Is a combustion reaction an endothermic reaction?
No, a combustion reaction is typically exothermic because it releases heat energy. Endothermic reactions absorb heat energy from the surroundings.
Is cracking hydrocarbon molecules an endothermic or exothermic reaction?
Cracking hydrocarbon molecules is an endothermic reaction. This process requires energy input to break the chemical bonds in larger hydrocarbon molecules, resulting in smaller molecules, such as alkanes and alkenes. The energy absorbed during cracking exceeds the energy released from the formation of the new bonds in the products, making it endothermic.
What type of combustion fuels produces carbon dioxide?
Combustion fuels that produce carbon dioxide typically include fossil fuels such as coal, oil, and natural gas. When these fuels are burned, they react with oxygen to release energy, resulting in the byproduct of carbon dioxide (CO2) along with water vapor. Biomass fuels, like wood and agricultural waste, also emit CO2 when combusted. Overall, any hydrocarbon-based fuel, when burned, contributes to CO2 emissions.
What wold be produced in a combustion reaction?
After combustion water and carbon dioxide are released.
What reactions form a combustion reaction?
A hydrocarbon and oxygen
What is the equation for complete combustion of fossil fuels?
The general equation for the complete combustion of a hydrocarbon fuel such as fossil fuels is: hydrocarbon + oxygen → carbon dioxide + water For example, the complete combustion of methane (CH4) would be: CH4 + 2O2 → CO2 + 2H2O.
What determines whether hydrocarbon fuels undergo complete or incomplete combustion?
if it is on fire or in a pool with lots of fish eating marshmellows
Why is it usually difficult to burn different hydrocarbon fuels efficiently in the same appliance?
It is difficult to burn different hydrocarbon fuels efficiently in the same appliance because different fuels have varying compositions, burning temperatures, and combustion characteristics. This can make it challenging to optimize combustion conditions, such as air-to-fuel ratios and flame stability, to achieve efficient and complete combustion across multiple fuel types.
How do the combustion of some impurities in hydrocarbon fuels result in the formation of sulfur dioxide?
When hydrocarbon fuels containing sulfur impurities are burned, the sulfur combines with oxygen in the air to form sulfur dioxide (SO2) during combustion. This process occurs because sulfur is an element present in some fuels, and when it reacts with oxygen from the air at high temperatures, it forms sulfur dioxide gas.
What are the products of combustion of a hydrocarbon?
The complete combustion of a hydrocarbon would give carbon dioxide and water as the only products.
The product of combustion of a hydrocarbon are?
The complete combustion of a hydrocarbon would give carbon dioxide and water as the only products.
What is the chemical equation for complete combustion of a hydrocarbon?
The general chemical equation for the complete combustion of a hydrocarbon is: Hydrocarbon + O2 -> CO2 + H2O For example, the combustion of methane (CH4) can be represented as: CH4 + 2O2 -> CO2 + 2H2O
Why do modern cars burn hydrocarbon fuels in their engines?
Hydrocarbon fuels are energy dense, easily transported, relatively cheap.
Why do most modern cars burn hydrocarbon fuels in their engines?
Hydrocarbon fuels are energy dense, easily transported, relatively cheap.
Is combustion exothermic or endothermic?
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
Is a combustion reaction an endothermic reaction?
No, a combustion reaction is typically exothermic because it releases heat energy. Endothermic reactions absorb heat energy from the surroundings.
What are everyday uses of exothermic and endothermic?
EXOTHERMIC: any combustion ENDOTHERMIC: evaporation of liquids
