10. In an experiment, a sample was 90% decomposed in 24 min. Approximately how long would this decomposition have taken if the sample had been heated 20°C higher? (Hint: Assume the rate doubles for each 10°C rise in temperature.)

11. Find which kind of catalyst is necessary to facilitate the reaction between molecular nitrogen and molecular hydrogen to make ammonia (several words description)

1000 mol/min of a mixture of 90 mol% air and 10 mol% HCl enters an absorber column and is contacted with a stream of pure water entering the column at the rate 300 moles/min. 90% of HCl in the feed gas is absorbed by water. The two exit streams are gas stream (air+HCl) and liquid stream (water+HCl), respectively. 1. Draw and label a flowchart. 2. Define a basis of calculation. 3. Carry out a degree of freedom analysis and determine...

You are given four samples (approximately 10% oil and 90% water) all of which have been processed to have an average fat droplet size of 1.57 microns in each. They were prepared in the following manner and have different rates of separation: Sample 1 was processed with a standard homogenizer at 2000 psi with a velocity of separation being .3 m/s Sample 2 was processed with a standard homogenizer at 2000 psi (1st stage) and 500 psi (2nd stage) with...

10) A random sample of 13 students were asked how long it took them to complete a certain exam. The mean length of time was 120.1 minutes, with a standard deviation of 84.0 minutes. Find the lower bound of the 90% confidence interval for the true mean length of time it would take for all students to complete the exam. Round to one decimal place (for example: 108.1). Write only a number as your answer. Do not write any units....

In an experiment, why would the concentration of a sample decrease when changing the wavelength for a spectrophotometer from 235 nm to 280 nm? This is just a general question, I would like to know why the absorbance peak would be higher at a wavelength of 235nm rather than at 280nm. Is this normal? or could it an experimetnal error?
