During a recent winter month in sheboygan, wisconsin, it was neccessary to obtain 3500 kwh of heat providd by a natural gas furnace with 98 % efficiency to keep a small house warm (the effiiency of a gas furnace is the percent of the heat produced by combution that is transferred into the house).
(b) how many gallons of lpg (liquefied petroleum gas) would be required to replace the natural gas used? assume the lpg is liquid propane [c3h8 : dnsity, 0.5318 g/ml; enthalpy of combustion, 2219 kj. mol for te formation of co2 and h2o and the furnace used to burn the lpg has the sam efficiency as the gas furnace .

Dying the folding patterns of protein molecules can microbiologists better understand cellular processes as well as some diseases, such as alzheimer’s, that are caused by proteins that have misfolded. the folding of these complicated molecules can be simulated on computers, but it takes a lot of processor power and time for even expensive supercomputers to do this. a group of researchers at stanford university developed software that can be used to distribute the processing of data to anyone who is willing to donate time on their idle personal computers. as a result, the researchers have been able to achieve protein-folding simulations that are far better than those other computing methods have done. which statement best describes the work of these researchers? the work is not scientific because the data are not processed in one location. the work is not scientific because the simulations are not reproducible. the researchers applied creativity to solve a problem in running an experiment. the researchers used only well-established scientific techniques.
