Taking chem class in summer term fast pace need help to pass.

I have posted these once before but, some of the material is different in my chem II book. The teacher will give us a mid-term and a final in class so, these take homes are a opportunity to get good scores to pass the class. If you accept this post would you please include equations and answers so I can practice setting up the equation and working back to the answer. Thank You. 1) Calculate the hydrogen ion concentration and the pH of the solution formed when 0.020 gram-formula weight of nitric acid is added to one liter of aqueous 0.20 M ammonia solution. Assume no significant volume change upon addition of the acid. 2) Calculate the molar concentration of acetic acid at equilibriu... click for more
