(Select all that apply.) None of these Correct Answer Increase temperature at constant pressure. Correct! Add liquid water. Decrease in partial pressure of H2(g). Decrease container volume at constant temperature. Adding the strong acid, HNO3. (Consider any change in solution volume is negligible.) Removing some solid zinc. Adding the soluble salt, magnesium nitrate, Zn(NO3)2. Adding the soluble salt, sodium sulfide, Na2S.Summarize the significance of the Griffith and Averyexperiments.Consider the following reaction at 25°C with the ΔG°’ = +1800 J/mol for the forward reaction.The molar concentrations at the beginning of the reaction were [A] = 19 mM and [B] = 10 mM.After 1 hour, the concentrations were [A] = 16 mM and [B] = 13 mM.

- A 50-year-old man came to the emergency department after returning from foreign travel. His symptoms included persistent diarrhea (over the past 3 days) and rapid respiration (tachypnea). Blood gases were drawn with the following results: pH 7.21 pco2 19 mm Hg po2 96 mm Hg HCO3 − 7 mmol/L SO2 96% (calculated) (reference range, >95%) Question: What is the patient’s acid–base status? Why is the HCO3 − level so low? Why does the patient have rapid respiration?The amino acid alanine has two isomers, α-alanine and β-alanine. When equal masses of these two compounds are dissolved in equal amounts of a solvent, the solution of α-alanine freezes at the lowest temperature. Which form, α-alanine or β-alanine, has the larger equilibrium constant for ionization (HX ⇌ H+ + X−) ?Each of the following statements briefly describes one of Hb an allosteric interactions. Which of the statements below are false? A drop in the [H+] of blood plasma would lead to a decrease Hb affinity for O₂. An increase in the partial pressure of CO₂ in the tissues would lead to a decrease Hb affinity for O₂- If you inhaled CO for an extended period of time, at partial pressures 1000 fold higher than normal indoor atmospheric pressure, your body would have a difficult time delivering oxygen to your tissues. When the partial pressure of oxygen is low within the atmosphere, your body responds by increasing the biological activity of Hb's negative effectors.
