solution. The total protein concentration is exhibited by a color change of the sample solution in proportion to protein concentration‚ which can then be measured using colorimetric techniques. It is named for the biochemist Oliver H. Lowry who developed the reagent in the 1940s. His 1951 paper describing the technique is the most-highly cited paper ever in the scientific literature‚ cited over 200‚000 times. The method combines the reactions of copper ions with the peptide bonds under alkaline conditions

Experimental Determination of the Formula of Magnesium Oxide. Introduction: Magnesium is a mental‚ it is known to react with oxygen. Magnesium reacts vigorously when heated in the presence of air‚ which is why we have chosen high heat in our method to facilitate combustion. This oxidation reaction produces magnesium oxide gaining oxygen from the air. When sharing of electrons occur a chemical bond is made and the atoms combine to form a molecule. So‚ the predicted molecular formula:

The Scientific Method This experiment was performed by using a systematic approach to identify six unknown substances. In the first half of the experiment six unknown substances were observed than measured by determining volume‚ mass and density. The second half of the experiment the unknown were placed in a test tube and tested for solubility. It was determined that the six tubes contained coffee‚ potting soil‚ brown sugar‚ baby powder‚ baking soda‚ and powdered sugar. By the use of the scientific

"The Scientific Method is the process by which scientists‚ collectively and over time‚ endeavor to construct an accurate representation of the world. The scientific method attempts to minimize the influence of bias or prejudice in the experimenter when testing a hypothesis or a theory". Funny thing about the scientific method‚ the more research I did from web site to web site it became apparent to me that there are many views to actually how many steps there are in the process. For the purpose
