Chapter 4- Compounds And Stoichiometry Flashcards
1
Q
Molarity/ normality conversion
A
Molarity = Normality / n
n = number of protons, hydroxide ions, electrons, or ions produced or consumed by the solute
2
Q
Carbonic acid
A
H2CO3
3
Q
Sulfuric acid
A
H2SO4
4
Q
Molecular formula vs. empirical formula
A
Molecular- exact number of atoms
Empirical- simplest whole number ratio
5
Q
Combustion reaction
A
Products: CO2 and H2O
6
Q
Neutralization reactions
A
Acids and bases combine to produce salt and water (usually)
Type of double displacement reaction
7
Q
Ammonium
A
NH4 (+)
8
Q
Nitrate
A
NO3 (-)
9
Q
Nitrite
A
NO2 (-)
10
Q
Cations vs. anions
A
Cations - (+) usually metals
Anions - (-) usually nonmetals
11
Q
Electrolytes
A
Dilutes that enable solutions to carry currents (due to ions in solution)
Strong- dissociates completely
Weak- doesn’t dissociate
12
Q
Acetone
A
C3H6O
