single replacement, combination, decomposition reactions Flashcards
single replacement reaction formula?
A + BC (aq) = AC (aq/s) + B
single replacement reaction defined as?
an element and an aqueous ionic compound react to form:
- a new aqueous or solid ionic compound
- and a new element
(reactant element “kicks off” the element in the reactant ionic compound)
if the reactant element in a single replacement reaction is a metal or H, it will replace the ___ in the ionic compound
metal
if the reactant element in a single replacement reaction is a nonmetal, it will replace the ____ in the ionic compound
nonmetal
what requirement needs to be met for an element/H to replace an element in the compound in a single replacement reaction?
element needs to be HIGHER on the activity series/more reactive than the element in the compound to replace it!
if element can’t replace the element in an ionic compound in a single replacement reaction, what happens?
nothing- there will be no reaction
what are combination reactions defined as? formula?
2 individual elements combine to form a compound
A + B = AB
decomposition reactions are defined as? formula?
One compound breaks down into smaller components or its individual elements
AB = A + B
