Chapter 3 Flashcards
What is the equation for the ozone formation?
Energy + 3 O2 = 2 O3
What must be absorbed for Energy + 3 O2 = 2 O3 reaction to occur?
Energy because it has to be endothermic
What is an allotropic?
2 or more forms of the same element that differs in chemical structure and therefore their properties
Ozone is what form of oxygen?
Allotropic
Where is the troposphere?
Where we live
What is the stratosphere?
The Ozone layer
Where is atmospheric pressure highest?
Closer to the sea level
How does ozone increase?
From pollution
What are valence electrons?
The electrons in the outermost energy levels
What are valence electrons responsible for
Responsible for chemical bond formations
What tells you the number of valence electrons on the periodic table?
The group number
How many groups are there on the periodic table?
8 groups (1-8)
Who developed a method of visual representation for the valence electrons?
G.N. Lewis
What represents the valence electrons?
Dots around the symbol of an atom
Whats the octet rule?
In chemical reactions, atoms tend to gain, lose or share electrons so to have 8 valence electrons
What are the 2 elements that only have 1 element to add
Hydrogen and helium
What is the flame test?
different elements give different colors to a flame
What is a wavelength (l)?
The distance traveled between successive peaks
What is the frequency (n)?
Number of waves passing a fixed point in one second
When theres longer wavelength whats the frequency?
Lower frequency
What happens to an ultraviolet light when it touches a molecule?
It causes it to break
What happens to an infrared light when it touches a molecule?
It causes it to vibrate
What happens to an microwave light when it touches a molecule?
It causes it to rotate
What are the consequences of UV radiation
energy associated to radiation, length of time of exposure, and the sensitivity of the organism to that radiation
What is the Chapman cycle?
A steady state condition
