Carbonate

Each of the test tubes contained 1ml of oxygen after the sodium carbonate was placed in the test tube. Once the weekend was over and it was time to gather the results, it was discovered that the practical failed and only resulted in of range of errors. However, in theory what should happened, was that the photosynthetic…

6) The organic phase which is the top layer was poured into a beaker right after the lower layer was removed. 7) A teaspoon of potassium carbonate was used to dry the organic phase. 8) The dry organic phase without the potassium carbonate was poured into a 250ml round bottom flask and being distilled again by using the same setup shown in graph(B.1) 9) The solution was boiled until it left 2-3ml(accidentally, as the lab manual indicates…

Annual global carbon dioxide emissions increased by over 20% between 1997 and 2009 from approximately 24 billion tons to over 30 tons of carbon dioxide (CO2) per year (Friedlingstein et al., 2010). The implications of this are vast and are by no means limited to global warming. For many millions of year prior to industrialization, ocean pH levels remained stable; however, high levels of anthropogenic carbon emissions in the near 200 years since the industrial revolution, have caused fundamental…

then there can be an understanding of the difference between the solubility because each chemical compound have different solubility even if they look similar. Materials: Equipment Chemicals Test Tubes (4) Water (H2O) Test Tube Rack Calcium Carbonate (CaCO3) Scoopula Candle Wax (CnH2n+2) (Paraffin Wax) Beakers Sodium Chloride (NaCI) Safety Goggles Sucrose Procedure: All equipment and…

4 mol) and sodium carbonate (0.2 mol) using methyl orange as an indicator. 1. Introduction Fossil fuel is formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years. “As the mud sediment was buried by more sediment, it started to change into…

This means there is not enough carbonate or calcium carbonate which forms shells and skeletons dramatically decreasing the coral’s reproduction (3). This problem began with the start of the industrial revolution when increases in industrial and agricultural activities caused more carbon dioxide to…

The Pk value for this equilibrium system is 6.3. It is evident that the pH is dependent on the concentration of hydrogen carbonate ions (HCO3-) and the concentration of carbon dioxide (CO2) in the air above the pool. equation 7 For optimal buffering capacity the ph of the pool (recommended to be 7.2 – 7.8) should be kept within one pH of the Pk value of the buffering…

warm climate. The continents were oriented very differently, the east coast of North America faced the south. Activities such as transgression of the sea, and carbonate deposition went on during this time. Eroded sediments were carried off by rivers into the ocean. Sand and was deposited near shore, mud was deposited off shore, and carbonates were deposited far off shore in areas that received little or no clastic sediments. Not only…

addition, double displacement also occurs in the test tube C. The positive ions of magnesium sulfate and sodium carbonate exchange and form magnesium carbonate and sodium sulfate. I checked both sodium sulfate and magnesium carbonate’s solubility in the solubility tables, which shows that magnesium carbonate is insoluble in water and sodium sulfate is insoluble; so magnesium carbonate is the precipitate at the bottom of the test tube. As a result, the type of reaction in test tube C is double…

under supervision of Abstract: In order to determine the identity of the compound we performed many experiments with a solution of the compound. These experiments included testing for all of the following ions; ammonium, halide, sulfate, carbonate, nitrate, and acetate. After comparing the results of these experiments we determined that our compound contained a halide. By using the flame test with a Bunsen Burner we also determined that our compound had a red colored flame leading us…
