Is paper burning with a bright flame a reaction of exothermic or endothermic?
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.
Is paper burning with a bright flame endothermic or exothermic?
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.
What is an example of oxidation water evaporating sugar melting paper burning or all of the above?
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.
Why must paper be heated to start burning?
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.
Is burning a paper clip a chemical change?
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.
Is paper burning with a bright flame a exothermic reaction or endothermic reaction?
Reactions with oxygen (air) involved, like burning paper, are exothermic. Exception: formation of many nitrogen-oxygen compounds (NOx) are endothermic.
Is paper burning with a bright flame a reaction of exothermic or endothermic?
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.
What phrase best describes a exothermic chemical reaction?
A chemical change that gives off heat. Burning paper would be an example.
What is a basic example of a chemical reaction?
Burning paper.
Is paper burning with a bright flame exothermic?
Yes it would be exothermic
Is paper burning with a bright flame endothermic or exothermic?
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.
What is paper burning an example of?
A chemical reaction, and also a reaction in general.
What is the chemical reaction of burning a paper?
Burning is an oxydation reaction.
What is an example of oxidation water evaporating sugar melting paper burning or all of the above?
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.
What is a physical reactions?
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.
Why is paper burning a chemical reaction?
Burning is a sign of a chemical change
Is paper burning with a bright flame is endothermic or exothermic?
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.
