Answer:
Sodium has 1 valence electron and bismuth has 83 electrons (5 valence electrons)
Explanation:
Let the water evaporate and you'll be left with the sugar, or boil the water and collect the steam. the sugar will be left in the container you boiled the water in and you'll still have the water from the steam.
The chemical symbol for sodium is Na
Answer:
P2 = 0.935 atm
Explanation:
initial conditions:
∴ V1 = 3.41 L
∴ T1 = - 91.5 °C + 273 = 181.5 K
∴ P1 = 3990 torr * ( atm / 760 torr ) = 5.25 atm
∴ R = 0.082 atm.L / K.mol
⇒ n = P1V1 / RT1 = ((5.25 atm)*(3.41 L)) / ((0.082 atm.L/K.mol)*(181.5 K))
⇒ n = 1.107 mol
final conditions:
∴ V2 = 3.3 L
∴ T2 = - 239 °C = 34 K
∴ n = 1.107 mol
⇒ P2 = nRT2 / V2
⇒ P2 = ((1.107 mol)*(0.082 atm.L/K.mol)*(34 K)) / 3.3 L
⇒ P2 = 0.935 atm
