearrangement of atoms to form new substances with different chemical properties.
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
What are the changes that may accompany a chemical changes?
- a change in color -a change in odour -bubbling -a change of state (eg. solid to liquid, gas to liquid, etc.) either one or a combination of these things can indicate a chemical change.

What can chemical changes change?
Cooking food can cause chemical Changes
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
Are all physical changes accompanied by a chemical change?
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Is etching glass with acid a chemical or physical change?
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.

Is iron physical changes or chemical changes?
Iron is a chemical element, not a change.
Does smoke of a vehicle a physical or chemical change?
The smoke produced by a vehicle is a combination of physical and chemical changes. The combustion of fuel in the engine is a chemical change that produces gases, while the dispersal of these gases into the air involves physical changes such as condensation and diffusion.
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
