Question 3 (10 points) How many valence electrons are in a neutral atom of Neon-212

Chemistry
1 answer:
Rus_ich [418]3 years ago
8 0
Since neon has 8 valence electrons, a full octet makes neon stable. It is also a noble gas. Then, you do the configuration...

1s2 2s2 2p6

2s holds 2 valence electrons while 2p has 6 that equals a full octet.

A 2.50-l volume of hydrogen measured at â196 °c is warmed to 100 °c. calculate the volume of the gas at the higher temperature
ivann1987 [24]

To solve this we assume that the hydrogen gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 = (100 + 273.15) K x 2.50 L / (-196 + 273.15) K

<span>V2 = 12.09 L</span>

Therefore, the volume would increase to 12.09 L as the temperature is increased to 100 degrees Celsius.
