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!
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.
Frank worked with my son reviewing Nomenclature, Lewis Dot Structures, Molecule polarity and bonding. After working with Frank, my son was confident in taking a retest on one he had previously failed and was able to score an 87. Thank you Frank!!
