Chapter 1/2 Flashcards
Which best describes what happens when molecular compounds melt?
Molecules arranged in a regular pattern change to an irregular pattern.
gas, liquid, or solid- lowest density of the three states
gas
gas, liquid, or solid- indefinite shape and high density
liquid
gas, liquid, or solid- temperature changes significantly infleunce the volume of this state
gas
gas, liquid, or solid- pressure changes influence the volume of this state more than the other two states
gas
gas, liquid, or solid- constituent particles are less free to move around than in other states
solid
What is more electronegative F or Cl
F-most electronegtive element
What is more electronegative
Si or N
N
What is more electronegative
O or S
O
What is more electronegative Rb or Sr
Sr
How to determine what bond is the most polar
elements bonded furthest away from each other on the period table
difference between a strong and weak acid
strong acids completely ionize, weak acids only partially ionize
ph formula
pH=-log[H+]
Ka formula
Ka=[H+][A-]/[HA]
pKa formula
pKa=-logKa
pH formula with pKa
pH=pKa + log [base(A-)/acid(HA)]
Note
Water molecules are polar molecules and form hydrogen bonds. Oil is nonpolar therefore water molecules do not form strong attractions to oil.
Archaea, Bacteria, or Eukarya- most inhabit extreme enviroments
Archaea
Archaea, Bacteria, or Eukarya- E.coli
bacteria
Archaea, Bacteria, or Eukarya- cells have a nucleus
Eukarya
Archaea, Bacteria, or Eukarya- cells have membrane bound organelles
Eukarya
Archaea, Bacteria, or Eukarya- many are multicellular
Eukarya
Archaea, Bacteria, or Eukarya- plants
eukarya
Archaea, Bacteria, or Eukarya- eukaryotes
eukarya
Archaea, Bacteria, or Eukarya- cells do not have a nucleus
archaea and bacteria
Archaea, Bacteria, or Eukarya- prokaryotes
archaea and bacteria
Archaea, Bacteria, or Eukarya- cells contain genetic material
all three
prokaryotes, eukaryotes, or both- lack membrane-bound organelles
prokaryotes
prokaryotes, eukaryotes, or both- are generally less than 2 micro (µm) meters
prokaryotes
prokaryotes, eukaryotes, or both- multicelluar
Eukaryotes
prokaryotes, eukaryotes, or both- contain mitochondria
eukaryotes
prokaryotes, eukaryotes, or both- unicellular
both
note
know strucutres of the prokaryotic cell
note
know rhe structures of the eukaryotic cell
note
size of organelles in eukaryotic cell ranked largest to smallest
cell nucleus, mitochondrian, ribosome, protein, amino acid, water molecule, protein
purpose of the nucleus in the eukaryotic cell
storage of genetic information
purpose of the ribosome in the eukaryotic cell
translation from RNA to proteins
purpose of the smooth endoplasmic reticulum in the eukaryotic cell
lipid synthesis and drug metabolism
purpose of the rough endoplasmic reticulum in the eukaryotic cell
surface on which ribosomes bind; takes part in protein synthesis
purpose of the mitochondria in the eukaryotic cell
energy metabolism and synthesis of ATP
note
study functional groups
