Rachel Smith Design Lab: Kinetics Lab Introduction: ! Background Information- Effervescent tablets reduce stomach acid and help treat upset stomachs. The familiar fizzing you hear when you drop an Alka-Seltzer tablet into a glass of water is the result of a chemical reaction. After dropping the tablet into the water‚ the reaction causes the solid tablet to become dissolved and releases tiny bubbles of carbon dioxide. This reduces the time it takes for the medicine to work as it does not need to dissolve

Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation

Introduction and Theory: A two dimensional object is a figure that has both width and height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know

Being able to extract a compound or substance from a product or object will encourage us in being able to do the same in a similar manner with a tea solution. Extracting compounds is an important step in any kind of organic chemistry lab and will help us be better at accomplishing the experiment in a much faster and accurate rate than from before. Experimental To begin the experiment‚ a tea solution must be made by incorporating a tea bag into a beaker filled with almost boiling water and the

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether
