samples of NH3(g) and O2(g) are placed in a rigid container. When the equilibrium below is established, the partial pressure of H2O(g) is 0.784 atm. What is the partial pressure of NO(g) when the system is at equilibrium? 4 NH3(g) + 5 O2(g) 4 NO(g) + 6 H2O(g)

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.
