How does a platinum-rhodium catalyst work?
Platinum and rhodium are commonly used jointly in catalytic converters. A platinum-rhodium catalyst is a reduction catalyst, which is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the nitrogen oxides (NO and NO2, together called NOx) emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO => N2 + O2 or 2NO2 => N2 + 2O2
What is Ga(NO2)3?
Ga is Gallium and NO2 is the nitrite anion. Thus, Ga(NO2)3 is gallium nitrite.
The polyatomic ion repersented by the forula no2- is the?
The polyatomic ion represented by the formula NO2- is the nitrite ion.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What will be the formula for one formula unit of a compound between NO2 and Be?
The formula for one formula unit of the compound between NO2 and Be will be Be(NO2)2. Beryllium forms a +2 cation and nitrite (NO2-) is a polyatomic ion with a -1 charge, so two nitrite ions are needed to balance the charge of one beryllium ion in the compound.
