How many vance electrons does neon need to be stable

1 answer:

8 0

An element is stable when it has a full outershell.
Generally, most shells after the first can hold 8 electrons.
The first shell can only hold 2

So in order for neon to be stable it must have a full outer shell
The first shell can hold 2
Neon has 10 electrons
10-2=8
The second shell can hold 8
And neon has 8 electrons left

So it must have 8 valence electrons to be stable

A 0.211 g sample of carbon dioxide, CO2, has a volume of 560 mL and a pressure of 429 mmHg whats the temperature of the gas in K

SCORPION-xisa [38]

The temperature of the gas sample is 813 K.

<u>Explanation:</u>

We have to use the ideal gas equation to find the temperature of the gas sample.

The ideal gas equation is PV = nRT

Pressure, P = 429 mm Hg = 0.56 atm

Volume, V = 560 mL = 0.56 L

R = gas constant = 0.08205 L atm mol⁻¹K⁻¹

Mass = 0.211 g

Molar mass of carbon di oxide = 44.01 g / mol

Moles, n = $$\frac{given mass}{molar mass} = \frac{0.211 g}{44.01 g/mol}$

= 0.0047 mol

Now, we have to plugin the above values in the above equation, we will get the temperature as,

$$T= \frac{PV}{nR}$

T = $$\frac{0.56 \times 0.56}{0.08205 \times 0.0047}$

= 813 K

So the temperature of the gas sample is 813 K.

A filament at which temperature would have the most light absorbed by a piece of yellow glass?

stepladder [879]

Soft light (answer) is the filament between (2700k-3000k).
The higher the kelvin number the whiter the light.

3500k-4100k is bright white/cool white

5000k-6500k is daylight

\and those are the three primary colors of color temperature
