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

Would you expect a carbon atom to have the same mass as an oxygen atom
kramer
Its impossible coz carbon has isotopes C-12 and C-13 whereas oygen has isotopes 16<span>O, </span>17<span>O, and </span>18<span>O, so impossible. Hope it helps</span>

For the aqueous reaction dihydroxyacetone phosphate is the reactant and glyceraldehyde 3 phosphate is the product. dihydroxyacet
lbvjy [14]

<u>Answer:</u> The Gibbs free energy of the reaction is -445 J/mol.

<u>Explanation:</u>

The chemical equation for the conversion follows:

\text{Dihydroxyacetone phosphate}\rightleftharpoons \text{Glyceraldehyde-3-phosphate}

The expression for K_{eq} of above equation is:

K_{eq}=\frac{\text{[Glyceraldehyde-3-phosphate]}}{\text{[Dihydroxyacetone phosphate]}}

We are given:

[Glyceraldehyde-3-phosphate] = 0.00400 M

[Dihydroxyacetone phosphate] = 0.100 M

Putting values in above equation, we get:

K_{eq}=\frac{0.004}{0.100}=0.04

Relation between standard Gibbs free energy and equilibrium constant follows:

\Delta G=\Delta G^o+RT\ln K_1

where,

\Delta G^o = Standard Gibbs free energy = 7.53 kJ/mol = 7530 J/mol  (Conversion factor: 1kJ = 1000J)

R = Gas constant = 8.314J/K mol

T = temperature = 298 K

Putting values in above equation, we get:

\Delta G=7530J/mol+(8.3145J/Kmol)\times 298K\times \ln (0.04)\\\\\Delta G=-445J/mol

Hence, the Gibbs free energy of the reaction is -445 J/mol.
