Draw the lewis structure for the polyatomic trisulfide s−23 anion. be sure to include all resonance structures that satisfy the
mezya [45]

The following are the steps involved in drawing Lewis structure of the polyatomic trisulfide anion S_{3}^{2-}:

Total number of valence electrons = (3 * 6) + 2 = 20 electrons

Resonance is not possible in this ion. The molecular geometry of the ion will be bent as there are two lone pairs and two bond pairs on the central atom.

Predict the geometry around the central atom in SO2- A) trigonal pyramidal B) tetrahedral C) octahedral D) trigonal planar E) tr
liubo4ka [24]

<u>Answer:</u> The correct answer is Option D.

<u>Explanation:</u>

To calculate the hybridization of SO_2, we use the equation:

\text{Number of electron pair}=\frac{1}{2}[V+N-C+A]

where,

V = number of valence electrons present in central atom  (S) = 6

N = number of monovalent atoms bonded to central atom  = 0

C = charge of cation  = 0

A = charge of anion = 0

Putting values in above equation, we get:

\text{Number of electron pair}=\frac{1}{2}[6]=3

The number of electron pair around the central metal atom are 3. This means that the hybridization will be sp^2 and the electronic geometry of the molecule will be trigonal planar.

Hence, the correct answer is Option D.

Find and fix each mistake in the following equilibrium constant expressions.
IRINA_888 [86]

Answer:

A. c. Keq=[H2]^2[S2]/[H2S]^2

B. b. Keq=[COCl2]/[CO][Cl2]

Explanation:

Hello,

In this case, considering the law of mass action which states that the equilibrium expression is written in terms of the concentration of products divided by the concentration of reactants considering the stoichiometric coefficients as powers we obtain:

A. For the reaction:

2H_2S(g)\rightleftharpoons 2H_2(g)+S_2(g)

The equilibrium expression is:

Keq=\frac{[H_2]^2[S_2]}{[H_2S]^2}

Therefore, answer is c. Keq=[H2]^2[S2]/[H2S]^2.

B. For the reaction:

CO(g)+Cl_2(g)\rightleftharpoons COCl_2(g)

The equilibrium expression is:

Keq=\frac{[COCl_2]}{[CO][Cl_2]}

Therefore, answer is b. Keq=[COCl2]/[CO][Cl2].

Regards.
