Co2,carbon dioxide evolves whenever combustion takes place.As the deodorant contain Hydrocarbon+ Alcoholic functional group.It would create co2 and water vapour.
Most countries. Anywhere where fossil fuels (coal, oil and natural gas) are burnt in transport, industry and electricity generation.
when you breathe out,the gas that is emitted is
nitrogen
If it is burnt with a gas such as oxygen then yes
Carbon is the gas most emitted in fridges, automobiles, factories, etc. This leads to the pollution.
.........Particulate matter........
Pretty sure you mean "E.G.R. Valve" and not ERG. E.G.R stands for Exhaust Gas Recirculation Valve. Instead of letting all of the gas out of the exhaust of the vehicle after the mixture is burnt in the compression cylinder, some of it is recirculated into the intake manifold. This is done because not all of the vaporized gas is burnt out of the mixture that goes into the compression cylinder. So this recycles some of the unburnt mixture, and reduces the amount of pollution emitted by your vehicle.
CO3
Particulate matter
Methane is the most likely gas that comes from flatulence.
When polyethylene is burnt carbon dioxide and water vapors are released.
Smoke, hot air, and various pollutants are typically emitted from a power plant stack. These byproducts are released as a result of burning fuels such as coal, oil, or natural gas to generate electricity.
