1 Anemometer: A tool used by meteorologists to measure wind speeds. 2  Speed: How fast or slowly something is moving.  Revolutions per minute (rpm): How many times something goes around in a complete circle, or rotates, in one minute. The anemometer you will make in this exercise measures the wind speed in rpm.
Electron acceptors participate in electron-transfer reactions. In this context, the oxidizing agent is called an electron acceptor and the reducing agent is called an electron donor. A classic oxidizing agent is the ferrocenium ion Fe(C. 5H.
Valence Shell Electron Pair Repulsion (VSEPR) Theory is a simple, qualitative model that allows the prediction of an approximate molecular shape, given a valid Lewis structure of a molecule.SEPR theory treats each pair of electrons at an atom  either bonds or lone pairs  as a localized region of electron density, directed outward from the atomic centre. The predicted molecular shape will be such that the bonds and lone pairs are arranged so as to minimize repulsions and maximize the space among them.
