(4) (22 pts) Gold metal dissolves in aqua regia, which is a mixture of concentrated hydrochloric and concentrated nitric acids, but gold does not dissolve in either acid separately. (You may write net ionic equations in this problem.) (a) (6 pts) Write a balanced chemical equation for the reaction of gold and nitric acid to produce Au(aq) and nitric oxide. Calculate the standard emf (in V) for this reaction. Is this reaction spontaneous under standard conditions at 25°C? (b) (6...

instructions 1 pts Question 4 Concentrated sulfuric acid is 18.1 M. The first hydrogen is a strong acid and is completely ionized, the second hydrogen is a weak acid with a K 2 = 0.012 If only the first hydrogen ionized the pH would be pH = -log(18.1) = -1.258. When we include the partial ionization of the second hydrogen, what is the pH of this solution? • Previous MacBook |

Question 5 (4 points) Definitely don't get this in your eyes! H2SO4 is a strong acid while H, PO, is a weak acid. Which of the following reasons correctly explains why that's true? There are between 1 and 4 correct answers. la H2SO, is a stronger acid than H3PO4 because H,SOhas fewer protons to lose. H2SO, is a stronger acid than H, PO, because the conjugate base, HSOA. is less stable than the conjugate base, H PO H,SOis a stronger...
