Ethanolamine, CH_NO, is a clear, viscous, hygroscopic liquid with an ammonia-like odor. It is used to remove Co, and H2S from natural gas but it is also found in polishes, hair waving solutions, and in emulsifiers (often in pharmaceuticals). Overexposure to this compound can cause irritation to the eyes, skin and respiratory system as well as lethargy. If a 0.25M solution of this compound is found to be 1.125 % ionized, determine the Kb and the Ka for this substance.

Distillation is a technique that is to purify liquid compounds. Use theoretical data to explain how distillation is used to separate the target product in this reaction from any residual unreacted starting material in the reaction. [2 marks] With this reaction: 2-methyl-2 butanol to 2-chloro-2-methylbutane (b.2-85.5 degree C)
i would like help with this question In a test of a gender-selection technique, results consisted of 208 baby girls and 225 baby boys. Based on this result, what is the probability of a girl bom te couple using this technique? Does it appear that the technique is effective in increasing the likelihood that a baby will be a girl? The probability that a girl will be born using this technique is approximately (Type an integer or decimal rounded to...
** use your own words, don't copy and paste, don't use handwriting, please. i need your references URL Link please** What is Denormalization? Explain this technique and discuss the following: - The advantages and the disadvantage of using this technique in Database design. - Why, alternatively in some situations, we might use Materialized View instead of Denormailization? Provide an example to support your arguments.
novel particle size separation technique using two immiscibleliquids! it a topic for research so i need some help with report and how to write some background and literature review for this topic i.e. novel particle size separation technique in which i have to use two immiscible fluids!
Why do smaller firms use the payback capital budgeting technique?
In our class demo on polyurethane, I combined toluene diisocyanate and glycerol (see structures below), which undergo an addition polymerization reaction (the two monomers simply combine without the loss of any atoms). In this reaction, the isocyanate group of the toluene diisocyanate combines with an alcohol of the glycerol to form an ester-like bond. он a. Draw the product of this reaction. I was disappointed in class by the lack of a "wow-factor" in this demo so I added water....
The use of digital systems means that you may not need to use manual technique often or ever. But you may still need to know how to do it, just in case. In your first post describe a scenario where you would need to use a manual technique to obtain your image (trauma, surgical suite, non-routine due to patient condition, etc.). Be sure to include the following: Which body part is being imaged? How is the part and IR positioned?...
That's all the information. Something like this. Something like this. I don't know why you need more information. Its already plotted the (Enzyme) if i cant be answered close the question, so I may repost it again. Just asked the professor so i don't know. 6. The Michaelis-Menten curve for enzyme X is shown below for substrate A. Indicate where on the plot you would determine Keat, Kn and kca/Km. 500 1500 2000 1000 substrate A, UM We were unable...
