yes because it changes the physical properties of it as a paper by burning
They are similar because you are producing a chemical change in both, making new substances.
because they oxygen
Burning a paper. Any change where you can't go back to the original item is a chemical change. You can't go from ashes back to a paper. Crumpling a piece of paper is a physical change because it's still a piece of paper.
The candle burning is a chemical process.

the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
Burning is a chemical change.
Cheimical change
Because you can't put it back together. Imagine burning a piece of paper, there is no way that you can get that piece of paper back. Burning that piece of paper was a chemical change because you changed the chemical properties of the paper. Crumpling or cutting the paper doesn't change the molecular structure of the paper, so it is a physical change.

no, a chemical change is when something turns into something else. as an example burning paper is a chemical reaction because the paper turned into ashes and changed. but if you rip a piece of paper in half its still a piece of paper right. did that answer your question
