• Aug 18, 2025 balancing equations and identifying reaction types answers e compound). Check for energy involvement (e.g., heat, light for combustion). Apply rules or use reaction series (activity series for single replacement). Use context clues such as physical states (solid, liquid, By Jesse Schiller
• Jun 24, 2026 advanced organic chemistry part b reaction and sy configuration. SN1: Unimolecular substitution proceeding via carbocation intermediates, often resulting in racemization. Electrophilic Addition: Typical in alkene chemistry; involves the addition of an electrophile to the π bond, forming carbocation intermediates. By Carol Bartell
• Nov 11, 2025 additivity of heats of reaction lab answers m of individual heats, weighted by their proportions. Example Calculation: If: ΔH A = -500 kJ ΔH B = -300 kJ and the mixture contains 2 mol of X and 3 mol of Y, then: Expected total heat: ΔH total = (2 mol × ΔH A ) + (3 mol × ΔH B ) = (2 × -500) + (3 × -300) = -1000 - 900 = By Cyril Harber-Kub
