Hey there!
Label A: Sublimation
Label B: Condensation
Label C: Melting
Remember sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Condensation is the conversion of a vapor or gas to a liquid. Melting is becoming liquefied by heat.
Hope this helps!
The mass of 8 mol of ¹²C is 96 g.
Mass = 8 mol × (12 g/1 mol) = 96 g
548.6 it would be the same thing
Answer:
B. Some of the absorbed energy is converted into potential energy, and some is converted into kinetic energy
Explanation:
Answer:
0.06819 atm or 51.8559 torr
Explanation:
To solve this problem we will use the following equation:
ln(P1/P2) = H (vap) / R (1/T2- 1/T1)
Given data:
P1= 760 torr
P2= ?
T1= 78.4 °C+273 = 351.4 K
T2= 19°C + 273 = 292 k
heat of vaporization = 38.56kJ/mol
Now we will put the values in equation:
ln (760 torr/ P2) = 38.56 × 1000 j/ 8.314 j k-1 (1/ 292 - 1/ 351.4)
ln (760 torr/ P2) = 2.6849
760 torr/ P2 = 14.656
P2 = 51.8559 torr
or
P2= 51.8559 torr × 0.001315 atm
P2 = 0.06819 atm
