Evaporation and its Effects on PCP and CresolWe are asked to explain the phenomena of how 1 gram of liquid water at 35 degrees C (as in a pond or lake) evaporating into an overlying air mass at a temp of 65 degrees C and a relative humidity of 50%.
What actually causes the evaporation of water and how can this be calculated in this instance?? What is the vapor pressure of the water?
Second, if the water contained organic contaminants such as pentachlorophenol and cresol, what are the vapor pressures of the 2 contaminants and would they evaporate before the water or would the water evaporate and leave the contaminants behind?
A zero-order reaction has a constant rate of 3.20×10-4 . If after 60.0 seconds the concentration has dropped to 6.50×10-2 , what was the initial concentration?
Imagine that you model your lungs as a 5 L sealed balloon at sea level: Estimate the volume of your lungs at 100 m below the sea level.
Given the unbalanced equation: Ag2CO3 ® Ag + O2 + CO2, how many moles of Ag can be produced from 2.5 moles of Ag2CO3.
Historically, the solid residue that is left after the Dichloromethane -or methylene chloride (CH2Cl2 )solution is evaporated has a lower melting point that its literature value, due to impurities.
Quantum number representations - What are the possible values of the four quantum numbers for one electron in a 5d orbital?
