a. 30 moles of H₂O
b. 2.33 moles of N₂
<h3>Further explanation</h3>
Given
a. 20 moles of NH₃
b. 3.5 moles of O₂
Required
a. moles of H₂O
b. moles of N₂
Solution
Reaction
4NH₃+3O₂⇒2N₂+6H₂O
a. From the equation, mol ratio NH₃ : H₂O = 4 : 6, so mol H₂O :
=6/4 x mol NH₃
= 6/4 x 20 moles
= 30 moles
b. From the equation, mol ratio N₂ : O₂ = 2 : 3, so mol N₂ :
=2/3 x mol O₂
= 2/3 x 3.5 moles
= 2.33 moles

I think so, sorry if its wrong.
The structure of Ionic bonds affects the structure of ionic compounds in many ways including Melting point, boiling point, form in room temp, stress of molecules and many other things.
Answer:
E = 3.825×10⁻¹⁹ J
Explanation:
Wavelength of photon = 5.2 ×10⁻⁷m
Energy of photon = ?
Solution:
Formula:
E = hc/λ
h = plancks constant = 6.63×10⁻³⁴ Js
c = speed of wave = 3×10⁸ m/s
by putting values,
E = 6.63×10⁻³⁴ Js ×3×10⁸ m/s / 5.2 ×10⁻⁷m
E = 19.89×10⁻²⁶ J.m / 5.2 ×10⁻⁷m
E = 3.825×10⁻¹⁹ J
Answer:
132 g/mol
Explanation:
(NH₄)₂SO₄ has 2 nitrogen atoms, 8 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.
From the periodic table, the molar mass of each element is:
N: 14.0 g/mol
H: 1.01 g/mol
S: 32.1 g/mol
O: 16.0 g/mol
So the molar mass of the compound is:
2N × (14.0 g/mol N) + 8H × (1.01 g/mol H) + 1S × (32.1 g/mol S) + 4O × (16.0 g/mol O)
= 28.0 + 8.08 + 32.1 + 64.0 g/mol
= 132 g/mol
If you need more precision, use more significant figures for the element molar masses.
