None of the materials listed is a heavy metal, because most of them are compounds, and only elements are ever heavy metals. The only one on the list that does not contain a heavy metal is chlorine, which is a nonmetallic element.
Copper sulfate + lead nitrate = Copper nitrate + Lead sulfate CuSO4 (aq) + Pb(NO3)2 (aq) = Cu(NO3)2 (aq) + PbSO4 (s)
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
Ammonium sulfate reacts with barium nitrate to form ammonium nitrate and barium sulfate. (NH4)2SO4 + Ba(NO3)2 ==> 2NH4NO3 + BaSO4 It is a double replacement reaction. that is the correct answer
With x being lead nitrate, and b copper sulfate. a=atoms, and c=carbon.
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
The lead nitrate and sodium sulfate precipitate together and becomes lead sulfate and sodium nitrate. lead nitrate+ sodium sulfate --> lead sulfate + sodium nitrate
Lead nitrate + potassium sulfate ---> Lead sulfate + Potassium nitrate
Copper sulfate + lead nitrate = Copper nitrate + Lead sulfate CuSO4 (aq) + Pb(NO3)2 (aq) = Cu(NO3)2 (aq) + PbSO4 (s)
If the sodium sulfate and barium nitrate are both in solution in water, a precipitate of barium sulfate will be formed, because this salt is much less soluble in water than barium nitrate, sodium sulfate, or sodium nitrate.
Ammonium sulfate reacts with barium nitrate to form ammonium nitrate and barium sulfate. (NH4)2SO4 + Ba(NO3)2 ==> 2NH4NO3 + BaSO4 It is a double replacement reaction. that is the correct answer
With x being lead nitrate, and b copper sulfate. a=atoms, and c=carbon.
No reaction will occur between Potassium Sulfate and Ammonium Nitrate.
The products of the reaction are solid calcium sulfate and aqueous lithium nitrate.
Magnesium nitrate (MgNO3) is a nitrogen source. Magnesium sulfate (MgSO4) is a sulfur source.
Hydrated sodium, sulfate, silver, and nitrate ions. (The ions already exist in the sodium sulfate and silver nitrate solids, but may not be hydrated there.) since silver sulfate is not very soluble in water, most of the silver and sulfate ions will be removed from the water as solid precipitate, but some hydrated ions will remain in solution.
Lead Chromate and Ammonium Sulfate by a double-replacement reaction.
One contains sulfate ions and the other contains nitrate ions. This changes many of the physical and chemical properties of the compounds.
