Write down the molecular and ionic equations of the reactions between: a) Barium nitrate and sulfuric acid. b) Copper nitrate

Write down the molecular and ionic equations of the reactions between: a) Barium nitrate and sulfuric acid. b) Copper nitrate (2) and sodium hydroxide c) Silver nitrate and sodium chloride d) Copper sulfate (2) and iron shavings

1) The reaction takes place between substances such as sodium nitrate salt and sulfuric acid. As a result of this chemical interaction, the barium sulfate salt and nitric acid are formed. This is an exchange reaction.

Ba (NO3) 2 + H2SO4 = BaSO4 + 2 HNO3

The ionic reaction equation can be written as follows:

Ba²⁺ + 2 NO₃ ^–  + 2 H ⁺ + SO₄ ^2-  = BaSO₄ + 2 H⁺ + 2 NO₃^–

Ba ²⁺ + SO₄ ^2- = BaSO_4.

2) Copper nitrate salt reacts with sodium hydroxide. Divalent copper hydroxide and sodium nitrate salt are formed. This reaction also proceeds according to the type of exchange.

Cu (NO3) 2 +2 NaOH = Cu (OH) 2 + 2 NaNO3

The ionic reaction equation can be written as follows:

Cu ²⁺ + 2 NO₃^–  + 2 Na ⁺ + 2 OH ^– = Cu(OH)₂ + 2 Na ⁺ + 2 NO₃ ^–

Cu ²⁺ + 2 OH ^– = Cu(OH)₂

3) The silver nitrate salt enters into a chemical exchange reaction with the sodium chloride salt and form the sodium nitrate salt and the silver chloride salt, which precipitates.

AgNO3 + NaCl = AgCl + NaNO3

The ionic reaction equation can be written as follows:

Ag⁺  + NO₃ ^– + Na ⁺ + Cl ^– = AgCl + Na⁺  + NO₃^–

Ag ⁺ + Cl ^– = AgCl

4) Salt copper sulfate interacts with iron. After passing through a chemical reaction, ferrous sulfate salt and pure copper are formed. This is an exchange reaction.

CuSO4 + Fe = FeSO4 + Cu

The ionic reaction equation can be written as follows:

Cu ²⁺ + SO₄ ^2- + Fe = Fe ²⁺ + SO₄ ^2- + Cu

Cu ²⁺ + Fe = Fe ²⁺ + Cu.
