Tetraphosphorous decoxice (P4O10) reacts with water to produce phosphoric acid.

1. Write the balanced equation for this reaction. Do not include states of matter in the equation.

2) Determine the number of moles of P4O10 required to produce 5.00 moles of phosphoric acid.

3) Determine the number of moles of water required to produce 5.00 moles of phosphoric acid

1) P4O10 + 6H20 → 4H3PO4

2) 1.25 moles of P4O10

3) 7.5 moles of water

Explanation:

1. Write the balanced equation for this reaction

P4O10 + 6H20 → 4H3PO4

2) Determine the number of moles of P4O10 required to produce 5.00 moles of phosphoric acid.

For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4

If we get 5.00 moles of H3PO4, we'll have 5/4 = 1.25 moles of P4O10 consumed.

3) Determine the number of moles of water required to produce 5.00 moles of phosphoric acid

For 1 mole P4O10 consumed, we need 6 moles of water to produce 4 moles of H3PO4

If we have 5.00 moles of H3PO4, we'll get (6/4) * 5 = 7.5 moles of water consumed.
