Answer:

May be third one because of the formation of H2(hydrogen)on the product side.

The equation that shows the valued combustion reaction is [tex]C_2H_4 + 3O_2 \rightarrow 2CO_2 + 2H_2O[/tex]

The following information should be considered:

  • For [tex]2Al + 2O_2 \rightarrow 2AlO + O_2[/tex]  it should not Balanced Properly [tex]2Al + O_2 = 2AlO[/tex]
  • For [tex]2CH_4 + O_2 \rightarrow 2CO + 4H_2[/tex]   as CO should be [tex]CO_2[/tex]
  • For [tex]Ca + O_2 \rightarrow CaOH[/tex] it should Not Balanced and No source for the H.
