Question

State reasons for the following statement: Burning of paper is a chemical change.

Answer 1

• The act of burning a substance in the presence of oxygen is referred to as the combustion process. Because it involves a chemical change in the substance, burning paper is called a combustion reaction.
• This is because when we burn a piece of paper, it undergoes the combustion reaction, which causes the substance's state to transition from solid to liquid to gaseous.
• As a result, burning paper is regarded a chemical change since the paper transforms into ashes and gas emissions are released.
• When paper is burned, some gases are released, turning the white paper into a brownish black ash.
