In the activity paper that was given‚ it dictated that during the yogurt making process‚ the bacteria underwent fermentation. “Fermentation is any process where microorganisms use an external food source for energy. This process is done in a fermenter‚ conditions are controlled by mixing‚ water jacket.” – URL: http://scienceaid.co.uk/biology/micro/fermentation.html Below is the Lab Report of the group for yogurt making activity.

Submitted: June 6‚ 2012 Name: 2968 Instructor: Reid A hydrate was given to our group and the identity of the hydrate was unknown. The lab workers were told to determine the identity of the unknown hydrate. The identity of the hydrate could be determined by calculating the hydrate’s percent of water. So the lab workers set out to determine the water percent of the unknown hydrate. The percent of any compound or element can be found by using a certain formula. This formula is: % of element = Mass

Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label. The unknown in this experiment is presumed to be something similar to acetaminophen‚ such as acetanilide

The book‚ “Adventures in the Unknown Interior of America” was translated and edited by Cyclone Covey in 1961. It is a semiofficial report (more like a personal diary) written by Alvar Nuñez Cabeza de Vaca to the King of Spain regarding the Narváez expedition. The original report by Cabeza de Vaca was titled‚ La Relación (1542) along with supplemental material called the Joint Report was used to describe the epic events that happened on the expedition. Cabeza de Vaca was born in 1490 in the town

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Lab‚ Week # 1 BALANCE LAB Introduction The purpose of this lab is to learn how to utilize two different balances to find the mass of different chemicals in the ChemLab program. A balance is an instrument used to determine the mass of a chemical. To accomplish this we use direct weighing and weighing by difference on both the centigram and electronic balances. Equipment 1 Centigram Balances 1 Electronic Balance 1 100ml Beakers 5 Copper Slugs 2 Unknown Weights (Label # 1‚ # 2)

Change in the color of litmus from purple to pink or pink-red throughout the tube. Upon further incubation a white ring of litmus forms at the bottom of the tube at the pink-red color is now present only at the top of the tube. Still further incubation leads to the formation of a rennet curd at the bottom of the
