Determine whether each of the following compounds would be best represented by an ionic or a covalent Lewis structure.
MgCl2K2SBrClSF6
Draw the principal organic product expected when 2-methylthiophene reacts with HNO3. Show minimized formal charges, if applicable.
25.0 mL of a calcium chloride solution is added to an excess of aqueous silver nitrate. The resulting precipitate has a mass of 1.25 grams. If the percent yield of this reaction is known to be 85%, calculate the concentration in molarity of the or..
Some enzymes are produced as zymogens because a) the reactions they catalyze are undesirable at the site of production
Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl2 gas is 8.80 L at 885 torr and 25*C.
Activating effects question: Using resonance contributors, explain why the nitrile group is a deactivator and a meta director in electrophilic aromatic substitution. A drawing would be helpful too.
When natural gas (mainly CH4) is burned with 10 percent excess air, in addition to the main gaseous products of CO2 and H2O, other gaseous products result in minor quantities. The Environmental Protection Agency (EPA) lists the following data: Emi..
What will be the concentration of Ca2 (aq) when Ag2SO4(s) begins to precipitate. What percentage of the Ca2 (aq) can be separated from the Ag (aq) by selective precipitation
write structural formulas for the following condensed structures and determine the functional group in each compound.
Write the net ionic equation for the neutralization of the bases, magnesium hydroxide, Mg(OH)2 and aluminum hydroxide, Al(OH)3, found in Maalox, for example, with acid (H+).
Technetium-99 is a long-live radioactive isotope of technetium. Each nucleus decays by emitting one beta particle. What is the product nucleus?
Gaseous oxides of nitrogen rarely occur as pure substanced, but as equilibrium mixtures of them. One of these equilibrium mixtures is nitrogen dioxide and dinitrogen tetroxide.
Ozonolysis of a single enantiomer of R produces S, an acyclic, optically active ketoaldehyde of formula C6H10O2. Propose a structure for compounds Q,R, and S and show how your structures would react appropriately to give these results.
