Is rusting a moderate reaction? Rusting is an example of what reaction?
A 100-liter fed-batch fermenter was successfully operated for 200 h using an aeration rate of 14 l/s and a 5 W agitator. It is proposed to scale the fermentation up to 10,000 liters. What agitator power consumption is required?
Assuming that there are no other significant side reactions, calculate masses of alcohol and ether produced, per 1000 kg of allyl chloride fed to the reactor.
Tris (pentafluorophenyl) borane, commonly known by its acronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound.
If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Represent this change using symbols for the elements, and write out the balanced equation.
Assume that an ordinary mercury-in-glass thermometer follows first order dynamics with atime constant of 10s. It is at a steady state temperature of 0°C. At time t = 0, the ther mometeris suddenly immersed in a constant temperature bath at 100°C.
question 1a with the help of a labeled drawing discriminate between the first-stage biochemical oxygen demand bod and
Find the minimum utility requirements for this process, for a minimum approach temperature of 10 °C.
at atmospheric pressure ethyl acetate and ethyl alcohol form an azeotropic mixture containing 53.9 mole of ethyl
Construct a table that summarizes the Level 0 information that you have, and information that you might need to obtain. Comment on choices that might need to be reconsidered and why. Comment on what you will do about currently missing information.
Why is it important - where does galvanising fit into possible corrosion protection strategies?)
where and Qp are constants for a given gas-polymer pair. Consider the diffusion of hydrogen through a poly (dimethyl siloxane) (PDMSO) sheet 20 mm thick.
The overall reaction in a commercial heat pack can be represented as: 4Fe(s)+ 3O2(g) yields 2Fe2O3(s); delta H=1652 kJ a. How much heat is released when 4.00 mol iron is reacted with excess O2?
