Because in CH4 the valence electrons of Carbon are being pulled away from the nucleus with the same force (since all hydrogen has the same electronegativity).So charges are equally distributed throughout the atom and the atom is non-polar. In CH3Cl Cl has a different electronegativity than H, so charges aren't equally distributed and therefore the molecule is polar.

pH=6.98
Explanation:
This is a very interesting question because it tests your understanding of what it means to have a dynamic equilibrium going on in solution.
As you know, pure water undergoes self-ionization to form hydronium ions, H3O+, and hydroxide anions, OH−.
2H2O(l]⇌H3O+(aq]+OH−(aq]→ very important!
At room temperature, the value of water's ionization constant, KW, is equal to 10−14. This means that you have
KW=[H3O+]⋅[OH−]=10−14
Since the concentrations of hydronium and hydroxide ions are equal for pure water, you will have
[H3O+]=√10−14=10−7M
The pH of pure water will thus be
pH=−log([H3O+])
pH=−log(10−7)=7
Now, let's assume that you're working with a 1.0-L solution of pure water and you add some 10
Answer:
chemical energy in the form of glucose/sugar
Explanation:
Answer:
The energy of electromagnetic radiation increases as its frequency increases.
The frequency and wavelength of electromagnetic radiation are inversely proportional.
Explanation:
According to Max Plank's equation, the energy of electromagnetic radiation is given by E=hf where h= Plank's constant and f= frequency of the electromagnetic radiation. This means that the energy and frequency of electromagnetic radiation and its energy are related by a direct proportion. As frequency of the electromagnetic radiation increases, the energy of the radiation increases also.
However, frequency and wavelength of electromagnetic radiation are inversely related. The frequency decreases with increasing wavelength of electromagnetic radiation.
