classify the following

Question

Classify the following reactions as synthesis, decomposition, single displacement, double displacement, precipitation, acid-base neutralization, oxidation-reduction, or combustion. Each reaction can be classified with more than one of these terms.

Hg(l)+S(s)⟶HgS(s)

Fe(s)+Cu(C2H3O2)2(aq)⟶Cu(s)+Fe(C2H3O2)2(aq)

Pb(NO3)2(aq)+2KI(aq)⟶PbI2(s)+2KNO3(aq)

2K(s)+2H2O(l)⟶2KOH(aq)+H2(g)

H2SO4(aq)+Mg(OH)2(aq)⟶2H2O(l)+MgSO4(aq)

C8H16(l)+12O2(g)⟶8CO2(g)+16H2O(g)

Answer 1

Hg(l)+S(s)⟶HgS(s) synthesis and precipitation

Fe(s)+Cu(C₂H₃O₂)₂(aq)⟶Cu(s)+Fe(C₂H₃O₂)₂(aq) single displacement

Pb(NO3)₂(aq)+2KI(aq)⟶PbI₂(s)+2KNO₃(aq) double displacement and precipitation

2K(s)+2H₂O(l)⟶2KOH(aq)+H₂(g) single displacement

H₂SO4(aq)+Mg(OH)₂(aq)⟶2H₂O(l)+MgSO₄(aq) acid-base neutralization

C₈H₁₆(l)+12O₂(g)⟶8CO₂(g)+16H₂O(g) combustion
