When the following redox equation is balanced with smallest whole number coefficients, the coefficient for nitrogen dioxide will
Phoenix [80]

In a redox reaction, electron could be lost or gained. The coefficients in the balanced redox reaction are;  1/2, 5, 1, 5, 2, 1.

<h3>What is a redox reaction equation?</h3>

A redox reaction equation shows the species that were oxidized or reduced in a redox reaction. In this case, we are asked for the coefficients in a balanced redox reaction equation.

We must recall that five electrons were lost/gained in the process hence the balanced reaction equation is;

1/2I2 + 5HNO3 -----> IO3^- + 5NO2 + 2H2O + H^+

The coefficients in the balanced equation therefore are; 1/2, 5, 1, 5, 2, 1.
