Convert the following Celsius temperatures to the Kelvin scales

Extend the aufbau sequence through an element that has not yet been identified, but whose atoms would completely fill 7p orbital

Thepotemich [5.8K]

Answer:

Number of electrons = 118

Electronic configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶

Explanation:

Given: A chemical element that has completely filled 7p orbital.

According to this, the principal occupied electron shell or the valence shell of such an element is 7p.

⇒ the principal quantum number (n) for the valence shell is 7.

∴ this element belongs to the period 7 of the periodic table.

Also, an element that has completely filled p-orbital belongs to the group 18 of the p-block.

Therefore, an element that belongs to the group 7 and period 18 of the periodic table, should have a completely filled 5f, 6d, 7s and 7p orbitals.

Therefore, the electronic configuration should be: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶

And, the number of electrons = atomic number of radon (Rn) + 14 + 10 + 2 + 6 = 86 + 32 = 118.

Therefore, the given element has atomic number 118 and has the electronic configuration: [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶. Thus the given element can be Oganesson.

Which best explains why water has a much higher boiling point than would otherwise be predicted?

ikadub [295]

My guess is that water is a liquid and not a solid, or a gas. It can be heated by us or by the suns rays, which if done by the suns rays the water azorbs the light rising the temp to the point of boil which then makes the water evaporate into the air, and thus making cloud in the sky that we see all the time thus when the clouds become big enough it begins to rain. ( also called the water cycle)

Bonjour, quelqu’un pourrait-il m’aider avec ce numéro , (#13)

suter [353]

Answer:

La réponse ce trouve en bas

Explanation:

13 a) Oui, ce possible parce la solubilité du sel dans l'eau a 60° est majeur que 50g du sel en 150 ml d'eau (333.3 g/L). Dans la graphique la solubilité est de 370 g/L.

b) Jusqu'au 30°C, (30°, 360g(L), ce trouvent ces points dans la ligne rouge.
