Write a balanced equation for the combination reaction described, using the smallest possible integer coefficients. Omit states of matter. When zinc oxide combines with water, zinc hydroxide is formed. (Use the lowest possible coefficients. Omit states of matter.)

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.
