VIBRATIONAL-ROTATIONAL SPECTRA OF HCl Physical Chemistry Laboratory II‚ CHEM 3155.001 April 20‚ 2012 Introduction and Objective The experimental objective of this lab was to collect an IR spectrum of gaseous HCl and from it the experimental rotational constant‚ B‚ and fundamental vibration frequency‚ v0‚ can be calculated(1). The concept of infrared spectroscopy deals with the infrared region of the electromagnetic spectrum. Molecules absorb at specific resonant frequencies that are characteristic

cathodic peak current reveals diffusion controlled reduction. Moreover‚ the electroactive area can be estimated by Randles- Sevcik equation [2] for the modified electrode. The diffusion coefficient of enzymatically oxidized dopamine was obtained from slope of the straight line obtained in the plot Ipc versus υ1/2 (Fig. 4.3.4.1b). The electroactive area of the prepared electrode is calculated by equation [2] and it is 0.0396

Chemistry 1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical

equation f(x)=ax+b‚ where a is the slope and b is the y-intercept. Linear functions form a straight line when graphed and maintain a constant slope. It can be an increasing or decreasing function. For example‚ a lemonade stand sells a cup of lemonade for twenty-five cents. Graphed‚ x would be the cups sold‚ and y would be income. If the people running the stand start with no money‚ then the y-intercept will be zero. Because each cup cost twenty-five cents‚ the slope is twenty-five. The situation can

Calculation of compound lenses of A and B The relationship of the focal length is given by equation 5 and using the focal length found in Part I Rearranging the formula and isolating for fc: fc = (f1f2)/(f1 + f2) (equation 7) fc = (11.1cm*11.6cm)/(11.1cm + 11.6cm) fc = 5.67cm The theoretical focal length for the converging lens A and B was 5.67cm. %difference between the theoretical value and experiment

the period of the regression? The intercept is 0.0113. Since I calculate the excess return of Boeing and S&P 500 (the return of Boeing minus Rf‚ the return of S&P500 minus Rf)‚ I compare the intercept with 0. The intercept suggest that Boeing’s stock performed 1.13% better than expected. What is the slope of the regression? -What does it tell you about the risk of the stock? The slope of the regression is beta. Beta is a measure of the systematic risk. The slope is greater than 1. When the market
