Fossil Fuel Combustion
chemicals in the air, can also cause harm to living things.
What are pollutants?
The neutralization of stomach acid with sodium bicarbonate is a natural process that occurs in the small intestine.
What is Digestion Chemistry
when any kind of chemical reaction breaks down any metal.
What is Corrosion
Two compounds that cause metals to rust
What is Water and Oxygen?
precipitation that has a lower pH than normal.
the process of neutralizing lakes through the use of limestone (calcium carbonate) which is a base.
What is Liming?
The red-brown colour pieces of metal that start flaking off
What is rust
Acts as a protective barrier that prevents oxygen and water from getting to the metal - temporarily
What is paint?
Carbon dioxide, water, and methane trap heat in the Earth’s atmosphere.
What are Greenhouse Gases?

Example of metal that resists corrosion
What is Gold?
A thin layer, the zinc does not chip or break off easily like paint.
What is Galvanization
Examples of this are: Methane, Coal, Gasoline
What are Fossil Fuels
A major by-product of industrial processes. It is also a product in the combustion of fossil fuels like natural gas.
What is Sulfur Dioxide
Although it is not shown in the chemical reaction above, there is another substance needed for rusting to occur.
What is Water?
metals are mixed together because when they are combined they have better characteristics
What are Alloys?
Carbon monoxide is a product of this reaction
What is Incomplete Combustion
To make sure that very little sulphur from any coal is released into the atmosphere this process
What is Sulfur Scrubbing
Word Equation for Iron Rusting
iron + oxygen -> iron oxide
One of the metals the easiest to corrode will always rust completely before the other even starts to rust.
What is Sacrificial Metal
