Question

Part 1.) Write a balanced chemical equation, including states of matter, for the combustion of gaseous benzene, C6H6.

Part 2.) Write a balanced chemical equation, including states of matter, for the combustion of ethylene gas, C2H4.

Answer 1

1)

C6H6 (g) + O2 (g) —> CO2 (g) + H2O (g)

Balance C:

C6H6 (g) + O2 (g) —> 6 CO2 (g) + H2O (g)

Balance H:

C6H6 (g) + O2 (g) —> 6 CO2 (g) + 3 H2O (g)

Balance O:

2 C6H6 (g) + 15 O2 (g) —> 12 CO2 (g) + 6 H2O (g)

This is answer

2)

C2H4 (g) + O2 (g) —> CO2 (g) + H2O (g)

Balance C:

C2H4 (g) + O2 (g) —> 2 CO2 (g) + H2O (g)

Balance H:

C2H4 (g) + O2 (g) —> 2 CO2 (g) + 2 H2O (g)

Balance O:

C2H4 (g) + 3 O2 (g) —> 2 CO2 (g) + 2 H2O (g)

This is answer
