Predict the shape of the molecule.
GuDViN [60]

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

2

1

[V+N−C+A]

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

SbCl_5SbCl

5

:

In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.

The number of electron pairs are 5 that means the hybridization will be sp^3dsp

3

B and geometry of the molecule will be trigonal bipyramidal.

Consider the reaction below 2SO2(g) + O2(g) ⇌ 2SO3(g) At 1000 K the equilibrium pressures of the three gases in one mixture were
Vsevolod [243]

Answer:K_p for the reaction is 3.45

Explanation:

The balanced chemical reaction is:

          2SO_2(g)+O_2(g)\rightleftharpoons 2SO_3(g)                  

At eqm.   0.562 atm   0.101 atm    0.332 atm

As we are given that:

The expression of K_p for above equation follows:

K_p=\frac{(p_{SO_3})^2}{(p_{SO_2})^2\times p_{O_2}}

Putting values in above equation, we get:

K_p=\frac{(0.332)^2}{(0.562)^2\times 0.101}=3.45

The value of K_p for the reaction is 3.45

1.) Give the formula for the alkane containing 500 carbons.
Alinara [238K]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the concept of General organic chemistry.

1.) The formula for alkanes is Cn H2n+2

===> here n = 500, hence we get as,

C500, 2n+2 = 2(500)+2 ==> 1000+2 ==> 1002

hence the formula is ==> C500 H1002

2.) The formula for alkenes is,

CnH2n

hence, here n = 15

so we get as,

===> C15 H30
