C2H5OH(l) + O2(g) ? 2CO2(g) + 3H2O(g)                 C. C2H5OH(l) + 3O2(g) ? 2CO2(g) + 3H2O(g)                 D. 2C2H5OH(l) + 3O2(g) ? 4CO2(g) + 3H2O(g)                 E. C2H5OH(l) + O2(g) ? CO2(g) + 3H2O(g) Balance the following skeletal equation:  C2H5OH(l) + O2(g) ? CO2(g) + H2O(g). C2H5OH(l) + 2O2(g) ? 2CO2(g) + 3H2O(g) C2H5OH(l) + O2(g) ? 2CO2(g) + 3H2O(g) C2H5OH(l) + 3O2(g) ? 2CO2(g) + 3H2O(g) 2C2H5OH(l) + 3O2(g) ? 4CO2(g) + 3H2O(g) C2H5OH(l) + O2(g) ? CO2(g) + 3H2O(g)                 A. C2H5OH(l) + 2O2(g) ? 2CO2(g) + 3H2O(g)                 B. C2H5OH(l) + O2(g) ? 2CO2(g) + 3H2O(g)                 C. C2H5OH(l) + 3O2(g) ? 2CO2(g) + 3H2O(g)                 D. 2C2H5OH(l) + 3O2(g) ? 4CO2(g) + 3H2O(g)                 E. C2H5OH(l) + O2(g) ? CO2(g) + 3H2O(g)

Explanation / Answer

Burning alcohol
First
1 C2H5OH + O2 -> 2 CO2 + 3 H2O to balance the just the carbons and hydrogens
now count the oxygens in the products 4+3=7
and determine the number of oxygens:

1 C2H5OH +3 O2 -> 2 CO2 + 3 H2O
