30
naming ionic compounds
name of cation + base name of anion and -ide; if cation can form multiple charge add that
31
naming binary acid
hydro + base name of nonmetal + -ic + acid
32
naming oxyacids with -ate oxyanion
base name of oxyanion + -ic + acid
33
naming oxyacids with -ite oxyanion
base name of oxyanion + -ous + acid
34
weak acids
acetic acid, hydrofluoric acid
35
weak base
ammonia
36
combustion reactions
substance + oxygen; carbon forms co2, hydrogen form h2o
37
alkali metals (M) and haogens (X)
2M + X2 = 2MX
38
halogens
react to form metal halides; 2 M + nX2 = 2MXn
39
dilution
M1V1 = M2V2 (number of mols stays the same)
40
acid base rxn
forms water, salt (if C is present, then CO2 as well)
41
redox reaction
electrons transfer from one reactant to another; any reaction with change in oxidation states from reactant to products
42
rules for oxidation states
1. ox state of atom in free element is 0
2. ox state of monoatomic ion is = to charge
3. sum of ox of all atoms is = to 0 in neutral atom, or ionic charge
4. 1A = +1, 2A = +2 always
5. nonmetals assigned: F, H, O, 7A, 6A, 5A
43
Oxidation
loss of electrons
44
reduction
gain of electrons
45
oxidizing agent
is reduced
46
reducing agent
is oxidized
