Answer:
Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes. The visible spectrum showing the wavelengths of each of the component colours. The spectrum ranges from dark red at 700 nm to violet at 400 nm.The 'colour' of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.The reason that different waves of light appear to be different colors of light is because the color of a light wave depends on its wavelength. For example, the wavelength of blue light is about 450 nanometers, while the wavelength of red light is about 700 nanometers.
Explanation:
D. The population of fish in Location B will decrease because the water is contaminated
Explanation:
The correct statement from the given choices is that the population of fish in location B will decrease because the water is contaminated.
The use of pesticides and fertilizers will eventually run-off into nearby streams and contaminate them.
This will lead to water toxicity beyond levels that organism in the stream can bare.
- Plastic is non-biodegradable and does not pollute the air.
- Plastic has nothing to do with water absorption from the air.
- The population of honeybees will reduce because of the applied pesticides.

<span>[Ne] 3s23p2
In noble gas notation the simplification in the electron distribution to the orbitals is represented where in of all of the lower filled orbitals up to the closest noble gas is enclosed by its symbols in brackets. The remaining orbitals are written in the usual way.The electronic configuration of Si is 1s22s22p63s23p2.The electronic configuration of Ne is 1s22s22p6. Thus the Noble gas notation of silicon (Si) can be written as [Ne] 3s23p2.</span>
A pH of 7.2 would mean it is basic. 0-6 Acidic. 7 - Neutral. 8-14 - Basic.
Answer:
The valid quantum numbers are l=0, l=-2 and l= 2.
Explanation:
Given that,
n = 3 electron shell
Suppose, the valid quantum numbers are
l = 3
m = 3
l = 0
m = –2
l = –1
m = 2
We know that,
The value of n = 3
Principle quantum number :
Then the principal quantum number is 3. Which is shows the M shell.
So, n = 3
Azimuthal quantum number :
The azimuthal quantum number is l.
Magnetic quantum number :
The magnetic quantum number is
Hence, The valid quantum numbers are l=0, l=-2 and l= 2.
