The scientific Method 1. Scientific Method- scientific investigation involving the observation of phenomena‚ the formulation of a hypothesis concerning the phenomena‚ experimentation to demonstrate the truth or falseness of the hypothesis‚ and result that validates or modify the hypothesis. Mechanist- Has belief that only natural forces govern living things‚ along with the rest of the universe. Vitalist- believes that the universe is at least partially governed by supernatural powers.

for two large‚ organic molecules: proteins and starches. Hypothesis: In the test for protiens the water‚ being that it is inorganic will not test positive for protiens; it will serve as the negative control. The milk and 50% egg solution should test positive for protien as they are subsatnce derived from animals which contain protiens in order to carry the functions of life. The sucrose will test negative due to the fact that it is a carbohydrate and not a composition of organic material but

expressed in ranges‚ am organic compound will have a sharp range depending on the purity of the compound. Impurity of an organic substance will register an abnormal melting point based on its expected propensity observed‚ this will cause the temperature range to widen. Using this hypothesis‚ mixed melting point technique could determine if the unknown compound added to the mixture causes a temperature depression‚ if not‚ the unknown is likely to be the same as your starting compound. Results: Melting

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface

"warm little pond" of organic chemicals that‚ over a long period of time‚ gave life to the first organisms. As this theory evolved‚ the pond became an ocean. In a breakthrough experiment conducted by Stanley Miller in 1953‚ the first reasonable experimental evidence for Darwin’s theory was developed. This evidence lay in a glass jar‚ in which a simplified version of earth in its infancy was created. Using water‚ ammonia‚ hydrogen and electrical discharge‚ Miller created organic chemicals‚ including

our air‚ water‚ and soil. Arsenic is usually combined with other elements‚ forming compounds with oxygen‚ chlorine‚ and sulfur; and it is in both organic and inorganic forms. Organic arsenic is combined with carbon and hydrogen‚ where inorganic binds with elements such as oxygen‚ chlorine and sulfur. Common inorganic compounds of arsenic are trivalent arsenic and pentavalent arsenic; and two reocurring organic compounds are monomethyl arsonic acid and roxarsone. Arsenic is released into the air by

to the origin of life‚ there is a schism over whether proteins of living cells or the genetic information was a precursor to the other. These debates have raised key questions over which conditions most favored the emergence of life. The myriad of organic life on the Earth may be derived from a number of sources: oceanic based genetic synthesis‚ volcanic-oceanic based metabolic synthesis‚ and interplanetary meteorites. Limitations of physical and experimental evidence has left this debate in much flux

PURPOSE To introduce two physical properties‚ the boiling point and the melting point‚ that organic chemists use to identify organic molecules. BACKGROUND/INTRODUCTION Organic chemistry is the branch of chemistry that deals with carbon containing molecules. Carbon can bond to other atoms forming multiple chains and rings‚ thus creating an unlimited number of organic compounds to exist. Each organic compound has many chemical and physical properties associated with its structure. In this experiment
