Marshall University CHM 211 Final
Acetate - ✔️✔️CH3COO-
acid-base reaction - ✔️✔️When an acid and base mix together, neutralize one
another's properties, and form a salt.
Ammonium - ✔️✔️NH4+
angular momentum quantum number - ✔️✔️symbolized by l, indicates the shape of the
orbital
Anion - ✔️✔️high first ionization energy, very negative EA
Anion Trend - ✔️✔️are larger than the atom from which they were formed
antibonding MO - ✔️✔️ex) 1s - 1s = sigma 1s**
has higher energy
atomic size trend - ✔️✔️increases down and to the left
atomic symbol - ✔️✔️A = mass number (upper)
Z = atomic number (bottom)
Bent electron geometry - ✔️✔️<120 degrees
AX2E
AX2E2
sp2
bond energy equation - ✔️✔️ΔH(rxn) = ∑[ΔH(reactant bonds broken)] + ∑[ΔH(products
bonds formed)]
product bonds formed are negative
Bond energy trend - ✔️✔️higher bond order = higher BE = shorter bond length =
stronger bond
Bond length trend - ✔️✔️increases down a group, decreases across a period
bond order - ✔️✔️the number of bonds between atoms: 1 for a single bond, 2 for a
double bond, and 3 for a triple bond
bond polarity and angle - ✔️✔️a molecule with a linear shape --> dipoles cancel
, a molecule with a bent shape --> dipoles don't cancel
bonding MO - ✔️✔️ex) 1s + 1s = sigma 1s
calculating moles of solute from diluted solution - ✔️✔️M(dil) x V(dil) = # mol solute =
M(conc) x V(conc)
calorie (cal) - ✔️✔️1 cal = 4.184 J
calorimetry equation - ✔️✔️q=mcΔT
Carbonate - ✔️✔️CO3 (2-)
Cation Trend - ✔️✔️are smaller than the atom from which they were formed
cations - ✔️✔️low first ionization energy, slightly negative EA
Celcius to Fahrenheit - ✔️✔️F = 1.8C + 32
centimeter (cm) - ✔️✔️10^-2
Chemical Properties of Matter - ✔️✔️ability to burn, ability to rust, ability to decompose
Chlorate - ✔️✔️ClO3-
Chlorite - ✔️✔️ClO2-
Chromate - ✔️✔️CrO4 2-
combination reaction - ✔️✔️A + B --> AB
combustion reaction - ✔️✔️produces CO2 and H2O
common units of pressure - ✔️✔️1 atm = 1.01325 x 10^5 Pa = 101.325 kPa = 760
mmHg = 760 torr
Compound - ✔️✔️substance formed by the chemical combination of two or more
elements in definite proportions
covalent bond - ✔️✔️nonmetal + nonmetal
Cyanide - ✔️✔️CN-
