1. 2.848 mole of A (g) is placed in a 2.00 liter container at 600 °C. The equilibrium constant is 0.441. Find the concentrations of the reactant and both products once equilibrium has been reached. 2 A (g) B (g) + C (g) 2. At equilibrium, a 2.0 liter container was found to contain 0.40 moles of A, 0.40 moles of B, 0.80 moles of C and 0.80 mole of D. If 0.10 moles of C and 0.10 moles of D are added to this system, what will be the new equilibrium concentration of A? A + B C + D 3. Calculate the pH of a solution made by mixing 20.0 mL of a 0.100M methanoic acid (CHOOH) with 80.0 mL of a 0.85M sodium methanoate (CHOONa). Ka for methanoic acid 1.78 x 10-4. 4. Barium sulfate is often given for patients to ingest as an image enhancer for gastrointestinal x-rays. Soft tissue does not appear on standard x-rays without an image enhancer. Here is an example of a swallow study. The patient is consuming the BaSO, to highlight the safe swallowing and function of the epiglottis. The barium ion is toxic to humans. What about this reversible reaction makes this a safe practice?
