Trusted teacher: Chemistry is about learning the secrets of nature. How a glass of cold water become warmer as the time passes? Why the rusting of iron takes place in months or years? All these facts and many other things which could be discussed under the chemistry are fun to learn. I'll make sure that my classes will help each of the student to understand the principles, laws and application of the chemistry. So that none will face any problem or difficulty in their O/A levels Chemistry. Our classes will be constructed on 3 points: - Instructional: This is the time, I tell my students about the background and the understanding of the lesson. So that the student will have the idea that what the topic is focusing and what is the history for this. - Discussion: Here I allow my students to ask questions and they are free to debate about the topic with me. Discussion is very important, as it allows the student to think beyond the limits and it also help them in building their communication skills. - Review & Past-paper Solution: After all the discussions, we review the topic from the beginning and solve the relevant past paper questions for the topic. So the student after every class is confident enough not just about the learning but also for being able to attempt the questions. So each class is actually a little step to achieve the goal of performing their best in exams. Becoming aware of the simplicity of the subject, unleashing your potential and having confidence in your abilities. Our sessions will be of 60 to 90 minutes(depending upon the need of the student and the lesson). Keeping the Psychology in mind that learning sessions of straight hours are hectic for students too and their potential for learning decreases after 90 minutes of a class. 3 classes per week for the consistent learning. *Classes delivered via Zoom through Good Notes. *Assignments for each topic. *Assessment after every two weeks.

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
