, how many grams of phosphoric acid will be formed upon the complete reaction of 32.8 grams of tetraphosphorus decaoxide with excess perchloric acid (HClO4)?

Question

kira_yamato · Answer

You need to first figure out the balanced equation between P4O12 and HClO4.

kira_yamato · Answer

This is a redox reaction.

joannablackwelder · Answer

Tetraphosphorous decaoxide is P4O10

kira_yamato · Answer

Oh thanks. So used to looking at chemical formula.
In that case, it's no longer a redox. It's just a double ion displacement sorta thing.
12HClO4 + P4O10 --> 4H3PO4 + 6Cl2O7

kira_yamato · Answer

Find the number of moles of P4O10 first, and you can multiply that by 4 to get the number of moles of H3PO4. This will then give you the mass of H3PO4 produced.
