Problem 149 Hard Difficulty

Phosphoric acid $\left(\mathrm{H}_{3} \mathrm{PO}_{4}\right)$ is an important industrial chemical used in fertilizers, in detergents, and in the food industry. It is produced by two different methods. In the electric furnace method, elemental phosphorus $\left(P_{4}\right)$ is burned in air to form $\mathrm{P}_{4} \mathrm{O}_{10},$ which is then reacted with water to give $\mathrm{H}_{3} \mathrm{PO}_{4}$. In the wet process, the mineral phosphate rock fluorapatite $\left[\mathrm{Ca}_{5}\left(\mathrm{PO}_{4}\right)_{3} \mathrm{F}\right]$ is reacted with sulfuric acid to give $\mathrm{H}_{3} \mathrm{PO}_{4}$ (and HF and $\mathrm{CaSO}_{4}$ ). Write equations for these processes and classify each step as precipitation, acid-base, or redox reaction.

Okay. Question one for the night off. Deny. Well, buddy ny one for night. So, ace the electric for nice metal we have for for s for here. Less fire. Oxygen gas produced before all 10. And now we're going to notice Aussie Productive. Russian or not, we have to find the oxidation number and receive a leichtman free and four for free elements. Also p zero here. Oxygen free Airman's off zero here. And for for us in this camp. Out for rest back plus five and oxygen minus two. Therefore, this is readapt Russian. And this we lost fourth before all 10 react with water to fall for for it as it Missy she Then I sit here to look for here. Okay, now. But this when you see this either combination reaction before all turn here I sit outside, but it is no wrong past as it because it cannot Don't know hydrogen. So this in the acid and base direction. But it is already note Alcide. I said it outside because when they dissolve water they agreed the 100 brought up concentration. But we cannot say duck as it and Ajax and only combination direction and be see if I be awful. Three If so, this will be three night three. So five by here too we see cost himself a precipitate. So this P ray c B day reaction, okay?
