Lora Your chemistry tutor
I am a science tutor who loves science! I recently graduated with my Bachelor of Science in Chemistry and am on the pre-medical track. Throughout college, I led independent supplemental study sessions in Principles of Genetics, making my own practice problems for students to use. I also tutored high school chemistry and middle school science in my free time, and have tutored since I was in high school. I have experience working with a variety of age ranges, from younger kids to college students. I love to spread my enthusiasm for science and personalize my tutoring to the students' needs. I love to lead engaging sessions and enjoy including real-world examples in my teaching. I am also a visual learner, so I draw diagrams to help explain concepts and will create specific practice problems for our session, along with answer keys for you to take away and continue to practice after our session. I request that my students send me their questions and topics of interest ahead of time (preferably 24 hours before), so I am able to sufficiently prepare material so that we can have a successful lesson. Let's work together not only to succeed in your science courses, but to enjoy the journey there!

Chemistry concepts taught by Lora
Student and Tutor reviewed core Chemistry concepts related to chemical equilibrium. They practiced sketching potential energy diagrams for endothermic reactions, applied Le Chatelier's Principle to predict equilibrium shifts for changes in concentration, pressure, and temperature, and interpreted concentration-time graphs. The session concluded with setting up and solving a complex equilibrium problem using an ICE table and the quadratic formula; the Student was advised to practice further and inquire about calculator usage for the quadratic formula.
Potential Energy Diagrams
Le Chatelier's Principle: Stressors & Shifts
Equilibrium Concentration Graphs
ICE Tables for Equilibrium Calculations
Solving for 'x' with the Quadratic Formula
Reaction Quotient (Q): Predicting Equilibrium Direction
The Student and Tutor introduced gas laws, covering pressure, volume, temperature, and moles, and practiced calculations using the ideal gas equation and related laws. They confirmed a recurring Friday class and discussed rescheduling to Wednesday for future test preparation. The Tutor will upload notes and reach out to schedule a Wednesday session for more practice.
The Ideal Gas Equation (PV=nRT)
Gas Properties & Pressure
Avogadro's Law (Volume-Mole Relationship)
Charles's Law (Volume-Temperature Relationship)
Ideal Gas Assumptions & Constants
Boyle's Law (Pressure-Volume Relationship)
The Student and Tutor reviewed Le Châtelier's Principle in Chemistry, covering how changes in concentration, pressure/volume, and temperature affect reaction equilibrium. They practiced applying these principles to predict reaction shifts and discussed the unique impact of temperature on the equilibrium constant. The Student mentioned an upcoming quiz on ICE tables and Le Châtelier's Principle, and the Tutor provided additional study time recommendations.
Impact of Pressure and Volume Changes on Equilibrium
The Equilibrium Constant (K_eq) and its Determinants
Impact of Temperature Changes on Equilibrium
Impact of Concentration Changes on Equilibrium
Le Chatelier's Principle: Understanding Equilibrium Shifts
The Student and Tutor focused on heat transfer, specifically exploring the relationship between intermolecular forces, boiling points, and vapor pressure. They also discussed the Q=MCΔT equation, practicing problems involving specific heat capacity and thermal equilibrium. The Tutor recommended reviewing different types of IMFs and practicing the covered problem types for an upcoming exam.
Intermolecular Forces (IMFs) & Molecular Separation
The Interplay of IMFs
Boiling Point
& Vapor Pressure
Boiling Point: Atmospheric Pressure & Altitude
Quantitative Heat Transfer: Q = mcΔT
Heat Transfer at Equilibrium (Q_system = -Q_surroundings)
The Student and Tutor practiced solving various stoichiometry problems in chemistry, covering conversions between grams, moles, and different compounds using molar mass and mole ratios. They also tackled problems incorporating density and kilogram-to-gram conversions, with the Tutor emphasizing methodical unit cancellation. The session prepared the student for an upcoming test on stoichiometry.
Dimensional Analysis (Ladder Method)
Molar Mass Calculations
The Mole Concept & Avogadro's Number
Molar Ratio (from Balanced Equations)
Integrating Density into Stoichiometry
The session primarily focused on reviewing the Student's chemistry homework, covering topics such as hybridization, resonance structures, bond length, formal charge, and molecular geometry. The Tutor systematically explained core concepts related to multiple bonds, sigma and pi bonds, atomic radius, and bond order, working through specific problems and clarifying areas of confusion. The Student was encouraged to seek additional perspectives on particularly challenging questions.
