DAT General Chemistry Questions and Answers | Latest Update | 2024/2025 | Graded A+ How is the periodic table arranged to reflect the properties of elements? The periodic table is arranged by increasing atomic number, with elements grouped into columns (groups) and rows (periods) that reflect similar chemical properties and trends in atomic structure. What is the role of a chemical equation in representing a chemical reaction? A chemical equation represents a chemical reaction by...

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...
