Reactions of Combustion with Coefficients

When a substance undergoes combustion, it reacts with oxygen to produce carbon dioxide and water. The coefficients in the reaction equation represent the number of molecules or moles of each substance involved in the reaction. Here are the reactions of combustion for different compounds with their respective coefficients:

1. CxH8 (Hydrocarbon): - The combustion reaction of a hydrocarbon with the formula CxH8 can be represented as: CxH8 + (x + 4)O2 → xCO2 + 4H2O [[1]]. - In this reaction, x represents the number of carbon atoms in the hydrocarbon.

2. CxHy (Hydrocarbon): - The combustion reaction of a hydrocarbon with the formula CxHy can be represented as: CxHy + (x + y/4)O2 → xCO2 + (y/2)H2O [[2]]. - In this reaction, x represents the number of carbon atoms, and y represents the number of hydrogen atoms in the hydrocarbon.

3. CnH2n (Alkene): - The combustion reaction of an alkene with the formula CnH2n can be represented as: CnH2n + (n + 1)O2 → nCO2 + nH2O [[3]]. - In this reaction, n represents the number of carbon atoms in the alkene.

4. CnH2n-2 (Alkyne): - The combustion reaction of an alkyne with the formula CnH2n-2 can be represented as: CnH2n-2 + (n + 1.5)O2 → nCO2 + (n-1)H2O [[4]]. - In this reaction, n represents the number of carbon atoms in the alkyne.

5. CxHyO (Alcohol): - The combustion reaction of an alcohol with the formula CxHyO can be represented as: CxHyO + (x + 0.5y)O2 → xCO2 + (y/2)H2O [[5]]. - In this reaction, x represents the number of carbon atoms, y represents the number of hydrogen atoms, and O represents the number of oxygen atoms in the alcohol.

6. CnH2n+2O (Aldehyde): - The combustion reaction of an aldehyde with the formula CnH2n+2O can be represented as: CnH2n+2O + (n + 1.5)O2 → nCO2 + (n+1)H2O [[6]]. - In this reaction, n represents the number of carbon atoms in the aldehyde.

7. CxHyOz (Organic Compound): - The combustion reaction of an organic compound with the formula CxHyOz can be represented as: CxHyOz + (x + 0.5y + 0.25z)O2 → xCO2 + (y/2)H2O + (0.5z)O2 [[7]]. - In this reaction, x represents the number of carbon atoms, y represents the number of hydrogen atoms, and z represents the number of oxygen atoms in the organic compound.

These reactions of combustion provide a general understanding of how different compounds react with oxygen to produce carbon dioxide and water. The coefficients in the reaction equations represent the stoichiometric ratios between the reactants and products.
