Is burning octane exothermic or endothermic?
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is wax in a candle burning an exothermic process or endothermic?
Burning a candle is an exothermic process because it releases heat energy. The chemical reaction between the wax and oxygen produces both light and heat, making it exothermic.
Why burning a candle is an exothermic reaction not endothermic?
The reaction releases heat and light to its surroundings, so it is exothermic.
Which of the following is endothermic a dry ice evaporating b a sparkler burning c the reaction that occurs in a chemical cold pack often used to ice athletic injuries?
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
Is burning alcohol an exothermic or endothermic process?
Exothermic
Is burning a match an endothermic or exothermic change?
Burning a match is an exothermic change because energy is being released.
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
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 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 burning petrol exothermic or endothermic?
Burning petrol is an exothermic process. It releases heat and light as energy is given off during the combustion of petrol.
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 burning octane exothermic or endothermic?
Burning octane is an exothermic reaction because it releases energy in the form of heat and light as it reacts with oxygen to form carbon dioxide and water.

Classify the burning of natural gasses in exothermic or endothermic changes?
The burning of natural gas is an exothermic process.
Is burning 2-propanol endothermic?
Any time you burn something, it's exothermic.
