Experiment 14: Molar Mass of a Solid Angela Parra Laboratory Partner: Eugenia Jimenez Chemistry 1310 Instructor: Dr. Gao Laboratory Assistant: Lauren February 7‚ 2015 Abstract: The purpose of this experiment is to determine the molar mass of an unknown solid. The freezing point of a solvent (Cyclohexane) was determined‚ and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical

1972‚ Sweden’s National Board of Health and Welfare developed the idea of "basic foods" that were both cheap and nutritious‚ and "supplemental foods" that added nutrition missing from the basic foods. Anna Britt Agnsäter‚ head of the test kitchen at KF‚ a consumer co-op that worked with the Board‚ held a lecture the next year on how to illustrate these food groups. Attendee Fjalar Clemes suggested a triangle displaying basic foods at the base. Agnsäter developed the idea into the first food pyramid

NEWS LETTER FOGSI-LUPIN- Save the Girl Child Dear FOGSIANS‚ Greetings for the New Year. As the New Year dawns‚ our country stands poised to touch new heights on all fronts‚ but unfortunately the women of India still continue to suffer from "discrimination". The girl child is still underprivileged and neglected and unwanted. As professionals caring for the women only‚ we FOGSIANS also have a huge social responsibility to change the Indian Scenario. If we are aiming to save our

What type of media is KF streptococcal and what is the mode of action (i.e. what are the principle ingredients and how exactly does it work). KF streptococcal is selective media because it contains chemicals that would suppress the growth of the undesirable bacteria (Lee et al.‚ 1981). The media contain partially digested proteins which

Abstract This paper will discuss the design of an FM receiver. It will begin with a brief historical backdrop of FM broadcasting and its use in society. It will continue by providing the necessary mathematical background of the modulation process. Furthermore‚ it will enumerate some of the advantages of FM over other forms of modulation‚ namely AM. Finally‚ the paper will discuss the design of a basic FM receiver as well as introduce some circuits and circuit components which the reader may

NIKE‚ INC.: COST OF CAPITAL Book value vs. Market value While calculating the Nike’s cost of capital using both the book value (Exhibit 1.1) and the market value (Exhibit 1.2)‚ I could notice the mistake Cohen made finding the equity value. Cohen used the book value to reflect equity value. Although the book value is an accepted measure to estimate the debt value‚ the equity’s book value is an inaccurate measure of the value perceived by the shareholders. Since Nike is a publicly traded company

Fermi wave number kF works as a magnetic shield where the field produced by a magnetic object placed above graphene is always screened by a constant factor on the other side of graphene. The object is repelled by a diamagnetic force from the graphene‚ as if there exists its mirror image with a reduced amplitude on the other side of graphene. The magnitude of the force is much greater than that of conventional two-dimensional system. The effect disappears with the increase of kF . Graphene‚ an

ABSTRACT The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials
