Formamide decomposes at high temperature. if 0.186 mol of formamide (hconh2) dissociates in a 2.16 l flask at 400 k, what are the concentrations of all species present at equilibrium at 400 k? (hint: calculate concentrations first) (b) what is the total pressure in the container at equilibrium?

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.
