Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

Between the hundreds of acres of corn that make up Iowa lies a speck of flickering lights named Mount Vernon. Built in the shadows of Cedar Rapids‚ Mount Vernon is not unlike any other small Iowa town hoisted up by farmers with corn sprouting up on every possible plot of land‚ housing developments appearing overnight to appease the rich businessman‚ and of course‚ the best high school in the state. However‚ Mount Vernon is not nearly as nice and quaint as it may seem. In this sleepy town time appears to

encoded by EZH2‚ the EZH2 gene encodes part of the Polycomb group which make protein complexes that help to maintain genes transcriptional repressive state over successive cell generations. http://www.ncbi.nlm.nih.gov/gene/2146 Throughout this lab report template DNA that contains the gene EZH2 was provided‚ this will be amplified by a PCR and cloned into a vector. This Polycomb group proteins help maintain the cell identity during progress through chromatin

The devastating avalanches on Mount Everest in 2014 and 2015‚ highlighted some longstanding problems for the climbing industries in Nepal. Especially for local Sherpa guides where issues like overcrowding‚ safety‚ meager wages and insurance are of immense concerns. These problems have left many wondering why the Nepal government hasn’t done more support the Sherpa guides? The group of people risks their lives so that foreign climbers can attempt Everest. The desire to conquer Everest has been on

separatory funnel to remove the water layer. 5mL of 10% K2CO3 was added to the extracted organic layer‚ and then placed into the separatory funnel for the removal of the water layer. NaCl was then again added to the organic layer‚ and put through the separatory funnel to again remove more of the water layer. After the water removal using the separatory funnel took place‚ MgSO4 was added until clumping subsided. This addition was done to remove any access water that the previous processes did

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda solution

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion
