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 learned about 15 hours ago

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.

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.
