The principal source of sulfur on earth is deposits of free sulfur occurring mainly in volcanically Active regions. The offer was initially formed by the reaction between the two volcanic vapors S02 and H2S to form H2O(I) and S8(s). What volume of each gas, at 0.961 atm and 22°C, what is needed to form a sulfur deposit of 4.50×10 to the power of 5 kg On the slopes of a volcano in Hawaii?

Which statement about sound is not true? a. air particles travel with sound waves. b. sound waves cannot travel through a vacuum. c. sound waves exist even if no one hears them. d. air particles vibrate along the path of a sound wave.

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.

Describe the interaction that occurs between two objects with the same electrical charge.
