Please [H+] = 10^-2.1 moles/L; pH =what is the keq expression of the equation BaSO4 (s) ---> BaO (s) + SO3 (g)What does the value of Kw say about the extent to which water molecule react with themselves? a. Water molecules react with themselves at constant rate, never increasing or decreasing. b. When an acid is added to water, the value of Kw will decrease. c. Because the value of Kw is so small, the extent to which water ionizes is quite large. d. Because the value of Kw is so small, the extent to which water ionizes is quite small.
- 5.8 Sulfur dioxide gas will form when nitric acid is added to a. CaCO3b. CaSO3c. CaSO4d. NaOHe. Water1. When a weak acid or base is dissolved in water, the acid always releases the _____ ion and the base always releases the ____ ion, and the release of either ion is controlled by an ________ between the released ions and the molecule that released it. For example, HOOCCH3 (aq) <-----> H+(aq) + -OOCCH3 (aq) [The two-headed arrow means that the reaction is reversible.] 2. Now do a bit of research and find any biological process that uses an acid or base (i.e., digestion, enzymatic reactions) and share the chemical reaction that you find and the significance of the reaction in a brief statement. After you share the reaction and its brief description, determine if the base or acid is weak or not, based upon the knowledge of it being a reversible reaction or not. Share your conclusion with the class and provide enough information to allow others to make good comments on your discussion thread other than the common "I agree" or "This is interesting" statements.Which value of ΔG corresponds with Keq = 1? -1 kJ/mol +1 kJ/mol 0 kJ/mol
