The coefficient of oxygen gas (O2) in the following balanced equation is: 4Na + O2 → 2Na2O, is 1.

BALANCING EQUATION:

  • A balanced equation is an equation that contains the same number of atoms of each element on both sides of the equation.

  • Balancing a chemical reaction requires the use of coefficients, which are numbers placed in front of the elements/compounds involved.

  • According to this question, the following reaction is given:

  • Na + O2 → Na2O

  • The balanced chemical equation using coefficients is as follows:

  • 4Na + O2 → 2Na2O

  • This balanced equation shows that 1 mole of oxygen is involved, hence, the coefficient is 1.
