CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

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

Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)
