Justin explained to me different chemistry topics that I was struggling with. These include Lewis dot structures, dimensional analysis and balancing equations. I recommend him to all!
I don't have much of a background in chemistry and have been struggling with it this semester. In just one session she taught me about grams, molarity, Lewis dot structures, molecular shapes, naming compounds and balancing equations. She taught it to me in a way that made it much easier and calmed my test anxiety. I definitely recommend her.
My son said the lesson gave him a very good review on his chemistry honor class. The concepts reviewed include the following: electronegativity, covalent bonds, polar covalent bonds, coordinate covalent bonds, bond polarity, molecular polarity, Lewis-Dot structures when there is an excess or dearth of electrons, Geometry, hydrogen bonding, ionic radii, and partial positive and negative charges. He thought it was very helpful.
