The name of the element whose third shell has 2p electrons is neon.
According to Clausius-Clayperon equation,
is the vapor pressure at boiling point = 760 torr
is the vapor pressure at T_{2} =638.43 torr
Temperature
Δ
Plugging in the values, we get
ln
Therefore, the boiling point of octane = 389 K - 273 =
PV = nRT
P is pressure, V is volume, n is number of moles, R is the gas constant, T is temperature in K
(2.85 atm)(12.5 L) = (n)(.08206)(27 C + 273)
n = 1.45 moles x 35.45 grams / mol Cl2 = 51.3 grams
An example for how the Paleozic
supercontinent ice cap melted is through plants dying off, which in turn, increased the greenhouse effect.
To add, <span>the
trapping of the sun's warmth in a planet's lower atmosphere due to the greater
transparency of the atmosphere to visible radiation from the sun than to
infrared radiation emitted from the planet's surface is called the greenhouse
effect.</span>
