Calculate the ratio of H ions to OHâ€"" ions at a pH = 6. Find the concentration of H ions to OHâ€"" ions listed in Table B of your Student Guide. Then divide the H concentration by the OHâ€"" concentration. Record this calculated ratio in Table A of your Student Guide. Compare your approximated and calculated ratios of H ions to OHâ€"" ions at a pH = 6. Are they the same? Why or why not? Record your explanation in Table A. What is the concentration of H ions at a pH = 6? mol/L What is the concentration of OHâ€"" ions at a pH = 6? mol/L What is the ratio of H ions to OHâ€"" ions at a pH = 6? :1.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
