Coefficients in the Chemical Equation

The coefficients in a chemical equation represent the number of moles of each substance involved in the reaction. In the given equation C2H4 + O2 → CO2 + H2O, the coefficients are as follows:

- C2H4: 1 - O2: 3 - CO2: 2 - H2O: 2

These coefficients are used to balance the chemical equation, ensuring that the same number of atoms of each element are present on both sides of the equation.

The balanced equation is: C2H4 + 3O2 → 2CO2 + 2H2O.

This balanced equation indicates that 1 mole of C2H4 reacts with 3 moles of O2 to produce 2 moles of CO2 and 2 moles of H2O
