Gravimetric analysis

________ is used to determine an unknown element in a precipitate reaction.

2

Hydrocarbon combustion

________: carbon + hydrogen (and sometimes oxygen) is ignited and produces CO2 and water, sometimes other compounds as well depending on the elements present.

New cards
3

Synthesis reaction

________: when elements or simple compounds are combined to form a single, more complex compound.

New cards
4

redox reactions

In ________, electrons are swapped between reactants and the oxidation states of the reactants are changed.

New cards
5

Decomposition

________: opposite of synthesis- occurs usually in the presence of heat.

New cards
6

7

Oxidation reduction

________ (redox): results in change of oxidation state (only for some)

New cards
8

Precipitation

________: two aqueous solutions mixing to create a solid precipitate.
