How many grams of carbon dioxide is produced from the combustion of B grams of hexane?
The combustion of hexane (C6H14) produces carbon dioxide (CO2) according to the reaction: C6H14 + 7O2 → 6CO2 + 7H2O. For every 1 gram of hexane burned, approximately 3.03 grams of carbon dioxide are produced. Therefore, from the combustion of B grams of hexane, the amount of carbon dioxide produced would be approximately 3.03B grams.
Is formation of hexane exothermic?
Yes, the formation of hexane is an exothermic process. When hexane (C6H14) is synthesized, typically from smaller hydrocarbons or through reactions like hydrogenation of alkenes, energy is released as new bonds are formed. This release of energy during bond formation indicates that the overall process is exothermic.
In what processes are energy released?
condensation A+ : )
Is energy a reactant or product of the combustion reaction?
Energy is typically released as a product in a combustion reaction. The reaction releases energy in the form of heat as the fuel combusts with oxygen to form products such as carbon dioxide and water.
Is heat of combustion a chemical property of matter?
Yes, heat of combustion is a chemical property of matter. It refers to the energy released when a substance undergoes complete combustion with oxygen. It is specific to each substance and can be used to determine the energy content of fuels.
If hexane was burned in a limited supply of oxygen the combustion would not be complete?
This depends on how much hexane was being burned and how much oxygen was present.Because the complete combustion of carbon involves placing two moles of oxygen on one mole of carbon plus the formation of water, you would need 19 moles of diatomic oxygen for every one mole of hexane.1 C6H14 + 19 O2 --> 6 CO2 + 7 H2O
What is the word equation for burning petrol in an engine?
Hexane + Oxygen -> Carbon Dioxide + Water - for full combustion Hexane + Oxygen -> Carbon + Carbon Monoxide + Water - for partial combustion
How many grams of carbon dioxide is produced from the combustion of B grams of hexane?

For every 1 gram of hexane burned, approximately 3.03 grams of carbon dioxide are produced. Therefore, from the combustion of B grams of hexane, the amount of carbon dioxide produced would be approximately 3.03B grams.
What is usually released in a combustion reaction?
energy
Why is combustion exothermic reaction?
because during combustion heat energy is released. for example the burning of carbon in air is a combustion reaction but in this process 393.7 K.J/mol energy is released
Why are hexane used fuels?
Hexane C6H14 is one of the alkane family of fuels starting with methane and butane. It is slightly lighter than gasoline and boils at a relatively low temperature so it is not used in vehicles.
Is burning wood an example of an exergonic or endergonic reaction?
Yes, combustion is an example of an exergonic reaction. During combustion, energy is released- making it an exergonic reaction.
Is Combustion is an example of an exergonic reaction.?
Yes, combustion is an example of an exergonic reaction. During combustion, energy is released- making it an exergonic reaction.
Is the energy input obtained from the energy released by the combustion of a fuel with air in the practical heat engine cycle?
Yes, in a practical heat engine cycle, the energy input is obtained from the energy released by the combustion of a fuel with air. This combustion process creates high-temperature gases that expand and drive the engine, converting the thermal energy into mechanical work.
What is the significance of combustion enthalpy in determining the energy released during a chemical reaction?
The combustion enthalpy is important because it measures the amount of energy released when a substance undergoes combustion. This value helps determine the overall energy released during a chemical reaction, which is crucial for understanding the reaction's efficiency and potential impact on the surroundings.
What mass of carbon dioxide is produced by the complete combustion of 5.50 grams of hexane?
The chemical formula of hexane is C6H14. To find the mass of CO2 produced, first calculate the molar mass of hexane. Then use stoichiometry to find the molar ratio between hexane and CO2. Finally, calculate the mass of CO2 produced using this ratio and the given mass of hexane.
Why combustion of hexane produce no soot?
Combustion of hexane produces no soot because it is a clean-burning hydrocarbon with a simple molecular structure. When hexane combusts, it forms carbon dioxide and water vapor as the main products, without leaving behind carbon particles that would create soot.
