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.
Answer:
6
Explanation:
Carbon is the 6th element of the periodic table and the atomic number is the same as the amount of electrons it has.
2C + O2 = 2CO is balanced.
If you look you can see the first side has 2 Cs and 2 Os, and the other side has the same amount, just put together making both sides even and balanced.
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.
Answer:
I think the answer is 6.022*10^23
