Explain why an oxidizing agent undergoes reduction.
Many important compounds in the chemical industry are derivatives of ethylene . Two of them are acrylonitrile and methyl methacrylate.
Complete the Lewis structures for these molecules, showing all lone pairs. Give approximate values for bond angles a through f, and give the hybridization of all carbon atoms. In acrylonitrile and methyl methacrylate indicate which atoms in each molecule must lie in the same plane. How many s bonds and how many p bonds are there in acrylonitrile and methyl methacrylate?
Physicians who specialize in sports medicine routinely treat athletes and dancers. Ethyl chloride, a local anesthetic commonly used for simple injuries, is the product of the combination of ethylene with hydrogen chloride:
If 0.100 kg of C2H4 and 0.100 kg of HCl react:
(a) How many molecules of gas (reactants plus products) are present when the reaction is complete?
(b) How many moles of gas are present when half the product forms?
Ammonia is produced by the millions of tons annually for use as a fertilizer. It is commonly made from N2 and H2 by the Haber process. Because the reaction reaches equilibrium before going completely to product, the stoichiometric amount of ammonia is not obtained. At a particular temperature and pressure, 10.0 g of H2 reacts with 20.0 g of N2 to form ammonia. When equilibrium is reached, 15.0 g of NH3 has formed.
(a) Calculate the percent yield.
(b) How many moles of N2 and H2 are present at equilibrium?
