The diagram shows a Zn/MnO2-KOH alkaline dry cell. In your response, do the following: label all parts. Label the cathode and the anode, including the charges on each. Show the flow of electrons. Explain how the cell works. Include the oxidation and reduction half-reactions in your explanation

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same

Great amounts of electromagnetic energy from our sun and other bodies in space travel through space. which is a logical conclusion about these electromagnetic waves? their energy must be very their frequency must be very low these waves can travel without a medium they only travel through a vacuum of space

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.
