Question

balance C2 H5 OH + O2 gives out CO2 + H2O​

Answer 1

Balanced equation:

C2H5OH + 3 O2 = 2 CO2 + 3 H2O

Answer 2

Answer:

C2H5OH + O2 = CO2 + H2O

C2H5OH + 3O2 = 2 CO2 + 3H2O

Explanation:

Since there is 2 in frount of carbon in LHS we put 2 behind CO2 in the RHS. Now there are 6 H and 3 O in LHS and 2 H and 4 O in RHS.

We now place 3 behind H2O in RHS to balance the no of hydrogen . Then there are 3 O in LHS and 7 O in RHS. Thus on placing 3 behind O2 we balance oxygen too.
