Solution:
1. Determine the frequency:

E=hv
6.24 x 10-19 J = (6.626 x 10-32 Js) x (v)
v = 9.417 x 10^14 s-1

2. Determine the wavelength:

<span>λv = c
</span><span>(λ) x (9.417 x 10^14 s-1) = 3.00 x 10^8 m/s
</span><span>λ = 3.18 x 10-7 m
</span>
Wavelength (<span>λ) = </span>318nm

What is best classified as a physical change?
andrew-mc [135]

A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not. Physical changes can further be classified as reversible or irreversible. The melted ice cube may be refrozen, so melting is a reversible physical change.

Compare the densities of hydrogen, oxygen, and water.
riadik2000 [5.3K]

Answer:

Water is a compound made up of two elements—hydrogen and oxygen. ... They are both colorless, odorless gases , and they both readily react with other elements—making them "reactive" elements. But in many ways they are very different from each other. Hydrogen has the lowest density of all the elements.
