Bio 120 Date 2-24-14 Scientific Method Lab Objective – For this lab, our objective was to identify the five mystery powders given to us which we were similar in appearance and to check their solubility and reactivity with water, vinegar and iodine. The objective was also to record information as accurate as possible and also to make observations in the reactions of five mystery powders with water, vinegar and iodine. Hypothesis- if we are using all the household mystery powders them they should

Acid-base disturbances The Acid Base Imbalance Regulation of hydrogen ion concentration in the body is a necessity for normal body functions.1 H + concentration in all body fluids are maintained to maintain pH ranges within narrow limits, this service is known as the balance acid-base (AB) 2.Arterial blood pH is maintained between 7.35-7.45, venous blood remains near 7,352. Most diseases / conditions disrupt AB, AB changes may be more harmful than the initial pathology. When AB is affected, causing

The Chemistry behind a Cheeseburger The first cheeseburger was created between 1924 and 1926 by a 16 year old chef from Pasadena, California named Lionel Sternberger. The anecdote goes that a passing homeless man suggested Sternberger should add a slice of cheese to his hamburger order. Sternberger then added this to his main menu at the Rite Spot and the cheeseburger was born.1 Today the cheeseburger is marketed by not only fast food chains like Steak-N-Shake and McDonald’s but also steakhouses

Titration in this lab is performed with the chemical reactions between acids and liquids. During titration, we have to stop at the point where stoichiometric amounts of acids and bases are reacting. We can find that point by looking for indicators, for example in this lab the indicators were changes in color. So the purpose of all this is to determine the concentration of some acid solutions. 1. Measure 10 mL of your acid solution using graduated cylinder and and it to the Erlenmeyer flask

Fish oil shows up as an alternative for the recovery of waste from processing of tilapia as a way of adding value to this raw material for biodiesel production. Thus, this study aimed to evaluate the yield and acid number of tilapia oil according to the type of waste used as well as to estimate its potential for biodiesel production as a function of the oil obtained. The waste consisted of fish viscera, fins, heads, skin, scales and mix of all residues mentioned. Such residues were provided by COPACOL’s

of matter. They thought that it was possible that individual particles made up matter. As you might imagine, it's useful to be able to measure the acidity of solutions. Scientists have come up with the pH scale for determining the concentration of acid in a solution so we can distinguish between solutions with varying acidity. A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together
