Answer 2

Balancing Equations:

To balance the equation for the reaction between C2H5OH and O2, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's how we can balance it:

C2H5OH + O2 -> CO2 + H2O

To balance the equation, we start by counting the number of atoms for each element on both sides of the equation:

Carbon (C): - Left side: 2 - Right side: 1

Hydrogen (H): - Left side: 6 - Right side: 2

Oxygen (O): - Left side: 1 (from C2H5OH) + 2 (from O2) = 3 - Right side: 2 (from CO2) + 1 (from H2O) = 3

To balance the equation, we can start by balancing the carbon atoms:

C2H5OH + O2 -> 2CO2 + H2O

Next, we balance the hydrogen atoms:

C2H5OH + O2 -> 2CO2 + 3H2O

Finally, we balance the oxygen atoms:

C2H5OH + 3O2 -> 2CO2 + 3H2O

Therefore, the balanced equation for the reaction between C2H5OH and O2 is:

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