Combustion is a chemical reaction where a fuel combines with oxygen to release energy in the form of heat and light. The fuel molecules break apart and react with oxygen molecules to form new molecules, releasing energy in the process. This process is exothermic, meaning it releases more energy than it consumes.
What else can I help you with?
Is supporting combustion a chemical property?
is supports combustion is a chemical properties
What is the chemical equation (including phases) that describes the combustion of butene (C4H8)?
The chemical equation for the combustion of butene (C4H8) is: C4H8 6O2 - 4CO2 4H2O This equation shows that butene reacts with oxygen to produce carbon dioxide and water.
What is the property that describes how easily a substance catches fire and burn?
The property that describes how easily a substance catches fire and burns is called flammability. It measures the ability of a material to ignite and sustain combustion when exposed to a heat source.
What best describes the total mass of substances before and after a combustion reaction?
The total mass of substances before and after a combustion reaction remains the same, according to the law of conservation of mass. This means that the mass of the reactants is equal to the mass of the products formed during the reaction.
The change in internal energy for the combustion of 1.0 of octane at a pressure of 1.0 is 5084.1 If the change in enthalpy is 5074.3 how much work is done during the combustion?
The work done during the combustion process can be calculated using the equation: ΔH = ΔU + PΔV. Since the process is done at a constant pressure, the work done is equal to the change in enthalpy minus the change in internal energy: W = ΔH - ΔU = 5074.3 - 5084.1 = -9.8 J. Therefore, 9.8 J of work is done during the combustion.
