Uma indústria possui dois cilindros idênticos, os quais estão nas mesmas condições de temperatura (27ºC) e pressão (1atm) e contêm o mesmo volume de gases, sendo que um está preenchido com gás hélio e o outro com gás neônio, ambos puros. Considerando que o cilindro com gás hélio tem 1,6 gramas desse gás, pela hipótese de Avogadro, o cilindro do gás neônio deverá conter, em gramas massa de gás igual a:

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
