Types of reactions
A + B -> AB
What is synthesis?
CO -> C + CO2
2 CO ->1 C +1 CO2
BaS + PtF2 -> BaF + PtS
1 BaS + 1 PtF2 -> 1 BaF + 1 PtS
H2SO4 + NH4OH -> H2O + (NH4)2SO4
1 H2SO4 + 1 NH4OH -> 1 H2O + 1 (NH4)2SO4
A synthesis reaction is to...
build elements into compounds
AB -> A + B
What is decomp?
P4 + H2 -> PH3
1 P4 + 6 H2 -> 4 PH3
MgF2 + Li2CO3 -> MgCO3 + LiF
1 MgF2 + 1 Li2CO3 -> 1 MgCO3 + 2 LiF
NH3 + O2 -> NO + H2O
4 NH3 + 5 O2 -> 4 NO + 6 H2O
a decomp reaction is to
break compounds into elements
XY + A -> AY +X
What is single replacement?
NO2 -> NO + O2
2 NO2 -> 2 NO + 1 O2
F2 + H2O -> OF2 + FH
2 F2 + 1 H2O -> 1 OF2 + 2 FH
Fe2S3 + H2O + O2 → Fe2O3 + H2SO4
1 Fe2S3 + 3 H2O + 6 O2 → 1 Fe2O3 + 3 H2SO4
single replacement reaction is
a when a single element switches sides of equation thats part of a compound
XY + AB -> XB + AY
What is double replacement?
Na3PO4 + KOH -> NaOH + K3PO4
1 Na3PO4 + 3 KOH -> 3 NaOH + 1 K3PO4
CH4 + S -> CS2 + H2S
1 CH4 + 4 S -> 1 CS2 + 2 H2S
C2H6 + O2 -> CO2 + H2O
3 C2H6 + 7 O2 -> 4 CO2 + 6 H2O
A double replacement reaction is
when to elements in the compound switch
_ + O2 -> CO2 + H2O
What is combustion?
AgNO3 + Cu -> Cu(NO3)2 + Ag
2 AgNO3 + 1 Cu -> 1 Cu(NO3)2 + 2 Ag
C2H4 + O2 -> CO2 +H2O
1 C2H4 + 3 O2 -> 2 CO2 + 2 H2O
S + HNO3 -> H2SO4 + NO2 + H2O
1 S + 6 HNO3 -> 1 H2SO4 + 6 NO2 + 2 H2O
a combustion reaction is
a reaction that burns and includes oxygen and releases carbon dioxide
