Chemical Equations

aluminum is combined with lead(II) nitrate

2 Al(s) + 3Pb(NO3)2(aq) → 3Pb(s) + 2Al(NO3)3(aq) net ionic: 2Al + 3Pb2+ → 3Pb + 2Al3+

Rubidium chlorate decomposes upon heating

2 RbClO3(aq) → 2RbCl(s) + 3O2(g)

Sodium hydroxide is combined with weak carbonic acid

2NaOH(aq) + H2CO3(aq) → Na2CO3(aq) + 2H2O(L) Net Ionic: 2 OH−(aq) + H2CO3(aq) → 2H2O(L) + CO32−

nickel metal is dropped into tin(II) acetate [if a Rx occurs, assume nickel(III) forms]

2Ni(s) + 3Sn(C2H3O2)2(aq) → 3Sn(s) + 2Ni(C2H3O2)3(aq) net ionic: 2Ni + 3Sn2+ → 3Sn + 2Ni3+

lead(II) nitrate is combined with aluminum chloride

3Pb(NO3)2(aq) + 2AlCl3(aq) → 2Al (NO3)3(aq) + 3PbCl2(s)

silver nitrate is combined with sodium bromide

Ag(NO3)2 + 2NaBr → 2NaNO3 + AgBr2

Barium hydroxide is combined with hydrochloric acid

Ba(OH)2(aq) + 2HCl(aq) → BaCl2 + 2H2O(L)

Calcium hydroxide is combined with weak carbonic acid

Ca(OH)2(aq) + H2CO3(aq) → CaCO3(ppt)+ 2H2O(L) Net Ionic: Ca(OH)2 (aq) + H2CO3(aq) → CaCO3(ppt) + 2 H2O(L)

Magnesium chloride and oxygen gas react

MgCl2(s) + 3O2(g) → Mg(ClO3)2(s)

Aqueous nitric acid is the product of the combination of gaseous dinitrogen pentoxide and water.

N2O5(g) + H2O(L) → 2HNO3(aq)

Sodium hydroxide is combined with hydrochloric acid

NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(L)

Nickel(II) chlorate decomposes when heated

Ni(ClO3)2(aq) → NiCl2(s) + 3O2(g)

Solid diphosphorus pentoxide combine with liquid water to produce aqueous phosphoric acid (one of those six acids you have been asked to memorize.)

P2O5(s) + 3H2O(L) → 2H3PO4

Radium fluoride decomposes upon heating.

RaF2(s) → Ra(s) + F2(g)

iron is dropped into lead(IV) sulfate [if a Rx occurs, assume iron(III) forms]

lead(IV) sulfate is not soluble therefore no replacement can occur = NR

ammonium carbonate is combined with lithium sulfate

(NH4)2SO4(aq) + Mg3(PO4)2(s) → no reaction, one is a solid
