Which of the following is the correct name for the compound S3Cl2? Sulfur chloride Sulfur (III) chloride Sulfur (II) chloride Tr
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
The given formula has three sulfur atoms and two chlorine atoms.
is a covalent compound as it is formed by sharing of electrons.
So, according to the nomenclature rule "tri" will be added before the name of cation because there are three atoms of cation and "di" will be added before the name of anion.
Therefore, we can conclude that the correct name of compound is Trisulfur dichlroide.

Answer:
Kp = 1.41 x 10⁻⁶
Explanation:
We have the chemical equation:
2 A(g) + 3 B(g)⇌ C(g)
In which A and B are the reactants and C is the product. We calculate first the change in the number of moles of gas (Δn or dn):
dn= (sum moles products - sum moles reactants)
= (moles C - (moles A + moles B))
= (1 - (2+3))
= 1 - 5
= -4
We have also the following data:
Kc = 63.2
T= 81∘C + 273 = 354 K
R = 0.082 L.atm/K.mol (it is a constant)
Thus, we introduce the data in the mathematical expression for the relation between Kp and Kc:
= (0.082 L.atm/K.mol x 354 K)⁻⁴ = 1.41 x 10⁻⁶
