We have a mixture consistingof 90 mole% 'A' (45 mol/lit) and 10 mole%impurity 'B'(5 mol/lit). To be satisfactory quality the ratio of 'A' to 'B' in the mixture must be 100 to 1or higher. 'D' reacts with both 'A' and 'B' as follows;A + D?R-rA= 21 CACDB + D?S-rB= 147 CBCDAssuming that the reaction go to completion, how much 'D' need be added to a batch of mixture to bring about the desired quality
What is annihilation in terms of nuclear processes? Also, what are transuranium elements and how are they synthesized? Scientists have estimated that the earth's crust was formed 4.3 billion years ago.
Identify the ionic compounds in solution A and solution B. Identify the blood-red precipitate. Calculate the concentration (molarity) of all ions in the original solutions.
The standard enthalpy of formation of H2O(l) at 298 K is 285.8 kJ/mol. Calculate the change in internal energy for the following process at 298 K and 1 atm: H2O(l) yields H2(g)+12 O2(g);
Why fluids are important in chemical engineering - enormous number of materials normally exist as gases or liquids, or can be transformed into such phase and explain systematic description of change in fluid systems, mechanical change
1) Give a common everyday example of fluid dynamics.
Please answer these simple five questions on fabrication engineering at the micro and nanoscale.
Why does the dielectric constant of water drop as a function of temperature?
Mass of Compound Needed to Prepare 1 oz of a 10% Solution Hydroquinone, USP
Calculate the drum temperature, calculate the vapor and bottoms compositions and completely size the tower: Diameter, Height, weight.
Coal gasification is carried out at 850 °C and 40 atmospheres pressure, by reaction of coal with steam and oxygen. The empirical formula of the coal is roughly CH0.8S0.013. What materials of construction would you recommend for:
The enthalpy change of reaction for the balanced equation (with lowest whole-number coefficients) is H 67.7 kJ. If 2.50 102 mL of N2(g) at 100.C and 3.50 atm and 4.50 102 mL of O2(g) at 100.C and 3.50 atm are mixed, what amount of heat is..
