Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics‚ both the thermodynamic system and its environment are considered. A thermodynamic system‚ in general‚ is defined by its volume‚ pressure‚ temperature‚ and chemical make-up. In general‚ the environment will contain heat sources with unlimited heat capacity allowing it to give and receive heat without changing its temperature. Whenever the conditions change‚ the thermodynamic

ACETANILIDE ABSTRACT Recrystallization is the primary method for purifying solid organic compounds through the differences in solubility at different temperatures. In this experiment‚ a suitable solvent was first determined. Acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The hot solution was filtered and the filtrate‚ cooled slowly in an ice bath as crystals started forming out. As the compound crystallizes from the solution

FUNDAMENTALs of thermodynamics (meg 210) INTRODUCTION TO THERMODYNAMICS Applied Thermodynamics is the Science of the inter-relationship between Heat‚ Work and Properties of Systems. It is concerned with the means necessary to convert heat energy from available sources such as chemical fuel or nuclear piles into mechanical work. Classical Thermodynamics This is the transformation of work and heat in relation to the properties of matter on macroscopic or bulk basis. Statistical

Introduction: Solubility equilibrium refers to the dissolution of a compound in water. Specifically‚ the degree to which a compound is soluble (Tro‚ 739). This can be measured using the expression Ksp = [Mb+]a[Xa-]b‚ in which Ksp represents the solubility product constant (Thorne‚ 90). This constant is important because it does not change at a given temperature‚ regardless of the solution a compound is in; a smaller constant would indicate lower overall solubility. It is important to note that

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations
