Select ALL answers that apply to the total energy of a wave:
Verdich [7]

Answer:

(A) The shorter the wavelength, the more total energy the wave contains.

(B) The longer the wavelength, the less total energy the wave contains.

Explanation:

The wavelength (λ), frequency (f) and energy (E) are interrelated. This relationship between them is represented in the following equations:

λ = v/f and E = hf

Where;

λ = wavelength (m)

f = frequency (Hz)

E = energy (Joules)

v and h represents speed of light and Planck's constants respectively.

Combining both equations, E = hc/λ

This equation shows that ENERGY (E) is directly proportional to the frequency (f) but inversely proportional to the wavelength (λ). This means that "the shorter the wavelength, the more total energy a wave contains" and vice versa.

However, the higher the frequency, the more the total energy the wave contains and vice versa.

How acetophenone can be converted to phenol by reaction?
zysi [14]

Answer:

m-CPBA followed by base catalysed hydrolysis

Explanation:

The scheme of this reaction is shown in the image attached.

We can see here that the acetophenone reacts with metachloroperoxybenzoic acid (m-CPBA) as shown in the image to yield phenyl acetate.

Phenyl acetate is now hydrolysed by a base as shown to yield the acetate ion and phenol.

What is the percent composition by mass of aluminum in Al2(SO4)3 (gram-formula mass = 342 grams/mole)?
Aliun [14]
The atomic mass of Aluminum is around 27 amu. There are two aluminum atoms, so it takes 54 amu. The gram-formula states that 1 mole of this compound has 342 grams. By definition, this means that the total amu of this compound is 342. Therefore, we divide 54 by 342 to get around 15.8 %.

What made Mendeleev certain that he should leave gaps in his table?
ser-zykov [4K]

Answer:

Mendeleev left gaps in his periodic table because he knew that these elements existed, but had not yet been discovered. He believed that the elements would be eventually found and would fit perfectly into the gaps. Two such elements are Germanium and Gallium.
