metal in water equation
METAL mass x spicific heat capacity x temperature change = WATER m x 4.184J x temperature change
how chorates, hydroxides, carbonates dissociate
chlorides + 02, oxides + H2O, oxides + CO2
always soluble
NO3- (nitrate) C2H3O2-(acetate), alkali metals
carbonate, nitrate, phosphate, chlorate, sulfate, ammonium, hydroxide
CO3 2-, NO3 -, PO4 3-. ClO3 -, SO4 2-, NH4 +, OH -.
usually soluble (aq)
Cl-, Br-, I-, SO4 2-,
usually insoluble (s)

per-ate, ate, ite, hypo-ite
one more oxygen, base, one less oxygen, two less oxygen (SAME CHARGE)
lattice energy equation and meaning (Q in absolute value)
LE=kQ1Q2/d (Q1= one cation charge, Q2= one anion chargee, d=distance from nuclues of cation and anion)
order of gaining electrons for isoelectronics
p,s,d, core
strong acids

how to write anion lewis dot diagram
deffinition of atomic weight and mass number
number of protons (and electrons), number of nuclueons (p and n)
Avagadro’s number
6.023 E23
coffee cup calorimeter and bomb calorimeter equations
Cp x deltaT x m (of everything), C x DeltaT

-atoms were solid spheres of different colors

-law of nature: expination for re-occuring events

-conservation of matter: matter isnt gained or lost

-definite porportions: same porportion of element by mass in compound

-law of multiple porportions: ratio in binary compounds are all in porportions

Atomic Theory:

-atoms are smallest indistructable matter

-atoms of the same elements are the same (+vise versa)

-atoms combine in varying porportions forming compounds

-atoms rearrange their orientations in chemical reactions

plum pudding model, tested with cathode ray tube and discovered subatomic particles
bombarded gold and realized that some electrons bounced straight back! (discovered nucleus)
discovered charges of subatomic particles
found charge of electron by using different oil drops and took the smallest out of the ratio!
Gibbs equation
deltaG = deltaH -T x delta s (kj and kelvin!)
