Yes, burning paper is an example of an exothermic reaction because it releases heat and light energy.
When a piece of paper burns, the energy stored within the fibers of the paper is released as heat energy. This exergonic reaction produces more energy than it takes to perform.
Exothermic, for within an endothermic (situation) there would be a drop of temperature *excuse my spelling if you would* , therefore to continue burning it will need to absorb the heat, where as exothermic reactions energy will be released as heat.
An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.
Paper must be heated to start burning because heat is required to break down the cellulose fibers in the paper and initiate the chemical reaction of combustion. This process releases energy in the form of heat and light, causing the paper to continue burning once it has started.
Yes, burning a paper clip is a chemical change because it involves a chemical reaction where the paper clip combines with oxygen to produce new substances like ash and possibly some metal oxides.
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.

A chemical change that gives off heat. Burning paper would be an example.
Burning paper.

A chemical reaction, and also a reaction in general.
Burning is an oxydation reaction.

Answer:A physical reaction is a reaction whereby a new substance is not formed and is reversible.For example,folding of paper. Unlike a physical reaction,a chemical reaction is a process whereby a new substance is formed and is not reversible.For example,burning of paper.
Burning is a sign of a chemical change
Exothermic, for within an endothermic (situation) there would be a drop of temperature *excuse my spelling if you would* , therefore to continue burning it will need to absorb the heat, where as exothermic reactions energy will be released as heat.
