You are working in your laboratory and decide to do some cleaning. you find a test tube with some brown substance congealed at the bottom. you take a piece of iron wool to scrub it out, but cannot remove it. you leave the iron wool in the test tube and set it aside to clean your beakers instead. you do not realize the test tube is next to the heater and after a few minutes, a brown gas starts smoking out of the test tube, followed by a reddish-brown gas. upon observation, the iron wool is coated in a yellow-brown substance. you realize that the mystery substance was

Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydroxide.

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.

What layer of the atmosphere is directly above the troposphere?
