Combustion

Adding CO2 to Bromathymol Blue

Adding CO2 to bromothymol blue changes the colour with the changing PH. CO2 makes water more acidic→ blue to yellow

Celluar Respiration

All living things use sugar (glucose) to produce the energy needed to carry out out life functions

Celluar Respiration is an example of a

Combustion reaction that produces emissions

Combustion reactions

require some kind of fuel reacting with oxygen to create energy and oxides

C8H18+ O2→ 8CO2 + 9H2O

The type of oxide produced

Heavily depends on the atoms present in the fuel

Carbon reacting with oxygen → CO2

Hydrogen reacting with Oxygen→ Water

The contribution of emmissons

To an enhanced greenhouse effect (build up of gasses in the atmosphere) and climate change. The oxides are called emmisons

Hydrocarbon

Are compounds with carbon and hydrogen

the combustion of hydrocarbons can be either complete or incomplete

Complete Combustion

Combustion occurs when hydrocarbon is burned with an excess amount of oxygen which produces O2

Incomplete Combustion

Combustion occurs when there is not enough oxygen to produce CO2 so it produces CO

Asccociated with inefficienct combustion processes

CO poisoning

Occurs when CO binds to RBCs instead of oxygen. Carbon monoxide has a higher affenity than oxygen for hemoglobin

Other Oxides

Sulfur Dioxide (SO2) commonly from the combustion of H2S

Sour Gas

A natural gas that has H2S in it. H2S is extremely toxic to humans and will combine with water to form an acid which corrodes pipelines

The removal of H2S

The removal of H2S from natural gas, the gas is sweetened by the burning of the H2S with a flare producing SO2 and SO3

Oxides and Nitrogen Oxides

Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide

Nitrogen Oxides- N2 and O2

Sources of O2→ Natural

Hot springs. Volcanic outgassing. Human made→ emmisons from: automoblies, refining crude oil, pulp and papermills

Nitrogen

Is naturally found in our atmosphere (78%) largest portion of air becomes very harmful when converted to NOX at high temperatures.

sources→ Human Made→ fossil fuels, powerplants, automobiles

Natural→ forest fires

Compounds that when mixed with water create an acid

CO2, NO, NO2, SO2 this in turn produces acid rain when they all combine in the air from admissons

Acid Deposition

Occurs when acidic compounds from the atmosphere are absorbed by Earth’s surface

Wet Deposition

emmisons that contact water in the atmosphere dissolve and fall to the ground as percipatation

Dry Deposition

emmisons are transported by winds and depostisted on the Earth’s surface when it comes into contact with groundwater

Alberta and Dry depostion

Alberta has a dry climate, so most deposition is dry.
