Question

Which of the following shows a valid combustion reaction?

2Al + 2O2 → 2AlO + O2
C2H4 + 3O2 → 2CO2 + 2H2O
2CH4 + O2 → 2CO + 4H2
Ca + O2 → CaOH

Answer 1

Combustion reaction means two common products

1. CO_2
2. H_2O

Option B is correct

$\\ \sf\longmapsto C_2H_4+O_2\longrightarrow 2CO_2+2H_2O$
