    ¾ inch of the Copper(II)Carbonate was placed into a test tube. The test tube, by means of a clamp, was fastened to a ring standard to be heated by the Bunsen Burner. A one hole rubber stopper fitted with a glass tube was fitted into the top of the test tube. A measurement of 5 ml of the Limewater was placed into a graduated cylinder. With test tube holders, a separate test tube was held over the end of the glass tubing to collect the gas produced. The Copper(II)Carbonate was heated until it…

    percentage 85% to 90% of the organic portion is collagen. Both collagen and carbonate can be used to obtain the information for stable isotope analysis. There is a debate as to what is the better tissue for usage in stable isotope analysis, and it seems to be that carbonate is the better option of the two. Collagen degrades over time and is the carbon in collagen comes from the consumed carbohydrates and proteins. Carbonate, on the other hand, can be used for much older materials and the carbon…

    1.Soil forming factors 1) Climate- The climate of the Pullman series leans on the side of ustic and is in fact a Paleustoll, but can boarder on aridic at times. Ustic is an intermediate between udic and aridic with the winters being relatively dry, and the growing season is characterized by plant available moisture between significant periods of drought. The Pullman series meets this descriptions, in that it’s driest periods lie between July and August, and then December through February, with…

    compound, then the known anion is the anion of the unknown compound. For the carbonate test, 1mL of known compound containing carbonate was added to a test tube. 6M HCL was added very slowly to the test tube in order to detect any effervescence. The reaction resulted in effervescence, so carbonate is the anion. When the carbonate test was conducted with the unknown, no reaction occurred, leading to evidence of the absence of carbonate in the unknown. For the sulfate test, a few drops of Barium…

    The South Window of Canterbury Cathedral has long been one of the largest and eldest stained glass windows in existence. A factor that has had an impact on the ongoing restoration process is the high content of potassium oxide in the glass. Its presence renders the window more susceptible to the damages caused by pollutants. This study aims to analyze the making and restoration of the South Window of Canterbury Cathedral in relation to the potassium oxide that contributed to its deterioration.…

    Ocean acidification is detrimental to calcium carbonate life. As CO2 is absorbed into the ocean, it has a chemical reaction with water and forms carbonic acid, lowering the pH. This acid reacts with the calcium carbonate that many shellfish need to build their homes and protection, forming a different type of molecule, and depleting the ocean’s calcium carbonate resources. While it was obvious in our lab that our four mollusks, wrinkled drill, cowrie, small oyster, and large oyster, were to be…

    sulfuric acid is neutralised by sodium carbonate (as shown in equation 1) (Fischer esterification reaction), which is converted to soluble sodium sulfate, sodium ethanoate and carbon dioxide which is released by inverting the separating funnel, and opening the tap. Equation 1: Ethanoic Acid + Sodium Carbonate  Sodium Ethanoate + Carbon Dioxide + Water CH3COOH(aq) + Na2CO3(aq)  CH3COO-Na+(s) + CO2(g) + H2O(l) Equation 2: Sulfuric Acid + Sodium Carbonate  Sodium Sulfate + Carbon Dioxide +…
