Phosphine gas can also be made by reacting white phosphorus with water. The products are phosphine gas and phosphoric acid, H3PO4. Construct an equation for this reaction.

What are you thinking so far? Can you write out the formulae for each of the species involved?

Phosphine gas is PH3, P is phosphorus and water - as you may know - H2O. By balancing an equation, the number of atoms has to be both on left and right side of the chemical equation the same.

P4 + 3h2o -> 3ph3 + h3po4

:eek:

The chemical equation is not correct: you have six H-atoms on the left, but twelve of them on the right side! and three O-atoms on the left and four on the right side. It is not balanced.
