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

go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same

Lab Report Marisa McKinney P. 2 Purpose: To investigate the periodic variation of density in Group 4A elements. Background: When the elements are arranged in order of increasing atomic number‚ they exhibit periodic recurrence of properties. Elements in the same group in the periodic table tend to have similar physical and chemical properties. These similarities are due‚ in large part‚ to similarities among the electron configurations of the elements in a group. You can find periodic

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

Introduction Human cilia play a critical part in human processes. Human cilia are hair-like projections that extend from the surface of a cell. Cilia are capable of rhythmic motion and acts together from separate strands so that the cell is capable of movement. Flagella are a whip-like structure that is found in cells as well that allow for the movement of the cell. Human cilia are characterized as having “metachronal rhythm" and this means is a rhythm that "changes time" to produce wave. The beating
