CuSO4(aq) + BaCl2(aq) -> CuCl2(aq) + BaSO4(s)
(NH4)2SO4(aq) + BaCl2(aq) → 2NH4Cl(aq) + BaSO4(s). Barium sulfate is the precipitate.
If an aqueous solution of copper(II) sulfate is contacted with metallic iron, at the least the surface of the iron passes into solution and is replaced by a layer of metallic copper. This is an example of displacement by a metal higher in the electromotive series than the metal it displaces.
The balanced chemical equation for this reaction is: 2HCl(aq) + Ba(OH)2(aq) → BaCl2(aq) + 2H2O(l). This is a double displacement reaction where barium hydroxide reacts with hydrochloric acid to form barium chloride and water.
Heating a crystal of blue copper sulfate typically results in the release of water vapor, leaving behind white anhydrous copper sulfate powder. The black powder formed may be due to decomposition of the copper sulfate or impurities in the crystal. Sulfur may not be directly produced from heating copper sulfate.
When silver nitrate and ferrous sulfate are mixed, a white precipitate of silver sulfate forms due to the double displacement reaction between silver and sulfate ions. The iron ions from ferrous sulfate remain in solution.
(NH4)2SO4(aq) + BaCl2(aq) → 2NH4Cl(aq) + BaSO4(s). Barium sulfate is the precipitate.
This word equation is incorrect because it does not follow the law of conservation of mass. The equation should be: calcium chloride plus magnesium sulfate yields barium sulfate plus magnesium chloride.
Ooh. Somebody doesn't like doing their chem homework. Luckily I just happened to do that exact same equation. 1 BaCl2 +1 Na2S --> 2 NaCl(Salt! :D) +1 BaS
barium chloride plus sodium sulphate yields barium sulphate plus sodium chloride
Sulfuric acid plus copper (II) nitrate yields nitric acid plus copper (II) sulfate. Sulfuric acid plus copper (I) nitrate yields nitrous acid plus copper (I) sulfate.
The word equation for Cu + H2SO4 is copper + sulfuric acid yields copper(II) sulfate + hydrogen gas.
This is called a reduction / oxidation reaction:Reduction of Cu2+ to Cu , done by electron donation from Zn which is then oxidized to Zn2+.Sulfate ions (SO42-) do not take part in this, they're called: tribuned ions.

Pb(NO3)2 + CuSO4 -> PbSO4 + Cu(NO3)2
CuSO4 Cu + 2H2SO4 -> CuSO4 + SO2 + 2H2O
