What is degenerate orbitals

1 answer:

5 0

Two or more orbitals that have the same energy are called degenerate orbitals. Those orbitals are different in a way that they are displayed differently in space around nucleus, but they are associated in the same energy. E.g., the three subshells of p orbital are px, py, and pz.

Answer : The final chamber pressure is 0.746 atm.

Explanation:

First we have to calculate the moles of $KClO_3$ .

Molar mass of $KClO_3$ = 122.5 g/mole

$\text{ Moles of }KClO_3=\frac{\text{ Mass of }KClO_3}{\text{ Molar mass of }KClO_3}=\frac{2.00g}{122.5g/mole}=0.0163moles$

Now we have to calculate the moles of $O_2$ .

The balanced chemical reaction will be:

$2KClO_3\rightarrow 2KCl+3O_2$

From the balanced reaction we conclude that,

As, 2 moles of $KClO_3$ react to give 3 moles of $O_2$

So, 0.0163 moles of $KClO_3$ react to give $\frac{3}{2}\times 0.0163=0.0244$ moles of $O_2$

Now we have to calculate the pressure of gas.

Using ideal gas equation:

$PV=nRT$

where,

P = pressure of gas = ?

V = volume of gas = 0.800 L

T = temperature of gas = $25.0^oC=273+25.0=298K$

R = gas constant = 0.0821 L.atm/mole.K

n = number of moles of gas = 0.0244 mole

Now put all the given values in the ideal gas equation, we get:

$P\times (0.800L)=0.0244mole\times (0.0821L.atm/mole.K)\times (298K)$

$P=0.746atm$

Therefore, the final chamber pressure is 0.746 atm.

Answer:

No photoelectric effect is observed for Mercury.

Explanation:

From E= hf

h= Plank's constant

f= frequency of incident light

Threshold Frequency of mercury= 435×10^3/ 6.6×10^-34 × 6.02×10^23

f= 11×10^14 Hz

The highest frequency of visible light is 7.5×10^14. This is clearly less than the threshold frequency of mercury hence no electron is emitted from the mercury surface

Answer:

$1.9 \times 10^{6}\text{ m/s}$

Explanation:

$v_{\text{rms}} = \sqrt{\dfrac{3RT}{M}$

Data:

T = 3.02 × 10⁸ K

M = 2.013 × 10⁻³ kg/mol

Calculation:

$v_{\text{rms}} = \sqrt{\dfrac{3\times 8.314\text{ J}\cdot\text{K}^{-1} \text{mol}^{-1} \times 3.02 \times 10^{8} \text{ K}}{2.014 \times 10^{-3} \text{ kg}\cdot \text{mol}^{-1}}}\\\\\\=\sqrt{3.740\times 10^{12} \text{ (m/s)}^{2}} = 1.9 \times 10^{6}\text{ m/s}$
