General Chemistry 2 Final Exam Questions and Answers | Latest Version | 2024/2025 | Graded A+ What determines the direction in which a chemical equilibrium will shift when the concentration of one of the reactants is increased? The equilibrium will shift to the right, towards the formation of more products, to counteract the increase in reactant concentration. How can you assess the strength of an acid or base using pH and pOH values? The strength of an acid or base can be asse...

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

MCAT General Chemistry (Princeton Review) Questions and Answers | Latest Update | 2024/2025 | Already Passed What is the role of a Lewis acid and a Lewis base in a chemical reaction? A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. They interact to form a coordinate covalent bond where the base donates an electron pair to the acid. How does the concept of bond enthalpy relate to the strength of a chemical bond? Bond enthalpy (or bond dissoci...

Henderson-Hasselbach Equation - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - Separates sample based on size with smaller molecules eluting later. Ion-Exchange...

Exam 4 Chemistry Questions & Answers 2024/2025 Define Acid-Base Buffer - ANS-A solution that lessens the impact on pH from the addition of acid or base. How do buffers work? - ANS-Through the common ion effect When does the common ion effect occur? - ANS-When a given ion is added to an equilibrium mixture that already contains that ion, and the position of equilibrium shifts away from forming it. True/False: Any insoluble compound actually does dissolve to a slight extent. - ANS-True. W...

Coulter principle. - Answer-The ability to count and measure the size of particles using an electric circuit. Particles are moved through a small aperture, their presence causes a narrowing of the aperture, which leads to an increase in resistance.By using constant I, According to Ohms law (U= I * R), when R increases, U increases and pulse is generated. Parts and functions of the Coulter-counter - Answer-- Two spaces with a small aperture in between, capillary (contains the electrolyte sol...
