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.

How many moles of K+ and PO4^3- ions are present in 20.0 mL of a 0.015 M solution of potassium phosphate?

Romashka-Z-Leto [24]

Answer:

$n_{K^+}=0.0009molK^+$

Explanation:

Hello,

In this case, the first step is to compute the number of moles of potassium phosphate in 20.0 mL (0.020L) of the 0.015-M (mol/L) solution as shown below:

$n=0.020L*0.015\frac{mol}{L}=0.0003mol$

Thus, these moles correspond to potassium phosphate moles, which molecular formula is K₃PO₄, therefore, one mole of this compound contains three moles of potassium ions as it has three as its subscript in the formula. Thereby, the moles of potassium ions result in:

$n_{K^+}=0.0003molK_3PO_4*\frac{3molK^+}{1molK_3PO_4} \\\\n_{K^+}=0.0009molK^+$

Best regards.

Why does a mixture of hydrogen and oxygen in a balloon not spontaneously explode at room temperature

Tom [10]

Answer:

Because the molecules of the mixture would be compact or bond together at room temperature. In this case, both gases will condense to form water (or ice, if the room temperature is prolonged) and such droplets of water will not cause a balloon to spontaneously explode at room temperature.

Explanation:

A mixture of hydrogen and oxygen will form water. Recall that the chemical formula for water is H₂O, where H represents Hydrogen and O represents Oxygen.

A balloon is a light (not thick) solid substance with a thin membrane when blown or filled with some elements or gases.

Room Temperature means cool or cold temperature. You already know that generally at room temperature, the molecules of any substance will stick together or will become less mobile (less spontaneous).

In this case, hydrogen gas and oxygen gas will go through a process called condensation - to form water - and then through the process called freezing - to form ice.

At room temperature, the gases will first change state (state of matter) from gaseous to liquid and then from liquid to solid.

This is why the balloon will NOT spontaneously explode.
