Chemical reaction: PCl₅ → PCl₃ + Cl₂.
n(PCl₅) = 0,366 mol.
V(PCl₅) = 4,45 L.
c(PCl₅) = n(PCl₅) ÷ V(PCl₅).
c(PCl₅) = 0,366 mol ÷ 4,45 L.
c(PCl₅) = 0,082 mol/L.
Kc = 1,80.
[PCl₃] = [Cl₂] = x.
Kc = [PCl₃] · [Cl₂] ÷ [PCl₅].
1,80 = x² ÷ (0,082 mol/L - x).
Solve quadratic eqaution: x = [PCl₃] = 0,078 mol/L.
[PCl₅] = 0,082 mol/L - 0,078 mol/L.
[PCl₅] = 0,004 mol/L.
Answer: Option (c) is the correct answer.
Explanation:
A monomial is defined as an algebraic expression in which there is only one term present.
For example, 3x is a monomial.
A binomial is defined as an expression where there will be two terms present. For example, 
is a binomial.
A polynomial is defined as an algebraic expression which contains more than two terms.
For example, 
is a polynomial.
Thus, we can conclude that the given expression is a polynomial.
Answer:
V=25.133 cm^3
(Is 4 the diameter you were given? To get one of those answers, I think you May have put the wrong diameter)
Explanation:
Radius is diameter/2
R=4/2
R=2
Volume of a sphere=4/3πr3
V=4/3π(2)3
V=25.133 cm^3
<h3>Answer:</h3>
Molecular Formula = S₂O₂ (Disulfur Dioxide)
<h3>Solution:</h3>
Molecular formula is calculated by using following formula,
Molecular Formula = n × Empirical Formula ---- (1)
Also, n is given as,
n = Molecular Weight / Empirical Formula Weight
Molecular Weight = 96.13 g.mol⁻¹
Empirical Formula Weight = 32.06 (S) + 16.0 (O) = 48.06 g.mol⁻¹
So,
n = 96.13 g.mol⁻¹ ÷ 48.06 g.mol⁻¹
n = 2.0002 ≈ 2
Putting Empirical Formula and value of "n" in equation 1,
Molecular Formula = 2 × SO
Molecular Formula = S₂O₂ (Disulfur Dioxide)
