Examine the given line-angle structure and redraw it, correcting all errors of structure (bonding, lone pairs, formal charge, valence, and the octet rule). 14 H3C. CI- H3C CH3 O H3C B-CH3 N-CH3 CH3

Combustion requires three primary components: fuel, energy, and an oxidizer. The fuel is the organic starting material and once the activation energy is achieved, large amounts of energy are rapidly released fragmenting reactants into individual atoms. The components quickly rearrange into smaller and more stable molecules. Oxygen serves as an oxidizer, due to its electronegativity, accepting electrons and forming products including water and carbon dioxide.  Nitroguanidine (CH4N4O2) is used in select fertilizers and more commonly as a component to propel munitions. Suppose a field artillery soldier was calculating how much nitroguanidine was needed to propel a round. The soldier would need to consider the desired volume of gas to displace along the gun tube and the ambient operating conditions. a. Predict the reaction products for the detonation of 1 mole of nitroguanidine. b. Calculate the amount of explosive needed (in pounds) to produce 1500.0 liters of gas at standard temperature…

The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had (200. g) of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H₂2011. Calculate the maximum mass of water you could theoretically extract. Be sure your answer has alunit symbol, and round it to 3 significant digits. 0 HO CH₂OH OH OH OH The actual chemical structure of glucose.

5. Acetone and 2-propanol are chemically interconvertible. Reduction (by the addition of the equivalent of H2) of acetone yields 2-propanol. Conversely, oxidation (by the removal of the equivalent of H2) of 2-propanol yields acetone. Is the evaporation data for these substances the same or different? If different, can you account for why this may be the case from a comparison of the Lewis structures of each substance and the IMFs present in each substance? Explain.

Ethanol, C₂H60, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The combustion of one mole of ethanol releases 326.7 kcal of energy. The combustion of one mole of 2-methylheptane, C8H18, releases 1.306 × 10³ kcal of energy. How much energy is released during the complete combustion of 405 grams of 2- methylheptane? kcal Assuming the same efficiency, would 405 grams of ethanol provide more, less, or the same amount of energy as 405 grams of 2-methylheptane? more less the same amount Retry Entire Group 9 more group attempts remaining
