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.
Silver(I) oxide produced by reacting lithium hydroxide with a very dilute silver nitrate solution. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide.his oxide is used in some silver-oxide batteries, as is the silver(I,III)oxide, Ag 4 O 4. In organic chemistry, silver oxide is used as a mild oxidizing agent.
