Assume ideal gas behavior, then solve for the total number of moles:
PV = nRT
(5.50 atm)(10 L) = n(0.0821 L-atm/mol-K)(23+273 K)
n = 2.263 mol
Moles methane: 8 g ÷ 16.04 g/mol = 0.499 mol
Moles ethane: 18 g ÷ 30.07 g/mol = 0.599 mol
Moles propane: 2.263 - (0.499+0.599) = 1.165 mol
Applying Raoult's Law:
Partial pressure = Mole fraction * Total Pressure
<em>Partial Pressure of Methane = (0.499/2.263)(5.5 atm) = 1.21 atm</em>
<em>Partial Pressure of Ethane = (0.599/2.263)(5.5 atm) = 1.46 atm</em>
<em>Partial Pressure of Propane = (1.165/2.263)(5.5 atm) = 2.83 atm</em>
The numbers in the powers are the number of electrons in a specific orbital. so you can add them to find the atomic number

Answer:
Chemical reaction
Explanation:
The physical form of potassium metal and chlorine gas are being formed, meaning there is an involvement of the rearrangement of the molecular or ionic structure.
Explanation:
Increase of temperature decreases the coordination number, e.g. upon heating to 760 K, the CsCl type crystal structure having coordination 8:8 changed to NaCl type crystal structures having coordination 6:6.
