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

I. Introduction Fractional distillation is the separation of a mixture into its fractional parts that entails many concurrent vaporization-condensation cycles. This works because of different boiling points of individual substances. The temperature of the fractional distillation column decreases as its length increases. A higher boiling point component condenses on the column and returns to the solution whereas the lower boiling point component passes through the column and is collected in a receiver

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

Cubism What is Cubism? Cubism is a revolution in the artist’s approach to space‚ both in the flat surface of the picture and in sculpture. In this essay the things that will be discussed are two different styles of Cubism‚ which are Analytic and Synthetic Cubism. Also the artists who invented Cubism and those artists are Pablo Picasso and Georges Braque. Analytic Cubism fragmented objects into abstract geometric forms. Good examples of Analytic Cubism are Braque’s‚ Violin and Picher and Picasso’s

f Fractional Distillation of a Solution Results 1. On a single graph‚ plot boiling point versus volume of distillate curves for the two distillations of the cyclohexane/toluene solutions (one from the simple distillation experiment and one from the fractional distillation experiment). The graph is to be computer generated and presentation quality (e.g.‚ appropriately scaled and labeled axes‚ descriptive title‚ and discernable data points). The data points are to be connected with a smooth

How Do Synthetic Drugs Affect China? Synthetic drugs are prevalent across China‚ affecting the country in countless ways. Drugs are created for medical uses to treat injuries or illnesses‚ however others are exploited due to the body’s reaction towards the drug such as narcotics. A simple definition of synthetic refers to “ manmade” (Van).The primary purpose of synthetic drugs is for medical or pharmaceutical uses. This means that it is intended to aid people who are recovering from ailments. For

Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

the artificial surfaces. Astroturf is a brand of artificial turf or synthetic grass was developed by the Monsanto Industries in the 1960’s. The Ford foundation was studying ways to improve the physical fitness of young people at the time. Monsanto’s Chemstrand division was urged by the Ford foundation to make the perfect sports surface for schools. In 1964 the Creative Products Group installed the first large-scale synthetic turf called Chemgrass at the Moses Brown School in Providence Rhode Island

Of late reports have been received that large quantities of such spurious and fatal product have found way in markets of Rajasthan‚ Himachal Pradesh‚ Uttar Pradesh‚ Bihar‚ Madhya Pradesh‚ Karnataka and Orissa. The monster is surfacing in Punjab and Haryana also. Chemicals like urea‚ caustic soda‚ refined oil (cheap cooking oil) and commonly used detergents are used in the preparation of synthetic milk.
