unit 6 Flashcards
Synthesis
A + B = AB
decomposition
ab = a + b
single replacement
if you’re replacing a POSITIVE ION: a + bd = b + ad
If you’re replacing a NEGATIVE ION: a + bd = d + ab
double replacement
solids: AB + CD = AD + BC
formation of water (acid-base)
HA + BOH = AB + H2O
formation of a gas: AB + CD = AD + BC
Combustion
complete: CxHy + O2 = CO2 + H2O
the products are carbon DIOXIDE and water
incomplete: you get CO + H2O or C + H2O
single replacement positive vs negative ion
positive: A + BC = B + AC
negative: A + BC = C + BA
what tends to dissolve in water
nitrates, chlorates, chlorides, bromides, iodides, sulfates
what tends to NOT dissolve in water
SULFIDES, carbonates, chromates, phosphates, hydroxides
oxidized
lose electrons
