The coefficients needed to balance the equation would be 2, 7, 4, and 6 respectively.
<h3>Balancing chemical equation</h3>
This requires that the number of atoms of each element is the same both on the reactant and product's sides.
Hence, the balanced equation of the reaction becomes:

Thus, the coefficient for each species would be 2, 7, 4, and 6 respectively.
