Answer:
The principle of uniformitarianism describes the fact that the geological processes used to occur in the past were in the same manner and with the same intensity that as they occur in the present on the planet Earth. Therefore, uniformity in the geological processes exhibit from the unknown and unobservable past to present scenario of Earth. The present is the key to the past is the slogan of the principle of uniformitarianism.
An electron configuration that is farther away from 8 or 1, an electron valence that is either closer to 8 or 1 will become less stable. This is because they will either by trying hard to loose an electron to have a full 8 or gain one to become. Full 8 valence
Answer:
Magnesium has an outer energy level of n=3 with two electrons in in its energy level. Therefor Magnesium has 2 valance electrons.
Explanation:
Answer:
2.71*10^24 formula units in 4.5 moles NaCl
Explanation:
Remark
Make sure you know what a formula unit it. In this case, what it consists of is 1 ion of Na+ Combined with 1 ion of Cl- Together they combine to make NaCl which is ordinary table salt.
1 mole contains 6.02 * 10 ^23 formula units of any chemical -- in this case NaCl.
Therefore 4.50 moles have 4.5 * 6.02*10^23 formula units.
Answer:2.71*10^24
Answer:
The value for the equilibrium constant for the reaction at 298K .
What would be the value for the equilibrium constant for the following reaction at the same temperature?
Explanation:
The Kc value for the reverse reaction of the first reaction that is:
For the reverse reaction,
So, it is the inverse of the first Kc value.
Hence, the new Kc value is:
Answer is :
Kc=2.5*10^-25.
