E. coli is cultivated in continuous culture under aerobic conditions with a glucose limitation. When the system is operated at D = 0.2 h-1, determine the effluent glucose (S) and biomass concentrations (X) by using the following equations (S0 = 5 g/L):a) Monod equation: 휇휇푚푚푚푚푚푚= 0.25 h-1, Ks = 100 mg/L, 푌푌푋푋/푆푆푀푀 = 0.4 g X/g S;b) Contois equation: 휇휇푚푚푚푚푚푚= 0.25 h-1, 퐾퐾푠푠푚푚 = 0.04, 푌푌푋푋/푆푆푀푀= 0.4 g X/g SCompare and comment on the results. Why might they be different? [Hint: consider the different assumptions under which each equation operates]

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

At a certain temperature the rate of this reaction is first order in hi with a rate constant of : 0.0632s2hig=h2g+i2g suppose a vessel contains hi at a concentration of 1.28m . calculate how long it takes for the concentration of hi to decrease to 17.0% of its initial value. you may assume no other reaction is important. round your answer to 2 significant digits.
