Here’s what you need to do Stay ahead of your class lectures in the videos. The topics cover exactly what you will cover in class and break down the topic to make it simple to understand. In this video, we will discuss the trends in the properties of group-17 elements, such as the negative electron gain enthalpy, oxidation states, oxidising power of halogens etc.Ġ1:27 - Trends in the atomic properties like atomic size, ionisation enthalpy and electronegativity.Ġ1:32 - Trends in the negative electron gain enthalpyĠ4:31 - Trends in the oxidising power of halogens. The ACS General Chemistry Exam contains 70 multiple-choice questions and has a time limit of 110 minutes. Based off of Kaplan books (Bio/Biochem/Physics/Organic/General Chemistry), Khan Academy 300 page P/S notes, Uworld, 10 Altius FLs, NS/Blueprint MCAT Qbank.
