Trusted teacher: Thermal changes accompanying physical and chemical changes Thermal changes accompanying physical changes - melting temperature It is the temperature change when one mole of solute is dissolved in a given amount of solvent (The amount of heat energy absorbed or released when one mole of solute is dissolved in a given amount of solvent). During the dissolution process: two processes occur: A- Dissociation: the breaking of bonds (endothermic reaction) Sodium and chloride ions dissociate from the crystal lattice as a result of the ionic bond breaking. The energy absorbed to break the bond is called the heat of the crystal lattice (bond energy). - Crystal lattice temperature: It is the energy needed to break the bond between ions in the crystal lattice. B- Hydration: The dissociated ions bind with water molecules to form hydration ions (exothermic process). Rehydration temperature: It is the amount of heat released when hydrating ions bind to water molecules. If the crystal lattice temperature > heat of hydration Dilution temperature: It is the heat change per mole of solute when diluted from a concentrated solution to a dilute solution. (It is the heat change of one mole of solute when diluted in a large amount of water (about 1000 moles of solvent)). Sedimentation temperature: The amount of heat released when one mole of an insoluble substance is completely precipitated. - heat of combustion It is the amount of heat released when one mole of a substance is completely burned in an abundance of oxygen. (The reaction is always exothermic). Formation temperature: It is the amount of heat released or absorbed when one mole of a compound is formed from its elemental elements so that the elements are in their standard state. (at 25 °C, a pressure of 76 x g). Note: Heat of formation of the elements = zero

12€Mastering Chemistry: A Tutor for High School & University Students
Chemistry is often taught as a series of facts to memorize, but at its heart, it's a beautiful and logical story about how the world works at the molecular level. As a master student of theoretical and computational chemistry, I don't just teach you what happens; I teach you the fundamental why. This class is designed for students who want to truly understand chemistry, not just pass a test. Whether you're a high school student grappling with stoichiometry, an undergraduate diving into organic chemistry, or simply a curious mind wanting to understand the world around you, this course is for you. I believe that anyone can understand chemistry with the right guidance. My goal is to be that guide. I'm here to help you, whether you're feeling lost in class, preparing for final exams, or starting a university course that feels overwhelming. I adapt to each student's unique needs and learning style. I can help you master: The Atom and Periodic Table: Understanding the building blocks. Chemical Bonding: How and why atoms stick together. Stoichiometry: Mastering mole calculations and chemical reactions. Solutions and Concentration : Making sense of molarity and dilutions. Acids, Bases, and pH : Demystifying protons and logarithms. Thermodynamics and Kinetics: Understanding energy and reaction rates. And more! Whether it's physical chemistry, organic chemistry, or inorganic chemistry, we can explore it together. We'll work at your pace, fill in any gaps in your knowledge, and build your confidence step by step.
