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.
I am a transfer student and i don't understand how to do these formulas. 1. Write a balanced equation for the reaction in which dinitrogen pentoxide (N2O5) reacts with water to produce nitric acid (HNO3) 2. Phosphorus reacts with bromine to produce phosphorus tribromide (PBr3).Write the balanced equation for this reaction. 3. Magnesium reacts with titanium (IV) chloride (TiCl4) to produce magnesium chloride (MgCl2) and titanium.Write the balanced equation for this reaction. 4.
