N2<span> + 3H</span>2<span> = 2NH</span><span>3
so, NH3 = (N2 + 3H2)/ 2
= (28g + 3*25g)/2
= 51.5g</span>
Answer:
Part A
K = (K₂)²
K = (K₃)⁻²
Part B
K = √(Ka/Kb)
Explanation:
Part A
The parent reaction is
2Al(s) + 3Br₂(l) ⇌ 2AlBr₃(s)
The equilibrium constant is given as
K = [AlBr₃]²/[Al]²[Br₂]³
2) Al(s) + (3/2) Br₂(l) ⇌ AlBr₃(s)
K₂ = [AlBr₃]/[Al][Br₂]¹•⁵
It is evident that
K = (K₂)²
3) AlBr₃(s) ⇌ Al(s) + 3/2 Br₂(l)
K₃ = [Al][Br₂]¹•⁵/[AlBr₃]
K = (K₃)⁻²
Part B
Parent reaction
S(s) + O₂(g) ⇌ SO₂(g)
K = [SO₂]/[S][O₂]
a) 2S(s) + 3O₂(g) ⇌ 2SO₃(g)
Ka = [SO₃]²/[S]²[O₂]³
[SO₃]² = Ka × [S]²[O₂]³
b) 2SO₂(g) + O₂(g) ⇌ 2 SO₃(g)
Kb = [SO₃]²/[SO₂]²[O₂]
[SO₃]² = Kb × [SO₂]²[O₂]
[SO₃]² = [SO₃]²
Hence,
Ka × [S]²[O₂]³ = Kb × [SO₂]²[O₂]
(Ka/Kb) = [SO₂]²[O₂]/[S]²[O₂]³
(Ka/Kb) = [SO₂]²/[S]²[O₂]²
(Ka/Kb) = {[SO₂]/[S][O₂]}²
Recall
K = [SO₂]/[S][O₂]
Hence,
(Ka/Kb) = K²
K = √(Ka/Kb)
Hope this Helps!!!

The boiling point is the temperature at region 4
Explanation:
Answer:
<h3>Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.</h3>
Answer:
Greater the mass
Greater kinetic energy
Velocity
Greater kinetic energy
Mass and velocity
Explanation:
We know that kinetic energy of object
Where m=Mass of object
v=Velocity of object
Kinetic energy is directly proportional to mass and velocity of object.
When mass of object is greater then the object has greater kinetic energy when the mass of object is small then the object has small kinetic energy.
When the velocity of object is greater then the object has greater kinetic energy when the velocity of object is small then the object has small kinetic energy.
The greater the mass of an object moves,the greater the kinetic energy it has.
The greater the velocity of a moving object,the greater kinetic energy it has.
Kinetic energy depends on both mass and velocity of object.
