Which of the following statements about oxidizing acids is false? Select all that apply. In oxidizing acids, H+ is reduced in its reactions with metals. Most strong acids are oxidizing acids. H2SO4 can behave as either an oxidizing or non oxidizing acid depending on the solution conditions. The anions of oxidizing acids are reduced in their reactions with metals.

Use Scenario 8.3 to answer the following question.The calculated mass of sodium bicarbonate in the antacid tablet is:

The acid H2CO3 decomposes to some extent in water to produce CO2  gas. What should you expect to observe when the ingredients in an antacid react with HCl to produce H2CO3?

In sediments and waterlogged soil, dissolved O2 concentrations are so low that the microorganisms living there must rely on other sources of oxygen for respiration. Some bacteria can extract the oxygen in sulfate ions, reducing the sulfur in them to hydrogen sulfide gas and giving the sediments or soil a distinctive rotten-egg odor.Write the net ionic equation for the reaction under acidic conditions (H3O+) that releases O2 from sulfate and forms hydrogen sulfide gas. Use water as the reactant in the half-reaction that describes the formation of oxygen.
