Explanation:
Dipole moment is defined as the measurement of the separation of two opposite electrical charges.
is a bent shaped molecule with a dipole moment of 1.87.
is also a bent shaped molecule with a dipole moment of 1.10.
is a also a bent shaped molecule and has a negligible dipole moment.
has a dipole moment of 0.29.
Therefore, given molecules are arranged according to their increasing dipole moment as follows.

Answer:
yes it can λ =265 nm
Explanation:
Here we will use the relationship
E = h c/λ ∴ λ = E/ hc where
h= Plank's constant
c= Speed of light
λ = Wavelength = ?
Substituting
note need E in J ,
E = 4.7 eV x 1.602 x 10⁻¹⁹ J/eV = 7.5 x 10⁻¹⁹ J)
λ = 7.5 x 10 ⁻¹⁹ J / ( 6.626 x 10⁻³⁴ Js x 3 x 10^8) = 2.65 x 10⁻⁷ m = 2.65
= 2.65 x 10⁻⁷ m x 1 x 10⁹ nm/m = 265 nm
<span>Mass is a property that determines how much effort it takes to change somethings velocity. Weight is how much downward force does something exert in a gravitational field which is just the amount of gravity time the mass of an object. We use mass interchangeable with weight because everything on earth experiences the same amount of gravity or close to it, and so something that weighs twice as much as something else also has twice as much mass as that something else. Weight can actually vary for the same mass here on earth the strength of gravity changes from one place to another by small amounts, not enough to ruin your cooking recipe instructions, and weight can change dramatically for something that is falling, the strength of gravity for astronauts in orbit is not much reduced in comparison to here on earth, if there was no gravity they wouldn't go around the earth, they are weightless because they are falling and have enough sideways velocity to keep missing the earth, but their mass has not changed, it still requires effort to get them moving or to stop them.

Answer:
When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes. A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon. This process is known as distillation or carbonization.
