Energy and Waste

Do you believe that the government should establish a national energy policy? If so, how would you construct this policy? Would you emphasis non-renewable energy (oil, natural gas, coal) or renewable energy (solar, hydro, thermal)? If not, how would you address our current energy issues? Again, would you emphasis non-renewable energy (oil, natural gas, coal) or renewable energy (solar, hydro, geothermal)?

Your paper should be 2-3 pages in length and all citations must use APA formatting.

The National Institute for Occupational Safety and Health (NIOSH) sets standards for CCl4 in air at 12.6 mg/m^3 of air (a time average over 40 hr). The CCl4 found in a sample is 4800 ppb. Does the sample meet the NIOSH standard? INCLUDE THE PROCEDURE

Consider the following processes and determine if the entropy change of the system is positive, negative, zero, or you cannot tell. Explain. (a) Liquid water is frozen to form ice. (b) 1 mol of oxygen and 2 mol of hydrogen react isothermally and completely to form 1 mol of water vapor. (c) 1 mol of oxygen and 2 mol of hydrogen react adiabatically and completely to form 1 mol of water vapor.

In the procedure for the synthesis of hexaphenylbenzene, a Diels-alder reaction occurs and we needed to ensure all the starting materials were dry. After the reaction, we also washed with hexanes and toluene.
