Calculate the pH of 6.0 × 10-4 M NaNO2.
Answer to relevant QuestionsElements in the same family often form oxyanions of the same general formula. The anions are named in a similar fashion. What are the names of the oxyanions of selenium and tellurium: SeO2-, SeO32-, TeO42-, TeO32-? Reaction of 2.0 L of hydrogen gas with 1.0 L of oxygen gas yields 2.0 L of water vapor. All gases are at the same temperature and pressure. Show how these data support the idea that oxygen gas is a diatomic molecule. Must we ...Explain the law of conservation of mass, the law of definite proportion, and the law of multiple proportions. From the information in this chapter on the mass of the proton, the mass of the electron, and the sizes of the nucleus and the atom, calculate the densities of a hydrogen nucleus and a hydrogen atom. Calculate the resulting pH when 1.00 L of 1.00 M H2SO4 is added to a tank containing 1.00 × 107 L of pure water.
