Violet light has a wavelength of 422 nm, how much energy is found in this photon of violet light?
pashok25 [27]

Answer:

3.025eV

Explanation:

Energy of a photon is given by

E=hν

Where h is the Planck's constant

And ν represents the frequency of the photon .

Now for violet light wavelength λ=410nm= 410x10^-9m

By using the formula ν=c/λ

where c represents speed of light I.e 3 x 10^8 m/s

Calculating energy of violet photon we have

E=hc/λ

h=6.626 x 10^-34 J.s

On inserting the value in the formula , we get

E= 4.848 x 10^-19 Joules

To convert it into electron volts we need to divide it by 1.602 x10^-19.

The final result what we have is E=3.026eV.

Note: the result calculated is according to the above value . result may vary according to the values taken .

Why does a 4 carbon linear alkane, butane c4h10, have two more hydrogens ?
Scilla [17]
Alkanes are hydrocarbons that only contain single bonds in them. A carbon can bond with up to 4 atoms, even with another carbon atom. So, in a C-C bond, 3 more H atoms can bond to each of the C atom. Generally, the chemical formula for alkanes is CₓH₂ₓ₊₂. So for butane, there are 4 C atoms. The corresponding H atoms are 2(4) + 2 = 10. That's why it's chemical formula is C₄H₁₀.

What is similar about the atomic structure of the copper isotopes?
jasenka [17]
All copper atoms have atomic number 29: all their nuclei contain 29 protons. But they also contain uncharged particles called neutrons. ... The two different kinds of atom are called isotopes of copper. The neutron has a mass very similar to that of the proton, so the two isotopes differ in mass.

How does the suns energy contribute to the movement of water in the water cycle?
Troyanec [42]

Answer:Evaporation

Explanation:

The suns heat speeds the movement of water molecules, until the molecules move fast enough that they jolt out the surface of the water individually. Overtime the water gradually evaporates into water vapor.
