2.55 moles H20 will be produced
Answer:
The answer to your question is: 79.6 L
Explanation:
Data:
n = 60 moles
Pressure = P = 20.0 atm
Temperature = T = 50°C
Volume = V = ?
Convert temperature to Kelvin
°K = 273 + 50
°K = 323
Formula (ideal gas law)
PV = nRT solve for V
V = nRT / P
V = (60)(0.08206)(323) / 20 Substitution
V = 1590.32 /20
V = 79.6 L
When it comes to physical changes like phase changes, there are two types of heat energy: sensible heat and latent heat. Sensible heat is the heat absorbed/released when you heat the substance but it doesn't change phase. An example would be heating lukewarm water. The substance is liquid all throughout. Latent heat, on the other hand, is the heat absorbed/released when there is a phase change. An example would be boiling water, because it changes liquid to vapor.
Hence, for freezing liquid, you use the latent heat, specifically the heat of fusion. The answer should be
2.5 g * (1 mol/18.02 g) * 6.03 kJ/mol = 0.84 kJ/mol
The answer is not in the choices. You only use Hvap if you boil water.
C is the correct answer I think
C or the last one because you can tell they they put no effort in c but they put to much to trick you in f
