Commutator (electric) A commutator is a moving part of a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.
The word equation that would represent the formation of lithium oxide from lithium metal and oxygen is: lithium + oxygen to lithium oxide. In chemical symbols, the balanced chemical equation is expressed as: Li + O2 = Li2O.
Write a balanced chemical equation for each of the following chemical reactions. 1) Gaseous carbon dioxide and liquid water react to produce aqueous glucose (C6H12O6) and oxygen gas. 2) Aqueous lithium hydroxide reacts with phosphoric acid and yields lithium phosphate and liquid water. 3) Aluminum...
