Write a balanced equation describing the reduction of H2SeO4 by SO2 to produce selenium.
Answer to relevant QuestionsWhat is the valence electron configuration of the halogens? Why do the boiling points and melting points of the halogens increase steadily from F2 to I2? What is a disproportionation reaction? Use the following reduction potentials ClO3- + 3H+ + 2e- → HClO2 + H2O ϐo = 1.21 V HClO2 + 2H+ + 2e- → HClO + H2O ϐo = 1.65 V To predict whether HClO2 will disproportionate. There is evidence that radon reacts with fluorine to form compounds similar to those formed by xenon and fluorine. Predict the formulas of these RnFx compounds. Why is the chemistry of radon difficult to study? How could you determine experimentally whether the compound Ga2Cl4 contains two gallium(II) ions or one gallium(I) ion and one gallium(III) ion? Phosphate buffers are important in regulating the pH of intracellular fluids. If the concentration ratio of H2PO4- to HPO42- in a sample of intracellular fluid is 1.1; 1, what is the pH of this sample of intracellular ...
