Un recipiente cerrado que contiene un gas ideal se reparte en dos volúmenes por un pistón móvil que no transmite calor (1 = 100 / , 2 = 200 /). La temperatura inicial en todo el recipiente es la misma (para los dos gases) y vale = 300 y la presión inicial también es la misma en todo el recipiente (para los dos gases) y vale 2 = 1,01 · 108 . Después, el gas de menor volumen se enfría hasta llegar a 1 = 273 , y el gas de mayor volumen se calienta hasta llegar a 2 = 373 . Suponiendo que la presión final de los dos gases es la misma, calculad esta presión.

Write a brief passage describing a neutral atom of nitrogen-14 (n-14). describe the number of protons, neutrons, and electrons in the atom, where each type of particle is located, and how the terms atomic number, mass number, and atomic mass are related to the particles. use the periodic table to you. 14 protons and eletrons since its a neutral atom

You have 125g of a certain seasoning and are told that it contains 76.0 g of salt what is the percentage of salt by mass in this seasoning

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
