Equations for the Combustion of Complex Substances

1. Hydrogen sulfide (H2S): - The equation for the combustion of hydrogen sulfide is: ``` 2H2S + 3O2 -> 2H2O + 2SO2 ``` - This equation shows that when hydrogen sulfide reacts with oxygen, it produces water and sulfur dioxide [[1]].

2. Methane (CH4): - The equation for the combustion of methane is: ``` CH4 + 2O2 -> CO2 + 2H2O ``` - This equation represents the reaction of methane with oxygen to produce carbon dioxide and water [[2]].

3. Zinc sulfide (ZnS): - Zinc sulfide does not undergo combustion as it is not a hydrocarbon. Instead, it can undergo other types of reactions, such as oxidation or reduction.

4. Carbon disulfide (CS2): - The equation for the combustion of carbon disulfide is: ``` CS2 + 3O2 -> CO2 + 2SO2 ``` - This equation shows that when carbon disulfide reacts with oxygen, it produces carbon dioxide and sulfur dioxide [[3]].

5. Glucose (C6H12O6): - The equation for the combustion of glucose is: ``` C6H12O6 + 6O2 -> 6CO2 + 6H2O ``` - This equation represents the reaction of glucose with oxygen to produce carbon dioxide and water [[4]].

6. Acetylene (C2H2): - The equation for the combustion of acetylene is: ``` 2C2H2 + 5O2 -> 4CO2 + 2H2O ``` - This equation shows that when acetylene reacts with oxygen, it produces carbon dioxide and water [[5]].

7. Phosphine (PH3): - The equation for the combustion of phosphine is: ``` 4PH3 + 8O2 -> P4O10 + 6H2O ``` - This equation represents the reaction of phosphine with oxygen to produce phosphorus pentoxide and water [[6]].

Please note that these equations represent the combustion reactions of the given substances. Other reactions, such as oxidation or reduction, may also occur depending on the specific conditions and reactants involved.
