    Acid rain is a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen

    Purpose This experiment deals with separating substances. The objective was to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is

    Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic

    Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

    Identification of a Copper Compound by Percent Mass Unknown Compound: #9 Abstract: The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this‚ the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular

    then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but only half of that can be isolated as acetyleugenol. Clove oil contains two basic compounds: eugenol and acetyleugenol. As a result of Dalton’s Law and Raoult’s
