Question

Write and balance the symbolic equations. Solve the problem completely on the reverse side of this page in a logical, neat, and orderly manner. Make sure to show all formulas, all substitutions, calculations and answers with appropriate labels. This equation set will be graded as a magnesium hydroxide reacts with sulfuric acid calcium reacts with water sodium sulfate reacts with ammonium chloride propane (C3H ) bums in air in your grill Do the following question on the REVERSE side of this page. Determine the pH of a 0.045 M NaOH solution. Determine the pH, pOH, and [H3O+] of a 0.073 M solution of HNO3. Complete the two reactions and indicate acid, base, conjugate add and conjugate base: HNO2(aq) + H2O rightarrow NH2 + (aq) + H2O+(aq) rightarrow

Explanation / Answer

Solutions are gien below,

1. 5Mg(OH)2 + 10H2SO4 ------------> 10MgSO4 + H2O

2. Ca + 2H2O ----------------> Ca(OH)2 + H2

3. No reaction

4. 2C6H6 + 9O2 --------------> 6CO2 + 6H2O [assuming O2 is the oxidant in air]

5. pH = 12.65

6. pH = 1.1, pOH = 12.9, [H3O+] = 0.073

7. HNO2(aq) + H2O(l) -------------> NO2-(aq) + H3O+(aq)

wherein, NO2- is the conjugate base of acid HNO2, and H3O+ is the conjugate acid of base H2O

8. NH2-(aq) + H3O+(aq) -------------> NH3(g) + H2O(l) [please note NH2- not NH2+]

wherein, NH2- is the conjugate acid of base NH3 and H3O+ is the conjugate base of acid H2O.
