Final exam material

Question 1

Amorphous solids

Answer 1

Atoms vibrate in place in a random pattern rather than a fixed one, leading to a more random and clustered assortment of atoms

Question 2

acid nomenclature

Answer 2

ate —–> ic + acid
ite —–> ous
ide ——> hydro + ic

Question 3

Hydrogen bonding

Question 4

dipole-dipole forces

Question 5

How is chemical symbol arranged

Answer 5

Proton number (atomic #) goes on bottom while the mass number or protons plus neutrons goes on top

Question 6

electro magnetic spectrum from highest to lowest energy

Answer 6

Gamma rays > X-rays > ultraviolet > visible light > infrared > microwaves > radio-waves

Question 7

ordering of a phase diagram

Answer 7

Solids are in a region of low temperature, liquids are in between the gas and solid, gas’s are lower pressure higher temperature and super critical fluids are usually top right with a high temperature and high pressure

Question 8

electron affinity

Answer 8

amount of energy RELEASED when an electron is added to a molecule

*exothermic
Higher electron affinity means higher pull to that electron as well

Question 9

Ionization energy

Question 10

crystalline vs amorphous solid

Answer 10

crystalline structures are highly repeating and highly ordered

Amorphous structures lack this order and are more random in their atomic assortment

Question 11

How are pi bonds formed

Answer 11

unhybridized p orbitals mix, more than one bond
