Answer:
No.
Explanation:
1. Volume of a rice grain
There is no standard for the size of a rice grain, so let's make an arbitrary assumption.
An average rice grain behaves as if it were a rectangular solid with dimensions 7 mm × 2 mm × 2 mm.
The volume of one rice grain is
V = lwh = 7 mm × 2 mm × 2 mm = 28 mm³
Convert to cubic metres
:
2. Volume of the room
V = lwh = 30.0 m × 8.5 m × 3.5 m = 890 m³
3. Volume of a mole of rice
4. Conclusion
The room is not big enough to hold a mole of rice.
If you work it out, you will find that it takes about
20 000 000 000 000 (twenty trillion) rooms to hold a mole of rice.
The electronic transition that will produce the lowest frequency is an electron falling from the 3rd to the 2nd energy level.
The question is incomplete, the complete question is;
As electrons fall from high energy orbitals to lower orbitals, energy is released in the form of electromagnetic radiation. The farther the electron falls, the more energy is released. Which of the following electronic transitions would produce a wave with the lowest frequency?
an electron falling from the 6th to the 2nd energy level
an electron falling from the 5th to the 2nd energy level
an electron falling from the 3rd to the 2nd energy level
an electron jumping from the 1st to the 2nd energy level
According to Bohr's theory, energy is absorbed or emitted when an electron moves from one energy level to another. This energy often occurs as visible light of known frequency and wavelength.
The magnitude of frequency of light depends on the difference in energy between the two energy levels. If the difference between the energy levels is high, the frequency of light is also high and vice versa.
The transition from 3rd to the 2nd energy level represents a low frequency transition because the energy levels are close together.
