The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.

<h3>What is Molecular Orbital Theory?</h3>

According to this theory,

Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
The shape of molecular orbitals formed depends on the type of atomic orbitals combined
Only atomic orbitals having comparable energies and the same orientation can intermix
Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
Bonding M.O. is represented by $\sigma, \pi, \delta$ while Antibonding M.O. is represented by $\sigma^*, \pi^*, \delta^*\\$

For a particular reaction at 235.8 °C, ΔG=−936.92 kJ/mol , and ΔS=513.79 J/(mol⋅K) . Calculate ΔG for this reaction at −9.9 °C.

Rudik [331]

Answer:

-138.9 kJ/mol

Explanation:

Step 1: Convert 235.8°C to the Kelvin scale

We will use the following expression.

K = °C + 273.15 = 235.8°C + 273.15 = 509.0 K

Step 2: Calculate the standard enthalpy of reaction (ΔH°)

We will use the following expression.

ΔG° = ΔH° - T.ΔS°

ΔH° = ΔG° / T.ΔS°

ΔH° = (-936.92kJ/mol) / 509.0K × 0.51379 kJ/mol.K

ΔH° = -3.583 kJ (for 1 mole of balanced reaction)

Step 3: Convert -9.9°C to the Kelvin scale

K = °C + 273.15 = -9.9°C + 273.15 = 263.3 K

Step 4: Calculate ΔG° at 263.3 K

ΔG° = ΔH° - T.ΔS°

ΔG° = -3.583 kJ/mol - 263.3 K × 0.51379 kJ/mol.K

ΔG° = -138.9 kJ/mol

Given the following isotopes of strontium, calculate the average atomic mass.

vodka [1.7K]

Answer:

87.5198

Explanation:

(43.65 * 87.05) + (48.25 * 87.93) + (8.11 * 87.50) = 8751.98

8751.98 / 100 = 87.5198

Arranges the following molecules in order of increasing dipole moment: <br> H2O, H2S, H2Te, H2Se.

erastova [34]

Explanation:

Dipole moment is defined as the measurement of the separation of two opposite electrical charges.

$H_{2}O$ is a bent shaped molecule with a dipole moment of 1.87.

$H_{2}S$ is also a bent shaped molecule with a dipole moment of 1.10.

$H_{2}Te$ is a also a bent shaped molecule and has a negligible dipole moment.

$H_{2}Se$ has a dipole moment of 0.29.

Therefore, given molecules are arranged according to their increasing dipole moment as follows.

$H_{2}Te$ < $H_{2}Se$ < $H_{2}S$ < $H_{2}O$

A mole of cu atoms has the same number of atoms as a mole of he atoms. true false

Ronch [10]

True. A mole is a standard unit of measurement. It's like that riddle; "What's heavier, a pound of bricks or a pound of feathers? Neither- a pound is a pound no matter what it's made of."
