Carbon disulfide gas and oxygen gas react to form sulfur dioxide gas and carbon dioxide gas. What volume of carbon dioxide would be produced by this reaction if 5.40 cm of oxygen were consumed? Also, be sure your answer has a unit symbol, and is rounded to 3 significant digits. 8 X 0 0. 0.2 5 0b A mixture of krypton and oxygen gas is expanded from a volume of 53.0 L to a volume of 84.0 L, while the pressure is held constant at 50.0 atm. Calculate the work done on the gas mixture. Round your answer to 3 significant digits, and be sure it has the correct sign (positive or negative).

1. Calculate the Coulombic (ionic) interaction energy between atoms for the C=O ∙∙∙H-N hydrogen bond in a peptide at a distance of 1.5Å in units of kJ/mol. Assume that the partial charge on O is −0.434, the partial charge on H is +0.417 and the permittivity of the protein environment is 6.  2. The dipole moment of an individual peptide group is approximately 3.46 D. Assuming that the dipoles line up linearly estimate the energy of interaction (in kJ.mol) of the hydrogen bond in Q1 using a dipole-dipole model.

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  300.g  of ordinary table sugar, which chemists call sucrose, and which has the chemical formula  C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.
