Ah, the coefficient for O2 is a number placed in front of the oxygen molecule in a chemical equation. It shows how many molecules of O2 are involved in the reaction. Remember, each element has its own coefficient to balance the equation and show the right proportions of each molecule. Just like adding a touch of color to a painting, coefficients help balance the equation beautifully.
The coefficient of O2 is 5.The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
C3H8 + 5O2 = 3CO2 + 4H2O, so the coefficient for O2 is 5
2H2O2------------ 2 H2O + O2 thus correct coefficient is 2
The balanced equation for the reaction of potassium with oxygen is: 4K + O2 -> 2K2O The coefficient of oxygen in this balanced equation is 1.
The coefficient of oxygen in the reaction P + O2 → P2O3 is 1. This means that one molecule of oxygen (O2) reacts with one molecule of phosphorus (P) to form one molecule of phosphorus oxide (P2O3).

The coefficient for water in the balanced equation is 6.
To balance the equation C6H14 + O2 -> CO2 + H2O, start by balancing the carbon atoms. This requires putting a coefficient of 6 in front of CO2. Next, balance the hydrogen atoms by adding a coefficient of 7 in front of H2O. Finally, balance the oxygen atoms by adjusting the coefficient in front of O2, which in this case is 9.
In the balanced chemical equation 4Fe + 3O2 -> 2Fe2O3, the coefficient in front of iron (Fe) is 4.
