Which statement describes how no2- reacts in this equilibrium: h2so3(aq) + no2-(aq) hso3-(aq) + hno2(aq) as a brønsted-lowry acid by donating a proton as a brønsted-lowry base by accepting a proton as a brønsted-lowry acid by accepting a proton as a brønsted-lowry base by donating a proton

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.
