How many electrons are present in an atom with its 1s, 2s, 2p, and 3s subshells filled with two electrons in the 3p subshell? Wh

at is the element?
Wouldn’t it be Argon?
1s=2 electrons
2s= 2 electrons
2p= 6 electrons
3s = 2 electrons
3p= 6 electrons
Total electrons is 18 which would be Ar on periodic table.. please explain why I’m wrong

Answer:

magnesium

Explanation:

1s^2 2s^2 2p^6 3s^2 3p^2 = 14

magnesium is 14th in the periodic table

3p^2 because you have said that 3p subshell is filled with two electrons only.

Enter an equation showing how this buffer neutralizes added aqueous acid (HI). Express your answer as a chemical equation. Ident
andrey2020 [161]

Answer:

H^++NH_3\rightleftharpoons NH_4^+

Explanation:

Hello there!

In this case, since the buffer is not given, we assume it is based off ammonia, it means the ammonia-ammonium buffer, whereas the ammonia is the weak base and the ammonium ion stands for the conjugate acid. In such a way, when adding HI to the solution, the base of the buffer, NH3, reacts with the former to promote the following chemical reaction:

H^++NH_3\rightleftharpoons NH_4^+

Because the HI is totally ionized in solution so the iodide ion becomes an spectator one.

Best regards!

Explain how you would separate a mixture of water, sand, salt and iron filings into its four component parts.
katen-ka-za [31]

You would use the density difference to separate the sand, evaporate the water out (the water vapor will cool back to water if collected). Then use a magnet to get the iron fillings out of the salt.
