which is an example of a chemical reaction?\npaper folded into tiny pieces\npaper burned and turned into smoke\npaper soaked in water\npaper shredded and turned into pulp
Answer
Brief Explanations:
A chemical reaction results in the formation of new substances with different chemical properties. Folding paper is a physical change as no new substance is formed. Soaking paper in water is also a physical change. Shredding paper into pulp is a physical change too. But when paper is burned and turns into smoke, new substances like carbon - dioxide and other combustion products are formed, which is a chemical reaction.
Answer:
paper burned and turned into smoke
