1
New cards
acid-base reactions (neutralization reactions)
form water (H + OH = H2O) and a salt
2
New cards
gas evolution reactions
form gas as a product (H2CO3 -> H2O + CO2)
3
New cards
H2CO3
H2O + CO2
4
New cards
H2SO3
H2O + SO2
5
New cards
NH4OH
H2O + NH3
6
New cards
oxidation reduction reaction (redox reaction)
involve the transfer of electronss
7
New cards
signs of redox reaction
substance reacts with elemental oxygen
metal reacts with nonmetal
one substance transfers electrons to another substance
metal reacts with nonmetal
one substance transfers electrons to another substance
8
New cards
combustion reaction
a type of redox reaction,
carbon, hydrogen, and oxygen form co2 and h2o
carbon, hydrogen, and oxygen form co2 and h2o
9
New cards
theoretical yield
the amount of product that can be made in a chemical reaction based on the amount of limiting reactant
10
New cards
percent yield
actual/theoretical * 100
11
New cards
ionic bond
electrons are transferred
12
New cards
covalent bond
electrons are shared
13
New cards
elemental exceptions to the octet rule
helium and hydrogen (duet rule)
14
New cards
pauli exclusion principle
orbitals may hold no more than two electrons with opposing spins
15
New cards
hund's rule
when filling orbitals of equal energy, electrons fill them singly first, with parallel spins
16
New cards

25
New cards
light speed
3.0 * 10.8m/s
26
New cards
wavelength
the distance between adjacent wave crests
27
New cards
frequency
the number of cycles of crests that pass through a stationary point in one second
28
New cards
photon energy
shorter wavelength, greater the energy in this photon
29
New cards
gamma ray
shortest wavelength photons; are harmful to humans because of their frequency
30
New cards
relation between wavelength and frequency
inverse: greater wavelength = shorter frequency
31
New cards
chromium electron configuration
[Ar] 4s1 3d5
32
New cards
copper electron configuration
[Ar] 4s1 3d10
33
New cards
atomic size
moving right = decreases, moving down = increases
34
New cards
ionization energy
moving right = increases, moving down = decreases
35
New cards
metallic character
(not atomic size) move right = decreases, move down = increases
