Can i light a Bunsen burner with burning paper?
No, it is not safe to light a Bunsen burner with burning paper as the paper may not provide a consistent flame and could introduce contaminants to the burner. It is recommended to use a striker or a lighter to ignite the Bunsen burner's gas flame.
What is the burning and chemical test for rayon?
The burning test for rayon involves holding a small piece of the fiber to a flame. Rayon will ignite easily and burn rapidly, producing a bright flame and a smell similar to burning paper. The chemical test for rayon can include dissolving it in sodium hydroxide, which will cause rayon to disintegrate, as it is a regenerated cellulose fiber. Both tests help differentiate rayon from other fibers, such as polyester or acrylic, which have different burning and solubility characteristics.
Can you light a Bunsen burner with a burning piece of paper?
No, it is not safe to light a Bunsen burner with a burning piece of paper because it can lead to an uncontrolled flame and potential accidents. It is recommended to use a striker or a lighter specifically designed for lighting Bunsen burners to ensure proper control of the flame.
What phrase best describes a exothermic chemical reaction?
A chemical change that gives off heat. Burning paper would be an example.
Is the burning of paper a spontaneous reaction?
No, the burning of paper is not a spontaneous reaction as it requires an external heat source to initiate the combustion process. Once the paper is exposed to sufficient heat, it undergoes a chemical reaction with oxygen in the air to produce heat and light energy, resulting in the flame and smoke that we observe during combustion.
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.
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.
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.
Is paper burning with bright flames exothermic or endothermic?
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.
Is burning paper a example of a exothermic reaction?
Yes, burning paper is an example of an exothermic reaction because it releases heat and light energy.

What would we observe if we put a plastic cap on a piece of paper over a burning flame?
we would the cup and the paper burn like when you put news paper on a bbq.
When you hold the paper over burning candle why it moves up?
When you hold the paper over a burning candle, the air around the flame heats up and rises, creating an area of low pressure. This causes cooler air from the surrounding area to rush in towards the flame, which results in the paper being drawn upwards due to the movement of air.
Can you light a Bunsen burner with a burning piece of paper?
No, it is not safe to light a Bunsen burner with a burning piece of paper because it can lead to an uncontrolled flame and potential accidents. It is recommended to use a striker or a lighter specifically designed for lighting Bunsen burners to ensure proper control of the flame.
You can boil water in a paper cup over a direct flame without burning it How can you explain that?
This is only how i explained it to myself after i did the experiment, so it might not be right. Burning is the result of a combustion reaction, and combustion reactions require a certain amount of activation energy to start. When the paper is in contact with water, the energy from the open flame that would usually start the combustion reaction is transferred to the water before the paper can ignite. This raises the temperature of the water and it will eventually reach boiling point. Now when all the water has evaporated, then the cup burns because there is nowhere left for the heat to be transferred to.
