    The spring constant Manuel Cereijido Fernández – UO237242 PL-4 -----------------------------------------------------------------------------------1. Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will

    Starting with the weight of .198 g of salicylic acid‚ the moles of the reactant was determined to be 1.43 x 10-3‚ as shown in Equation 3. The purified aspirin product was a white powder that had a weight of .140 g. The number of moles of the purified aspirin product after extraction was 7.77 x 10-4 as shown in Equation 4. These two moles calculated a chemical yield of 54.3% as shown in Equation 5. The melting point of the pure aspirin product was ranged at 117.8-125.2C as shown in Table 1.

    Name Period Date The Synthesis of Aspirin Background Pharmaceutical research labs perform chemical reactions between organic molecules that contain mostly carbon. Since the atoms in organic molecules tend to be nonmetals‚ then the bonds that hold them together are covalent bonds. Only a few elements on the periodic table are nonmetals: C‚ N‚ O‚ S‚ Cl‚ and F. This small number of elements can be bonded together in different quantities‚ bonding types (single‚ double‚ triple bonds)‚ and structural

    Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol

    Determination In “The Glass Castle” we see many different possibilities pertaining to Maslow’s Hierarchy of Needs. We see the father‚ Rex and one of the daughters‚ Maureen‚ who fall victim to Maslow. Then there’s Jeanette and the mother‚ Rose Mary who have both seemed to achieve self-actualization regardless of their hardships. Traditionally‚ Maslow’s Hierarchy is thought to be achieved by working up from the bottom of the pyramid to get to the top. However‚ in “The Glass Castle” this is not particularly

    If someone was assigned to compile a video of clips that would make me cringe‚ they would come up with something similar to The Purity Myth. The clips used were reminders of the oppressive‚ heteronormative‚ misogynistic system that I grew up in. The film itself provides ample examples of the ways in which women’s sexualities are policed‚ the idealization of virginity‚ the shortcomings of abstinence only sex education‚ and the arguments against women’s reproductive health. I have never been envious
