a) A closed tank contains steam with 20% moisture at 3 bar. Heat is added until one of the two phases disappears. Which phase disappears and what is the final pressure and temperature? b) Another closed tank contains steam with 99.9 % moisture at 3 bar. Heat is added until one of the two phases disappears. Which phase disappears and what is the final pressure and temperature? c) A third closed tank contains a vapor-liquid mixture of toluene at 1 atm. Ninety-eight percent of the toluene (by mole) is in the liquid phase. Heat is added until one of the two phases disappears. Which is the phase that disappears?
Solid NH4NO3 (ammonium nitrate) decomposes on heating to 400°C, forming N2O gas and water vapor, H2O. (a)Write a balanced chemical equation
Analysis of these publications outline the chiral ligands used and draw a catalytic cycle for one initermolecular and one intramolecular reaction - the asymmetric Heck reaction
Use the total energy of charge distribution to calculate the total electrostatic energy of a uranium 235 nucleus. It has 92 protons and a radius of about 7.0 femtometers?
Define what is meant by the numerical aperture and explain why the lens is oil filled. Using the Rayleigh Criteria, define the smallest resolvable features when light of wavelength 633 nm is used to illuminate the substrate and the oil filled obje..
Aim To understand the fundamentals of chemical bonding and ionic equilibrium and its application in engineering problems.
Here you compare the value of H when you use actual data (steam tables) and when you assume ideal gas. Reference means H = 0. State all reasonable assumptions. Vapor-liquid phase partitioning is involved.
Make a list of the risks to society from the use of each type of power plant. With this knowledge, which type of radioactive decay has the net effect of changing a neutron into a proton? Which type of decay has the net effect of turning a proton i..

Assume that losses cannot be offset against revenues from other operations for tax purposes (i.e., no tax credits in years when the plant makes a loss). Estimate the following:
Combustion of Ethane: Stack Gas Molar Composition, Ethane is burned with 50% excess air. The percentage conversion of ethane is 90%. Of the ethane burned, 25% reacts to form CO and the balance reacts to form carbon dioxide
1a / state the formula giving flowrate (qv) in terms of valve flow coefficient, pressure drop across the valve and relative density of fluid. State the units of the variables in the formula.
