Ede4ka [16]

Answer:

18 mol  

Step-by-step explanation:

Step 1. Balanced equation

4NH₃ + 5O₂ ⟶ 4NO + 6H₂O

Step 2. Calculation:

You want to convert moles of NH₃ to moles of H₂O

The molar ratio is 6 mol H₂O:4 mol NH₃

Moles of H₂O = 12 mol NH₃ × (6 mol H₂O/4 mol NH₃)

Moles of H₂O = 18 mol H₂O

The reaction will form 18 mol of H₂O.

Ammonium (NH4+), carbonate (CO32−), and phosphate (PO43−) are all examples of: (a) multivalent metals (b) polyatomic ions (c) co
PtichkaEL [24]

Answer:

Option b) polyatomic ions

Explanation:

Polyatomic ions are ions consisting of two or more atoms.

From the question given above, we can see that each ions consist of more than one atom as shown below:

Ions >>>>>> Number of atom present

NH4+ >>>>> 2

CO32− >>>> 2

PO43− >>>> 2

Thus, we can say that the above ions are polyatomic ions.
