Alexis Becker Pre-Lab Experiment 7 Avinash Pallagani Investigating Stoichiometry with sodium salts of carbonic acid 4/2/14 A summary of the concepts: The purpose of this lab is to better understand “stoichiometry”. We will be reacting sodium carbonate (NaHCO)3 and sodium carbonate (Na2CO3) with hydrochloric acid to produce sodium chloride‚ water‚ and carbon dioxide. The balanced chemical reaction looks like this: NaHCO3 + HCl = NaCl + H2O + CO2 CAUTION: Be especially

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion is present in the K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O using

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

Biochemistry is the chemistry of biological systems. The practical component of biochemistry is aimed at developing your interest in and understanding modern biochemical and molecular biological experimentation. The techniques learnt in the biochemistry lab will be applicable to all life sciences. THE OBJECTIVES OF THE BIOCHEMISTRY LABORATORY INCLUDE: (1) Learning the theory behind the techniques and biochemical pathways (2) Learning the physical skills and techniques of modern experimental biochemistry

Joe Parise Coms 356 2/18/10 Static and Dynamic Composition In the film Turtles Can Fly we are introduced to a girl named Agrin. She is with a small child around the age of three named Riga. We see throughout the film that Agrin has a strange hatred for the child and wants to rid him from her life. As a viewer we are left to assume that the three-year –old Riga is Agrin’s son‚ a product of rape when her village was invaded. Ghobadi‚ the film’s director‚ uses one scene that really stood out
