2 1. Given the following graph – The vertices are the small circles and the edges are the linesconnecting them.A set of vertices is said to be independent if no two vertices in the set are connected by an edge.The independence number of a graph is the number of elements of the largest independent set.Independence numbers have applications in chemistry – if you think of the atoms of a moleculeas the vertices and the bonds as edges, independence number is connected to the chemicalstability of the molecule. Find the independence number of this graph. (Find the largestindependent set you can and circle those vertices)

Sugar is an organic molecule. Most organic molecules are non-polar compounds making them insoluble in water. However, this is not the case for sugar. Is sugar polar or non-polar? 1. Explain in terms of its molecular structure by researching/googling it. 2. Provide the link address. 3. How do you know that the source of information is valid? 4. What are the dangers of believing right away in an information which the author is unknown?
Like oxygen sulfur forms to covalent bonds. However sulfur is far less electronegative. In fact it has approximately the same electronegativity value as carbon. Based on your knowledge explain how the properties of various classes of biological molecules would be altered if you were to replace all of the oxygen atoms with sulfur.
2.3 INSTRUCTIONS: - Do not copy answers from Google or Bartleby. A plagiarism checker will be used. - Answer all questions as because they are connected. QUESTION: Why are fats and waxes solid at room temperature, whereas oils are liquids? EXPLAIN. With your answer to that question in mind, how do you think the phospholipids of coldwater fish compare to warm water fish? EXPLAIN.

Three pigment solutions are given to you. The first pigment, A, contains four -OH and two -NH groups. The second pigment, B, has two-OH groups. The third pigment, C, has a very long hydrocarbon chain with no oxygen. You are told to separate these pigments by paper chromatography using a solvent composed of 70% benzene and 30% acetone. Predict the locations of the three pigments on the paper with respect to the solvent front after they separate. Explain your answer.
Remember the glass slide experiment where two dry slides wouldn't stick to each other but the slides with one drop of water between them would adhere to one another? Ethanol forms fewer hydrogen bonds than water due to the chemical differences between the two molecules. If we performed this same experiment with the glass slides using ethanol instead of water, what would we observe? O It will be more difficult to separate slides with a drop of ethanol between them There will be no difference in the amount of effort required to separate slides with drops of ethanol or water between them O It would be easier to separate slides with a drop of ethanol between them
Match each molecule with its definition. Each definition may only be used once, but not all definitions will be used
In chemistry, "alcohol" is a word used for a general classification of molecules. The simplest one -- methanol -- is the 1-carbon alcohol; it's quite poisonous (ingestion causes blindness!) but because it dissolves bug splat well its most common consumer use is windshield cleaner. The 2-carbon alcohol is ethanol, it's not poisonous and most common, it's the alcohol in wine, beer, and liquor. Anti- freeze used in cars (shown below) is toxic, it's made of a different 2-carbon alcohol called ethylene glycol. The most common 3-carbon alcohol is isopropanol; it's widely sold in stores under a different name, it's widely used in homes, but it's toxic and not for drinking! What is this common household name of isopropanol? 2 words. [Google "household name isopropanol"]
