|
What are the three layers of the planet?
|
Atmosphere, Hydrosphere, Lithosphere
|
|
|
What is an ore?
|
A solid material containing metals or other elements of intrest
|
|
|
To mine - or not to mine depends on what?
|
- Amount of ore at the site
- Percent of metal in ore - Type of mining/processing needed to extract metal - Distance of mine from refining facility - Metal's supply vs. demand status |
|
|
Why are gold, silver, and copper among the first elements discovered even though they are more rare than aluminum, iron and calcium?
|
They are often found in their elemental state due to their low reactivity, while others are reactive and must be refined from their ores
|
|
|
What are the differences between Au and Li?
|
Au is does not interact with any other element, while Li interacts with many elements
|
|
|
Where are the most reactive metals found?
Where are the least? |
- The most reactive metals are on the left side
- The least reactive are on the right side |
|
|
What is an oxidation
|
A chemical change in which a species loses electrons
Ex. Cu --> Cu++ + 2e- Oxidation (OIL) |
|
|
What is a reduction?
|
A chemical change in which a species gains electrons
Ex. Cu++ + 2e- --> Cu Reduction (RIG) |
|
|
What is the conservation of charge
|
Whenever one species gains electrons another is losing them.
(This means oxidation and reduction ALWAYS occur in the same reaction) |
|
|
What does the : in Mg: mean?
|
: represents 2 easily removed electrons
Ex. Mg: --> Mg++ + 2e- |
|
|
What is the answer to this equation?
Ag + e- --> ? |
Ag^0
|
|
|
What is the oxidizing agent?
|
It takes the electrons
|
|
|
What is the reducing agent?
|
It supplies the electrons
