    Answer:

    H3PO4 + 5 HCl → PCl5 + 4 H2O

    Explanation:

    The given equation is

    H3PO4 + HCl = PCl5 + H2O

    The above chemical equation has one P atom on both the sides, hence phosphorus is balanced

    There are 5 Cl on the RHS but only one Cl on the LHS. On balancing the chlorine, we get –

    H3PO4 + 5HCl = PCl5 + H2O

    Now, there are 8 hydrogen atom on the LHS but only two on the RHS. On balancing the hydrogen on both the sides, the new equation become

    H3PO4 + 5HCl = PCl5 + 4H2O

    Let us check for oxygen

    Oxygen on LHS = 4 and oxygen on RHS = 4

    Thus, the balanced equation is H3PO4 + 5HCl = PCl5 + 4H2O
