is it 1425

BOBSLAYER Here bob we've been over this just putting the question or an explanation of how easy the question is DOES NOT HELP. We're looking for A.B.C.or D an explanation on how and why.

The correct coefficients to balance the equation are: 2, 6, 1, 10.

The balanced equation is:

2 PCl5 + 6 H2O → H3PO4 + 10 HCl

To balance the given chemical equation, PCl5 + H2O → H3PO4 + HCl, we need to ensure that the same number of atoms are present on both sides of the equation.

Let's start by balancing the phosphorus (P) atoms.

On the left-hand side, there is only 1 P atom in PCl5, while on the right-hand side, there is 1 P atom in H3PO4. To balance this, place a coefficient of 1 in front of PCl5 and H3PO4.

Now, let's balance the chlorine (Cl) atoms.

On the left-hand side, there are 5 Cl atoms in PCl5, while on the right-hand side, there is 1 Cl atom in HCl. To balance this, place a coefficient of 5 in front of HCl.

Next, let's balance the hydrogen (H) atoms.

On the left-hand side, there are 2 H atoms in H2O, while on the right-hand side, there are 3 H atoms in H3PO4 and 1 H atom in HCl. To balance this, place a coefficient of 6 in front of H2O, 2 in front of H3PO4, and 2 in front of HCl.

Finally, let's balance the oxygen (O) atoms.

On the left-hand side, there are 1 O atom in H2O, while on the right-hand side, there are 4 O atoms in H3PO4. To balance this, place a coefficient of 4 in front of H2O.

The balanced equation is:
PCl5 + 6H2O → 2H3PO4 + 5HCl

So, the correct coefficients to balance the equation are 1, 6, 2, 5. Therefore, the correct option is 1, 6, 2, 5, not 1425.

PCl5 + 4H2O → H3PO4 + 5HCl
