Answer: The chemical formula for this complex is $[Cd(C_{10}H_8N_2)_2]Cl_2$ or $[Cd(bipy)_2]Cl_2$

Explanation:

2,2'-Bypridine is a bidentate chelating ligand which forms complex with many transition metals. Its chemical formula is $C_{10}H_8N_2$

Bidentate ligands are the ligands which donate two pairs of electrons to the metal atom.

This complex contains two spheres: Primary sphere and secondary sphere

Primary sphere is the sphere which satisfies the primary valency of the metal and the coordination sphere satisfies the secondary valency of the metal known as secondary sphere.

Chlorine is satisfying the primary valency of the metal and bipyridyl is satisfying the secondary valency of the metal.

The chemical formula for this complex is $[Cd(C_{10}H_8N_2)_2]Cl_2$ or $[Cd(bipy)_2]Cl_2$ and its structure is given in the image attached.

Answer:

C₃H₄O₄

Explanation:

In order to get the empirical formula of a compound, we have to follow a series of steps.

Step 1: Divide the percent by mass of each element by its atomic mass.

C: 34.6/12.01 = 2.88

H: 3.9/1.01 = 3.86

O: 61.5/16.00 = 3.84

Step 2: Divide all the numbers by the smallest one, i.e., 2.88

C: 2.88/2.88 = 1

H: 3.86/2.88 ≈ 1.34

O: 3.84/2.88 ≈ 1.33

Step 3: Multiply all the numbers by a number that makes all of them integer

C: 1 × 3 = 3

H: 1.34 × 3 = 4

O: 1.33 × 3 = 4

The empirical formula is C₃H₄O₄.

Use bond energies to determine δhrxn for the reaction between ethane and chlorine. ch3ch3(g)+cl2(g)→ch3ch2cl(g)+hcl(g)

STALIN [3.7K]

For this reaction to proceed, the following bond breaking should occur:

*one C-H bond
* one Cl-Cl bond

After, the following bond formations should occur:
*one C-Cl bond
*one H-Cl bond

Now, add the bond energies for the respective bond energies which can be found in the attached picture. For bond formations, energy is negative. For bond breaking, energy is positive.

ΔHrxn = (1)(413) + (1)(242) + 1(-328) + 1(-431) = -104 kJ
