It administers the programs leading to the degrees of Bachelor of Science in Engineering with a major in Aerospace Engineering and Bachelor of Science in Engineering with a major in Mechanical Engineering. Both curricula are based on four-year programs of preparation for productive engineering careers or further academic training. Mission The mission of the Mechanical and Aerospace Engineering Department is to educate and prepare students at both the undergraduate and graduate levels for leadership roles in the fields of Mechanical Engineering and Aerospace Engineering and to conduct research for the benefit of society.

Post Experiment Problems After you finish your experiment, see if you can answer these problems below. These problems are very similar to those that will be found on your exams, and are an indication of if you are understanding the material fully.

Make sure to read the questions carefully and think about your answers, as you may see similar problems later on hint hint! Question Set 1 This question set deals with the first part of this tutorial. The preparation and dilution of solutions.

You need to prepare mL of 0. Instead of using a volumetric flask, a student used a graduated cylinder to add mL of water to a beaker containing the solid. The resulting solution was too concentrated.

You need to prepare 25 ml of 0. How many mmol of perchlorate anions, ClO4 -are in the 25 ml, 0. You also need to prepare a 0.

How many mL of the 0. Only 50 mL of 0. What volume mL of 0. Question Set 2 This question set deals with the second part of this tutorial.

A Criss-Cross Metamaterial Based Electrically Small Antenna

The preparation and usage of absorbance spectra and calibration graphs, as well as the use of the Beer Lambert Law.

The graphs below show the absorption spectrum for a 0. At what wavelength was the calibration graph obtained? The absorbance of the diluted solution is 0. What is the molarity of the undiluted sample?

The graph below shows the absorption spectra for an indicator in acidic and basic solutions. What color is this indicator in acid and basic solution? Based on the above specta, which of the following statements are correct? In acidic solution, the absorption coefficient e increases as l increases from to mm.

An acidic solution of the indicator has an absorbance of 0. What is [indicator] in this solution?Equilibrium chemistry is concerned with systems in chemical ashio-midori.com unifying principle is that the free energy of a system at equilibrium is the minimum possible, so that the slope of the free energy with respect to the reaction coordinate is zero.

This principle, applied to mixtures at equilibrium provides a definition of an equilibrium constant. Type or paste a DOI name into the text box.

I don’t like that they give you the rate, but don’t say what substance it is the rate for. The rate of formation of the product is different than the rate of the disappearance of the reactant. Basics of QA Case 1: You are cooking dinner for some friends, and are making some sauce for spaghetti.

You season, taste, and repeat this procedure until you have the sauce just the way you want it. CHEMISTRY H. Identification of Unknowns - 2. (rev 4/10) Finish working on the first unknown if necessary and begin working on the second unknown.
