Consider the reaction: 2NO(g) + O2(g) + 2NO2(g)
Given an initial mass of 16.07 g NO, an excess of Oz, and assuming that all of the reactant is converted to product(s), and none is lost, calculate the mass (g) of NO2 produced
by the reaction.

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.
