Answer:

What Do Nails Do? Nails protect the sensitive tips of fingers and toes. We don't need our nails to survive, but they do support the tips of our fingers and toes, protect them from injury, and help us pick up small objects.

Ammonium phosphate ((NH4)3PO4) is an important ingredient in many fertilizers. It can be made by reacting phosphoric acid (H3PO4

Alex Ar [27]

Taking into account the reaction stoichiometry, 8.8488 grams of (NH₄)₃PO₄ is produced by the reaction of 5.82g of phosphoric acid.

<h3>Reaction stoichiometry</h3>

In first place, the balanced reaction is:

H₃PO₄ + 3 NH₃ → (NH₄)₃PO₄

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

H₃PO₄: 1 mole
NH₃: 3 moles
(NH₄)₃PO₄: 1 mole

The molar mass of the compounds is:

H₃PO₄: 98 g/mole
NH₃: 17 g/mole
(NH₄)₃PO₄: 149 g/mole

Then, by reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

H₃PO₄: 1 mole ×98 g/mole= 98 grams
NH₃: 3 moles ×17 g/mole= 51 grams
(NH₄)₃PO₄: 1 mole ×149 g/mole= 149 grams

<h3>Mass of ammonium phosphate formed</h3>

The following rule of three can be applied: if by reaction stoichiometry 98 grams of H₃PO₄ form 149 grams of (NH₄)₃PO₄, 5.82 grams of H₃PO₄ form how much mass of (NH₄)₃PO₄?

mass of (NH₄)₃PO₄= $\frac{5.82 grams of H_{3} PO_{4}x149 grams of (NH_{4} )_{3}PO_{4} }{98 grams of H_{3} PO_{4}}$

<u><em>mass of (NH₄)₃PO₄= 8.8488 grams</em></u>

Finally, 8.8488 grams of (NH₄)₃PO₄ is produced by the reaction of 5.82g of phosphoric acid.
