Chemistry Reaction Types Flashcards
Combination reactions are ___ in which two or more reactants form one product
reactants
Combination ___ can occur when elements react to form compounds, such as during the formation of sulfur dioxide by burning sulfur
reactions
Combination reactions can also occur when two compounds react to forma new ___.
NH3 (g) + HCl (g) -> NH4 Cl (s)
compound
A ___ reaction is defined as one in which a compound breaks down into two or more substances, usually as a result of heating or electrolysis
decomposition reaction
___ is a specific process that causes the decomposition of a compound by passing an electric current through the reactant
electrolysis
A ___ reaction is the breakdown of mercury (II) oxide (the sign delta represents the addition of heat):
2HgO (s) -> delta 2 Hg (l) + O2 (g)
decomposition
Single-displacement ___ occur when an atom (or ion) of one compound is replaced by an atom of another element
reactions
Single-displacement reactions are often further classified as ___ reactions
redox
Because many ___, including some displacements, involve ions in solution, their net equations can also be written in ionic form
reactions
When ___ reactions occur, there are usually spectator ions that do not take part in the overall reaction but simply remain in solution throughout
displacement
Net ionic equations are important for demonstrating the actual ___ that occurs during a displacement reaction
reaction
In double-displacement reactions, also called ___, elements from two different compounds displace each other to form two new compounds
metathesis reactions
Metathesis reactions occur when one of the ___ is removed from the solution as a precipitate or gas, or when two of the original species combine to form a weak electrolyte that remains undissociated in solution
products
___ are a specific type of double displacement that occurs when an acid reacts with a base to produce a solution of a salt and a water
neutralization reactions
A reaction that involves the transfer of electrons from one species to another is an ___ (redox) reaction
oxidation-reduction
