Acid Rain and Buffers In the Midwest, the natural geologic formations are typically made of limestone (CaCO3). The limestone in the Midwest provides the lakes and soils with a natural buffer. The questions below highlight the benefits of natural buffers, or buffers in general. Pure Water 7. What is the pH of 1.000L of pure water? 8. If you add strong acid to pure water, unbuffered water, what magnitude of pH change do you expect? (pH drops a little, a...

1. Lakes that have been acidified by acid rain can be neutralized by liming, the addition of limestone (CaCO3). How much limestone in kilograms is required to completely neutralize a 5.8×109 L lake with a pH of 5.7? Express your answer using one significant figure. 2. For each strong base solution, determine [OH−], [H3O+], pH, and pOH. 0.0412 M Ba(OH)2 3.9×10−4 M KOH 2.5×10−4 M Ca(OH)2

6. Limestone can be considered to be essentially pure calcium carbonate. Acid rain can be considered to be sulfuric acid. When limestone buildings are eroded by acid rain the reaction can be summarized by the chemical equation below. CaCO+ HISO. Caso + CO. HO This reaction can be replicated in the lab by performing a titration a $6.93 g of Cacoa solid is added to 1.0 L of 0.235 mol/L sulfuric acid, how...

Limestone is predominantly, CaCO3, which can undergo the reaction. CaCO3(s) ===> CaO(s) + CO2 (g). We know from experience that this reaction is not spontaneous, yet ∆S for the reaction is positive. How can the second law of thermodynamics explain that this reaction is not spontaneous?

Conceptually, enterprise systems integrate the business process functionality and information from all of an organization's functional areas, making possible the coordinated operation of the functional areas and providing a central information resource for the organization. What do we call an actual implementation of the enterprise system concept through the use of integrated software packages designed to provide complete integration of an organization's business information processing systems and all related data?
