surrounding the system * It takes energy to be organized lol * A cell is like an island of organization and it’s constantly fighting the sea of disorder to be organized. * Cells use energy from bonds of biomolecules (energy in bond is enthalpy) * Trade off is heat Table of approximate chem. Composition of e-coli shows that vast majority of energy goes into making macromolecules. * You can make polysaccharides from sugars * Fats/lipids/membrane from fatty acids * Proteins

Ice Calorimeter Determination with Mg June 18th 2013 Abstract: This experiment determines the amount of energy needed to melt ice. A spontaneous increase in enthalpy produce by combining 0.2036g Mg and 5.00mL H₂SO₄‚ ice was melted and readings were taken by using an ice calorimeter. Readings were taken before during and after the reaction were completed. The data taken shows a value of -405 KJ/mol while the theoretical value was -483.7 KJ/mol. Calculating the experimental

Alkali metals have largest size and lowest ionization enthalpy in their respective periods. Down the group‚ the size of alkali metals increases whereas ionization enthalpy decreases. 4. Alkali metals have low densities and densities increases from Li to Cs. (Exception: K is lighter than Na‚ due to bigger size of potassium atom). 5. Alkali metals have low

It will go into some of the branches and thoughts within these sub-theories; differential association theory‚ neutralization theory‚ techniques of neutralization‚ and social bond theory. It is also going to investigate how these theories try to explain the phenomenon of gang violence.

FUNDAMENTAL CONCEPTS Heat transfer is energy in transit‚ which occurs as a result of temperature gradient or difference. This temperature difference is thought of as a driving force that causes heat to flow.

The refining processes include 6 steps as; degumming‚ neutralization‚ dewaxing‚ winterization‚ whitening and deodorization. First step is degumming. Raw oil is hydrated then phospholipids‚ proteins and gums lose their solubility and they separate from oil. After that step‚

Introduction: The purpose of this experiment is to derive Isopentyl acetate (banana oil) from the reaction of an alcohol and a carboxylic acid in a process called Fischer esterification (Fischer-Speier esterification). The name‚ banana oil‚ is due to banana odour released by formation of Isopentyl acetate. The alcohol and the carboxylic acid used in this experiment are Isopentyl alcohol and Glacial Acetic Acid. Both the overall reaction of Fischer esterification and the specific Fischer esterification
