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.
An electron source is a bond or a lone pair of electrons. It is either a p bond or a lone pair on an atom of relatively high electron density in a molecule or ion, or a bond that must break during a reaction. An electron sink is an atom on a molecule or ion that can accept a new bond or lone pair of electrons.
