Generally platinum, sometimes palladium or rhodium, rarely other metals as: Ce, Mn, Fe, Cu, Ni.
Platinum is commonly used, or other metals such as palladium and rhodium (basically the catalyst is a precious metal)
that is true
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
The exhaust system of your automobile is analogous.
smog is the scientific term
Yes, automobile exhaust contribute to ozone hole. The automobiles release greenhouse gases which in turn deplete the ozone layer.
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
Exhaust tec means TORQUE EXPANSION CHAMBER it increases power and mileage of automobile
f an automobile had a 100 efficient engine would it exhaust the surroundings?
It change the toxic gases into non toxic gases (that are exhausted)
that is true
Smog.
No use for exhaust in car air conditioning
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
The most toxic 'metal' pollutant would be lead.Other pollutants present in the automobile exhaust are:HydrocarbonsNitrogen oxidesCarbon MonoxideCarbon Dioxide
Some exhaust systems use gaskets and some don't.
yes
The exhaust system of your automobile is analogous.
