Oxidation number of oxygen

From Lewis structure we can determine oxidation numbers of oxygen. When oxidation number is -2, oxygen can adopt different forms: oxide anion, hydroxide anion or covalent bonds. Oxidation number of oxygen [REDOX INDEX] [Redox SEQUENCING] Rafa

Oxidation numbers

Hi We can use Lewis diagrams and values of electronegativities when we introduce the concept of oxidation number. This way, oxidation numbers are the values from electron bookkeeping. Determination of changes in oxidation number [REDOX INDEX] Rafa

Kinematics – Basic Exercise

Hi After defining position vectors, displacement, change in velocity, and acceleration we can provide opportunities to students to apply them. We can propose basic exercises as this one: Kinematics – Basic Exercise [KINEMATICS – INDEX] [Kinematics: Topic Sequencing] Rafa
