Atoms are the basic units of matter and all life is based on them. Life on earth is based on the element carbon. It is a highly versatile atom able to form four covalent bonds with itself or other atoms such as hydrogen and water. Atoms combine to form molecules and those that are carbon based are referred to as organic molecules. Organic molecules occur in four different types in living cells; carbohydrates, lipids, proteins and nucleic acids. They are also known as hydrocarbons due to the presence of both hydrogen and carbon. Carbohydrates are made up of carbon, hydrogen and oxygen in the ratio 1:2:1. They are important sources of energy and are classified in three main groups; monosaccharides, disaccharides and polysaccharides.

Abstract: One mixture of two unknown liquid compounds and one mixture of two unknown solid compounds were separated, isolated, purified, and characterized by boiling point. Two liquid unknowns were separated, isolated, and purified via simple distillation. Then, the process of an acid-base extraction and washing were used to separate two unknown compounds into two crude compounds: an organic acid and a neutral organic compound. Each crude compound was purified by recrystallization, resulting in a carboxylic acid (RCO2H) and a pure organic compound (RZ). The resulting mass of the pure carboxylic acid was 1.688g with a percent recovery of 31.80%, the boiling range was 244-245 °C, and its density was 2.0879g/mL. The resulting mass of the pure organic solid was 2.4902g with a percent recovery of 46.91%, the boiling range was 52.0-53.4°C, and its density was 1.5956 g/mL.

The proof (twice the % alcohol) starts at its maximum and goes down (as the alcohol evaporates). If we start with a high concentration of alcohol, we will get the azeotrope (95% alcohol, 5% water) for a while, then the concentration will decrease.

What is the percentage yield of the reaction of iron and copper chloride when steel wool and copper chloride dehydrate are used as reactions?

Purpose: To use indicators to test for the presence of organic compounds in certain substances.

1. Place a small amount of wax from a birthday candle into a test tube. Heat gently over a burner flame until the wax melts completely; then allow

5. Zoom Out by clicking on the green arrow next to the Save button. Click on the Stockroom and then on the Clipboard and select Balloon Experiment N2. Again, set the temperature, pressure, and moles to 298 K, 1.00 atm, and 0.300 moles, respectively. You may have to click on the Units button to change some of the variables to the correct units. Repeat the experiment with this gas labeling the data link ‘Real Gas N2.’

In experiment 3.11, we found out whether or not a larger amount of a liquid would get hotter when it boils. To answer this, we heated a specific amount of unknown liquid and recorded the temperature every fifteen seconds. In our scatter plot, we were able to find the boiling point of our liquid. We know that the slope of our graphs is when the liquid molecules were moving around and heating up. The plateau of our graph points is where the liquid started to evaporate and boil. This is were we found our boiling point at. Shantel and I decided that our boiling point was about 98º Celsius. If you had another slope in your graph, that was when you were simply heating the leftover gas. The histogram showed us that there were about equal amounts of data in the higher temperature (about 95º Celsius) bins for both 20mL of liquid and 10mL of liquid. Also, in the lower temperature bins (75º to 80º Celsius) there was about equal amount of data for 20mL of liquid and 10mL of liquid. There was 7 pieces of data for 10mL of liquid in the lower bins, and 6 pieces of data for 20mL of liquid. If a larger amount of liquid did have a higher boiling point, the clusters would be organized by volumes or amount. For example, all of the 20mL pieces of data would be in the higher temperature bins, and all of the 10mL pieces of data would be in the lower temperature bins or flipped. Rather, the bins were clustered by identity. The boiling point is a characteristic property.

Introduction During this unit, we learned about 5 types of chemical reactions. They consist of Synthesis, Decomposition, Single Displacement, Double Displacement, and Combustion. A synthesis reaction or direct combination reaction is one of the most common types of chemical reactions. In a synthesis reaction, two or more chemical species combine to form a more complex product. A + B → AB.

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

In 1994, GMO’s were originally introduced through a newly developed, slow ripening tomato. Calegene Inc. took it upon themselves to take “a specific DNA sequence” and “reverse [it] within the plant, which [retarded] the softening process.” Also known as the Flavr Savr TM, this new breed of produce can spend a longer amount of time on the wine in order to “fully develop its flavor”, and aids in reducing damages that might come with handling and shipping. In spite of this “miracle” tomato

Technology has been advancing at an increasingly high rate; as a result scientists have used this development to create genetically modified foods. Biotechnologies used to genetically modify foods have contributed to the controversial statements, whether or not genetically modified foods should be available for human consumption. Genetic Modified plants and foods such as the “Flavr Savr Tomato” enhanced through the use of biotechnologies have sparked arguments in favour and against. Those in favour consider that they are advantageous for humans, those against believe that it is detrimental for human consumption and altering the

Organic compounds are, by definition, any chemical compound containing carbon. These compounds include carbohydrates, polysaccharides, lipids, proteins, and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the fats of a cell. Proteins are the building blocks of muscle in a cell. Nucleic acids are used to transfer genetic information from one cell to the other.
