Which two elements in the periodic table have the same number of electrons in their outer orbitals?

1 answer:

8 0

It has to do with what group number they are in so an example of two electron with the same number of electrons in their outer orbitals would be...

Oxygen & Sulfur (O & S)

PV / T = P'V' / T'

V = V'

P / T = P' / T'

P = 630 mmHg
T = 100 K
P' = 1760 mmHg
T' = ?

630 / 100 = 1760 / T'

T' = 1760 / 6,3

T' = 279,36 K

T' ≈ 280 K

The graph shows the solubility of several different salts in water, across a range of temperatures. According to the

sladkih [1.3K]

Answer:

Sodium chloride

See the graph attached

Explanation:

The attached graph with a green and a red arrow facilitates the understanding of this explanation.

To read the solubility on the graph, you can start with the temperature, on the x-axis.

The red vertical arrow shows how, departing from the 40ºC temperature on the x-axis, you intersect the solutibility curve of sodium chloride at a height (y-axis) corresponding to 60 g/100cm³ of water (follow the green horizontal arrow).

Hence, sodium chloride is the salt that can dissolve at a concentration of about 60g/100cm³ of water at 40ºC.
