INVENTION OF THE STEAM ENGINE Mankind’s interrelation with manufacturing systems has a long history. Nowadays we see manufacturing systems and their applications as systems in which goods are produced and delivered to the suitable places where we can obtain them. We are conscious of the fact that everything we consume or obtain is produced at some facilities. We are also aware of the fact that many components involve at these processes such as laborers‚ capital‚ and machines. Nevertheless‚ majority

SIMPLE DISTILLATION OF VODKA (ANTONOV) Kristel Joy M. Tan‚ Joshua Michael L. Torres‚ Pauleen Anne S. Vanadero‚ Paulene Arielle P. Ynzon and Rachel Pauline E. Zaballero Group 10‚ 2D Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is the most common technique‚ it is a process wherein the liquid is separated from the solution by boiling the liquid solution and condensing the vapor in order to get the distillate. There are four kind of distillation: simple distillation

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides

Questions: 1. One mole of a compound A‚ with vapor pressure 400mmHg at 50oC‚ mixed with 3 moles of compound B‚ with vapor pressure 480mmHg at 50oC to form a homogeneous solution. What is the vapor pressure of mixture at 50oC? XA =moles of A\total No. of moles XA =1\4 XB=3\4 Ptotal=PAoXA+PBoXB =400*1\4 + 480*3\4 = 460mmHg 2. Why should a distilling flask be filled not less than 1\3 filled or more than 2\3 full? This is to allow the liquid being heated room to expand as it turns

FRACTIONAL DISTILLATION *Ibale‚ I.‚ Ibanez‚ E.‚ Jao‚ E.‚ Joson‚ E.‚ Juanico‚ R. 2D Pharmacy‚ Faculty of Pharmacy‚ University of Santo Tomas Abstract Distillation is a commonly used method for separating mixtures based on differences in the conditions required to change the phase of components of the mixture. The product obtained by distillation is called the distillate. Volatility is the property of changing readily from a solid or liquid to a vapor. There are two types of distillation‚ simple

FRACTIONAL DISTILLATION October 29‚ 2012 CHEM 210 ME01 INTRODUCTION The process of separating the components of a mixture by distillation into relatively pure fractions is referred to as fractional distillation. Simple distillation‚ a process with similar goals‚ is noted for being a satisfactory attempt at separating two components in an ideal mixture‚ but not as accurate as fractional distillation. To explore these statements further‚ there needs to be an in depth look at the theory that

Distillation Objective: To illustrate the use of distillation for separating a mixture of two volatile liquids with different boiling points. Background: Distillation consists of heating a liquid until it vaporizes‚ and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points‚ or that have one component that does not distill. There are many types of distillation‚ each of which has a distinct

Arranged a fractional distillation apparatus used a 100mL round-bottomed flask for the solution and used a 50mL round- bottomed flask cooled in ice an ice bath as the receiver of the reaction. The 65% sulfuric solution was prepared in a clean 125mL Erlenmeyer flask it contained 20.0 mL of deionized water and 20mL of concentrated sulfuric acid was added carefully with some swirling in between. The diluted acid was cooled with an ice water bath to 20-25ºC. to the cooled sulfuric acid cyclohexanol was
