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.

The number of valence electrons in will be 26.
The atom's outermost inhabited shell is where valence electrons are found. They are significant because they have a major impact on how an atom's chemical characteristics are determined.
The number of valence electron in P in 5 and number of valence electron in Cl is 7. There are one molecule of P and three molecule of Cl in molecule. By adding all valence electrons , the total number of valance electrons will be 26.
The Lewis structure of is shown as:
Therefore, the number of valence electrons in will be 26.
