1amu = 1/12 the mass of 1 atom of carbon 12 (convenient)
Choose an answer
1 amu 2 joules
3 gram 4 mole
Don't know?
mixture:
heterogeneous or homogeneous
matter
pure substance:
element or compound
1. all matters are made up of small particles called atoms
2. elements have only one type of atoms
dalton's atomic theory 3. compounds have 2 or more types of atoms in a constant ratio
4. law of conservation of mass
5. properties of one kind of atom differs from another
, atomic and ionic symbols: what
is A and Z?
same proton number but diff neutron number
isotopes
ex: carbon
amu 1amu = 1/12 the mass of 1 atom of carbon 12 (convenient)
average mass abundance * isotopic mass added up
covalent compound nonmetals sharing electrons
formula:
-cation then anion
-anion ends with -ide
-transition metalsL: charge denoted by roman letter
-with 5h20 -> (penta)hydrate
ionic compound
due to electrostatic forces of attraction
dissolve in water
electronically neutral overall
molecular vs empirical formula actual number of each type vs simplified ratio
determination of empirical mass -> moles -> divide by lowest moles -> ratio
formula
solvent - highest concentration
solute - lower concentration
solution
mass percentage mass of component/solution
volume percentage volume of solute / solution
parts per million mass of solute/mass of solution x 10^6
parts per billion mass of solute/mass of solution x10^9
dilution of a solution C1V1 = C2V2
1. least number of atoms
balancing equations
2. balance oxygen last
ions that do not participate in a reaction
spectator ions
eliminate in net ionic equation
precipitation reactions dissolved substances combine to produce a solid product
reaction where H+ transferred
Acid - donates proton; produces h3o+ in water
acid-base reactions
base - accepts proton ; produces oh- in water
NEUTRALIZATION REACTION - acid+base -> salt+water
weak acids only partially dissociate, represented by double
strong vs weak acids
