How do scientist measure CO2 levels from hundreds of years ago?
Air bubbles from ice cores taken from the North/South pole.
200
This is a reaction between an acid and a base that ends in a product that is neither an acid or a base.
Neutralization.
200
Define oxidation and reduction.
Oxidation is a process in which a reactant loses one or more electrons. Reduction is a process in which a reactant gains one or more electrons.
200
What is electrolysis?
The use of electrical energy to produce a chemical change.
200
What is the difference between configuration and conformation.
Configuration is how the atoms of a molecule are connected. Conformation is the shape they take at any given time.
200
Are our oceans acidic or basic?
Basic
300
What is a salt?
An ionic compound formed from the reaction between an acid and a base.

What is an aromatic compound?
An organic compound containing one or more benzene rings.
300
What element is responsible for corrosion and combustion?
Oxygen

What is a substance called when it has the ability to behave as either an acid or a base?
Amphoteric
400
If a compound loses electrons is it being reduced or oxidized?
Oxidized

What is the photoelectric effect?
The ability of energy from sunlight to knock electrons away from their atoms.
400
What is a cyclic alkene?
A structure in which the position of the double bonds alternate.

What keeps our blood at a ph between 7.35 and 7.45?
A buffer system. Primarily carbonic acid.

Explain the two major trends on the periodic table that effect redox reactions.
Left side loses e- easily(less ionization energy). Right side gains e- easily(high electronegativitiy).

What is Galvanization/what is it used for?
Coating iron with a thin layer of zinc which oxidizes turning into zincoxide protecting the underlying iron from rusting.
