Answer: Vanadium -23 has an electronic configuration of
[Ar]3d3 4s2 (e)
Explanation:
Vanadium has an atomic number of 23 . The total number of electrons in all the subshells will also be 23 .
For (a) [ Ar] has an 18 electrons already, adding 2 from 3s subshell 7 from 3p subshell makes it 27 electrons which is greater than 18. Also, it doesn't conform with the rule of electronic configuration.
(b) [ Ar] has an 18 electrons already, adding, adding 4 from 3s orbital and 5 from 3p orbital makes it 27 which is greater than 23.
(c) [ Ne] has an 10 electrons already, adding, 3 from 3s and 3 from 3p makes it 16. Which is less than 23
(d) [ Ne] has an 10 electrons already, adding, 4 from 3s and 1 from 3p makes it 14 . Which is less than 23.
(e)[ Ar] has an 18 electrons already, adding, 3 from 3d subshell and 2 from 4s subshell makes it 23.
Therefore [Ar]3d3 4s2 is the condesed electronic configuration of Vanadium.
Explanation:
Basically
The concentration of reactants and the products becomes equal at equilibrium. The equilibrium position is changed if the concentration of the species in the mixture is changed.
- the disturbance causes a change in Q; the reaction will shift to re-establish Q=K.
Answer:
It is called Sulfur dichloride
Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.
What are Molecules ?
Molecules are the combination of two or more different atoms combine in a fixed ratio.
Molecules can be independently founded.
Atoms are always founded in combined state and does not occurs independently except rare earth elements which belongs to 18th group of periodic table.
Chemicals are taken in compound state But they undergo chemical reaction individually in molecular level.
Hence, Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.

Answer:
A. Condensation
B. Evaporation
Explanation:
Condensation releases energy when water vapor condenses to form water droplets. Evaporation absorbs energy whenever it changes from liquid to gas, the heat from the sun heats the water up and absorbs energy.
