Explanation:
The given data is as follows.
Energy needed for 1 mole = 279.7 kJ =
= 279700 J
Therefore, energy required for 1 atom will be calculated as follows.
=
As relation between energy and wavelength is as follows.
E =
where, h = planck constant =
c = speed of light =
= wavelength
Therefore, putting given values into the above formula as follows.
E =
=
=
or, = m
= 428 nm
Thus, we can conclude that the maximum wavelength of light that can remove an electron from an atom on the surface of lithium metal is 428 nm.
Answer:
A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.
Explanation:
Answer and Explanation:
a. The equation of K of this reaction is shown below:-
3 A + 5 B + 4 C↔5 D + 7 E + F
b. The moles of compound F is shown below:-
3 A + 5 B + 4 C↔5 D + 7 E + F
2 moles
Now, the mole of produced is
Now, we will the value of c by using the above equation
After solving the above equation we will get
0.5 moles
Answer:
Two Sections that contain nitrogen of a nucleotide that bond together to connect strands of DNA or RNA.
Explanation:
Using the ideal gas law, for a constant temperature, pV = constant (also known as Boyle's Law)
(1 atm)(175 L) = (5.2 atm)(V) = constant
V = 33.7 L
