indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

with this optional observation lab was a great experience overall‚ just as I had expected it to be. I was much more interested in participating in the observations versus sitting in a classroom every week and attending the labs like in 1010. The first event that I attended was the courtyard telescope setup on January 31st‚ in which we were observing a couple of different provinces and sunspots located about 10 o’clock region located directly on the sun. (See lab book for illustration.) We were

colorless colonies. Multiple medical experiments are credited towards transformation‚ especially ones involving cancer and the transformation of normal cells to neoplastic and cancerous cells. Introduction The general purpose of the Transformation Lab was to observe the difference in bacterial growth under differing media conditions to help understand the process of transformation and how it contributes to the life of living organisms. "Transformation" is what occurs when a cell receives and expresses

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

In 1978‚ The Airline Deregulation Act was purposed and signed by President Jimmy Carter. This federal law came into existence for two main reasons; stated by Carter (1978)‚ “to help our fight against inflation‚ and to ensure American citizens of an opportunity for low-priced air transportation. Today’s motives in the airline industry go way beyond economic decisions for themselves as well as their shareholders. Nowadays‚ businesses are an essential part of society and the airline industry must

Short-Term Scheduling GLOBAL COMPANY PROFILE: Scheduling Airplanes When Weather Is the Enemy Throughout the ordeals of tornadoes‚ ice storms‚ and snowstorms‚ airlines across the globe struggle to cope with delays‚ cancellation‚ and furious passengers. Close to 10% of Delta Airline’s flights are disrupted in a typical year‚ half because of weather; the cost is the $440 million in lost revenue‚ overtime pay‚ and food and lodging vouchers. Now Delta is taking the sting out of the scheduling nightmares

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress
