What is the Nobel gas notation for selenium​
seraphim [82]

Answer:

Se =[Ar] 3d¹⁰ 4s² 4p⁴

Explanation:

The noble gas notation is used for the shortest electronic configuration of other periodic table elements.

For example:

The atomic number of Argon is 18, and its electronic configuration is,

Ar₁₈ = 1s² 2s² 2p⁶ 3s² 3p⁶

The atomic number of selenium is 34, its electronic configuration is,

Se₃₄ = 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁴

By using the noble gas notation, electronic configuration of selenium can be written is shortest form.

Se =[Ar] 3d¹⁰ 4s² 4p⁴

This electronic configuration is also called abbreviated electronic configuration.

Predict the direction in which the equilibrium will lie for the reactionC6H5COO- + HF C6H5COOH + F-.Ka(C6H5COOH) = 6.5 x 10-5; K
Llana [10]

Answer:

Equilibrium will lie to the right.

Explanation:

K_{a}(HF)> K_{a}(C_{6}H_{5}COOH)

That means HF is stronger acid than C_{6}H_{5}COOH.

Alternatively, it can be said that C_{6}H_{5}COO^{-} is a stronger base than F^{-}.

Therefore HF readily gives proton to C_{6}H_{5}COO^{-} to form C_{6}H_{5}COOH and F^{-} than the reverse reaction.

So, the equilibrium will lie more towards the right i.e. towards formation of C_{6}H_{5}COOH and F^{-}.

MANY DIE BECAUSE OF CORONA VIRUS But after analyzing the playback backwards, it turns out that fear of being exposed to the viru
monitta

Answer:

This is completely wrong. How could you possibly think like this?

Explanation:

First of all, wearing a mask excessively does not change the oxygen you breathe. It does, however, change <em>how</em> you breathe. You still breathe the same air, but your lungs are different.

Second of all, we do not breathe in more carbon dioxide, because it gets filtered out. (Side note: we don't 'excrete' carbon dioxide, we just filter it out of the air.)

Third of all, "taking medicine & supplements too much results in Stomach & HEART is weak." What medicine have we taken? The vaccine, (of which I will not state my opinions), but other than that, there are no medicines that the general populace has taken.

Lastly, fourth of all, how did we mishandle the pandemic? There are currently 197 million people that have gotten sick worldwide. Do you know how many more people would be sick if we hadn't done what we did?

Please research your beliefs before you post them on any site. Also, please do not post anything politics- or religious- based on Brainly, as that hits nerves for some people, like me.
