Reactions Flashcards
precipitate
compound which doesn’t dissolve in water (is solid)
precipitation reaction
Two compounds react and one product forms a precipitate
reaction that indirectly produces a gas
one product of a DD reaction is unstable and decomposes into a gas
neutralization reaction
Between an acid and a base, always produces water and a salt
synthesis reaction
two simple materials come together to form a product
A + B —> AB
decomposition reaction
a complex chemical is broken down into simpler components
AB —> A + B
combustion reaction
a compound containing H, C, and sometimes O is exposed to O2 and produces H2O and CO2
CxHy(O2) + O2 —> CO2 + H2O
single displacement/replacement
one element swaps places in a compound with another
A + BC —> B + AC
double displacement/replacement reaction
cations and anions switch places in two compounds
AB + CD —> AD + BC
Hydrate
compound with water
decomposition of a hydrate produces…
the compound and water, now seperate
decomposition of a metal carbonate…
produces CO2 and the solid metal oxide
decomposition of a metal nitrate…
produces metal nitrite and O2
