Answer 2

Reactions of Combustion of Complex Substances:

a) C2H4 + O2 → 2CO2 + 2H2O: - The reaction between ethene (C2H4) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[1]].

b) C2H6 + O2 → 2CO2 + 3H2O: - The reaction between ethane (C2H6) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[2]].

в) C3H6 + O2 → 3CO2 + 3H2O: - The reaction between propene (C3H6) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[3]].

г) C3H4 + O2 → 3CO2 + 2H2O: - The reaction between propyne (C3H4) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[4]].

д) C3H8 + O2 → 3CO2 + 4H2O: - The reaction between propane (C3H8) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[5]].

е) C4H8 + O2 → 4CO2 + 4H2O: - The reaction between butene (C4H8) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[6]].

ж) C5H12 + O2 → 5CO2 + 6H2O: - The reaction between pentane (C5H12) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[7]].

з) C6H6 + O2 → 6CO2 + 3H2O: - The reaction between benzene (C6H6) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[8]].

и) C7H8 + O2 → 7CO2 + 4H2O: - The reaction between toluene (C7H8) and oxygen (O2) produces carbon dioxide (CO2) and water (H2O) as the main products [[9]].

Please note that these reactions represent the combustion of the given substances in the presence of oxygen. The products mentioned are the main products formed during the combustion process.
