Use this balanced equation to answer questions 5 and 6. NaHCO3 + HCl→ NaCl + H2O +CO2. 5. Solve for the theoretical yield of NaCl (g NaCl). Use the mass-to-mass stoichiometric calculation. Start with 2 g NaHCO3. Show your work correctly. Label your numbers. Include the unit and formulas of the compounds. Circle or box your final answer.

If you add 5.00 ml of 0.100 m sodium hydroxide to 50.0 ml of acetate buffer that is 0.100 m in both acetic acid and sodium acetate, what is the ph of the resulting solution? acetic acid: ka = 1.8. x 10-5

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
