Question

What are the correct coefficients (reading from left to right) when the chemical equation is balanced?

__PCl5(l)+__H2O(l)→__H3PO4(aq)+__HCl(aq)

Answer 1

The balanced chemical equation for PCl5(l) + H2O(l) → H3PO4(aq) + HCl(aq) has the coefficients 1, 4, 1, and 5, respectively.

Step-by-step explanation:

To balance the chemical equation provided, we must ensure that the number of atoms of each element on the reactant side is equal to the number of atoms of that element on the product side.

For the reaction PCl5(l) + H2O(l) → H3PO4(aq) + HCl(aq), the correct coefficients, reading from left to right, are 1, 4, 1, and 5, respectively. This gives us a balanced equation of 1PCl5(l) + 4H2O(l) → 1H3PO4(aq) + 5HCl(aq).

Answer 2

PCL5[l]+4H2O=H3PO4+5HCL
