How many atoms are present in 0.0845 moles of tungsten?

klasskru [66]

1 mole tungsten ------------- 6.02 x 10²³ atoms
0.0845 moles ---------------- ( atoms tungsten )

atoms tungsten = 0.0845 x ( 6.02 x 10²³) / 1

atoms tungsten = 5.08 x 10²² / 1

= 5.08 x 10²² atoms of tungsten

hope this helps!

Which electron configuration represents a potassium atom in excited state

Anestetic [448]

Answer: The electronic configuration of potassium atom in excited state is $1s^22s^22p^63s^22p^64s^04p^1$

Explanation:

There are 2 states classified under energy levels:

1. Ground state: This is the lower energy state which is termed as stable state.

2. Excited state: This is the upper energy state and is termed as the unstable state. All the electrons which are present in this state always come back to the ground state.

Ground state electronic configuration of potassium (Z = 19) : $1s^22s^22p^63s^22p^64s^1$

As, only 1 electron can freely move to upper state. Hence, the excited state electronic configuration of potassium will be: $1s^22s^22p^63s^22p^64s^04p^1$

Show how to carry out the transformation of benzene to chlorobenzene by going through a diazonium intermediate.

steposvetlana [31]

Following steps are involved in this reaction,
Nitration: Nitration of benzene yield nitrobenzene.
Reduction: Reduction of Nitrobenzene yield Aniline.
Diazotization: Diazonium alt of benzene is formed from aniline.
At last diazonium salt is reacted with CuCl to yield chlorobenzene.

The discovery of a very early form of helium supports the big bang theory because _____.

Amiraneli [1.4K]

Answer:

The discovery of early helium supports the Big Bang Theory because helium is something that would have been a product of a large explosion. Helium is also the most proliferate element in the universe.
