9-19-13 Dehydrating and Rehydrating a Hydrate Introduction The mass percent of water was determined using the mass of water and dividing it by the total mass of the hydrate and then multiplying that answer by 100%. The number of moles of water in a hydrate was determined by taking the mass of the water released and dividing it by the molar mass of water. The number of moles of water and the number of moles of the hydrate was used to calculate the ratio of moles of water to moles of the sample

Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The

Atoms and Molecules lab summary In this lab the standard heat of combustion of magnesium was calculated by using the calorimeter. Also‚ the point of combustion of magnesium was to see how much heat would be released from fireworks such as sparklers. The concept of this lab was to find the difference in temperature from the beginning to end of combustion of magnesium and calculate the standard heat of combustion of magnesium by using the calorimeter and a thermometer. By using the thermometer‚ we

Interphase: DNA has formed already‚ but it remains in the simple form of chromatin. Chromatins are structures that are loosely coiled in the cell.3 I also observed during my lab that this was the only stage where I could still see a nucleus and nucleolus intact within the cell; this is because it’s the only stage where the nuclear membrane has

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it

Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

Halobacteria are also useful by being a good organism to perform DNA transcription‚ translation‚ and transformation on (Kramer‚ 2006). There are two different types of Halobacteria that are being observed in this lab. The first is NRC-1‚ which is also called the wild type strain. Although the pigmentation of the Halobacteria is caused by the production of the membrane protein‚ bacteriorhodopsin‚ which is a
