A drug is introduced that alters blood pH. Predict how this change would affect enzyme function, oxygen binding by hemoglobin, and chemical equilibrium within the body. Then explain how changes at the molecular level—including bonding, concentration, energy transfer, and gas behavior—can lead to large-scale physiological effects in human systems.

Determine whether each molecule is paramagnetic or diamagnetic. Then explain how magnetic properties can influence behavior in biological and medical contexts. In your discussion, describe the relevance of paramagnetism to imaging techniques such as MRI and discuss how magnetic properties may affect molecular interactions in biological systems.

Assign formal charges where appropriate and identify any resonance structures. Then explain how resonance stabilization increases molecular stability. In your explanation, connect resonance to energy lowering, electron delocalization, and the structural flexibility of molecules.

Explain why real gases deviate from ideal gas behavior. For each cause, including intermolecular forces and molecular volume, describe how it affects pressure and volume predictions. In your discussion, explain the basic concept behind the Van der Waals correction.

Design an oral rehydration therapy (ORT) formula that includes appropriate solutes, such as Na⁺, Cl⁻, glucose, and any other relevant components. Specify the concentrations of each component and justify your design choices. In your discussion, explain how your formulation achieves electrolyte balance, promotes appropriate osmotic effects, and maximizes absorption efficiency. Finally, explain how solubility, electrolyte behavior, and colligative properties work together to determine whether a solution is safe and effective for medical use.

Using evidence from your previous answers, explain how bonding, molecular geometry, and polarity work together to determine whether a molecule functions primarily as a structural material, a conductive system, or a biologically active compound. Include specific examples to support your explanation.

Explain the difference between potential and kinetic energy, relating potential energy to chemical bonds and kinetic energy to molecular motion and heat, and explain why excess kinetic energy in the form of heat must be carefully regulated in the human body.

Explain how hemoglobin binds oxygen at the molecular level. In your discussion, describe the roles of molecular shape and intermolecular forces in oxygen binding. Then predict what may happen to oxygen transport if the structure of hemoglobin changes.

Apply the Bohr model to both hydrogen and hydrogen-like ions, explain how the model accounts for their spectral lines, and discuss why the Bohr model fails to accurately describe multi-electron atoms.
