Answer:

Atoms form chemical bonds to make their outer electron shells more stable. The type of chemical bond maximizes the stability of the atoms that form it. ... Covalent bonds form when sharing atoms results in the highest stability. Other types of bonds besides ionic and covalent chemical bonds exist, too.

This set contains the spectra of benzil, biphenyl, and bibenzyl, three compounds used in the melting point experiment. Using you

murzikaleks [220]

Answer:

Spectrum 1- Biphenyl

Spectrum 2 - Benzil

Spectrum 3 - Bibenzyl

Explanation:

For Benzil:

The Spectrum - 2 shows this compound.The C=O and C-H bond stretching observed at following values.

$C=O \,at\,1657cm^{-1}$

$C=H \,at\,3063cm^{-1}$

For Biphenyl:

Spectrum - 1 shows this compound.

There are stretching vibrations from $3061, 3032\,and \,1597 -1428cm^{1}$ due to C-H stretching and C-C stretching respectively of aromatic ring only.

For Bibenzyl:

Spectrum - 3 shows this compound

There are stretching vibrations at $3057,3026 and 1598 - 1449cm^{-1}$ due to C-H stretching and C-C stretching of aromatic ring.

Along with this, stretching vibrations at $2943 - 2917 cm^{-1}$ due to C-H of alkyl.

If a system performs 147 kJ of work while receiving 47 kJ of heat, what is change in its internal energy?

Verdich [7]

Answer:

-100 kJ

Explanation:

We can solve this problem by applying the first law of thermodynamics, which states that:

$\Delta U = Q-W$

where:

$\Delta U$ is the change in internal energy of a system

Q is the heat absorbed/released by the system (it is positive if absorbed by the system, negative if released by the system)

W is the work done by the system (it is positive if done by the system, negative if done on the system)

For the system in this problem we have:

W = +147 kJ is the work done by the system

Q = +47 kJ is the heat absorbed by the system

So , its change in internal energy is:

$\Delta U = +47 - (+147) =-100 kJ$

If 74.5 m of oxygen are collected at a pressure of 98.0 kPa, what volume will the gas occupy if the

sergey [27]

Answer:

80.8 mL

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 74.5 mL

Initial pressure (P₁) = 98.0 kPa

Final pressure (P₂) = 90.4 kPa

Final volume (V₂) =?

The final volume of the gas can be by using the Boyle's laws equation as follow:

P₁V₁ = P₂V₂

98 × 74.5 = 90.4 × V₂

7301 = 90.4 × V₂

Divide both side by 90.4

V₂ = 7301 / 90.4

V₂ = 80.8 mL

Thus, the volume of the gas is 80.8 mL
