Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these

Chemical and Physical Processes of Digestion exercise T 8 he digestive system is a physiological marvel‚ composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need‚ and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract‚ it is progressively broken down

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

Lab 1 – Ubiquity of Microbes Bacteria are the most widely distributed organisms in the biosphere. They are found in all different types of soil‚ water and even in the bodies of other living organisms. Every single place that humans have explored on the Earth‚ have shown to contain microbes. Bacteria are living organisms and like all living organisms‚ they require energy and carbon sources in order to metabolize and reproduce. And like all living organisms they respond to changes in their environment
