Answer 2

Reaction between Magnesium Chloride and Calcium Nitrate

The reaction between magnesium chloride (MgCl2) and calcium nitrate (Ca(NO3)2) in solution can be represented by the following molecular and ionic equations:

Molecular Equation: MgCl2(aq) + Ca(NO3)2(aq) → Mg(NO3)2(aq) + CaCl2(aq)

Ionic Equation: Mg^2+(aq) + 2Cl^-(aq) + Ca^2+(aq) + 2NO3^-(aq) → Mg^2+(aq) + 2NO3^-(aq) + Ca^2+(aq) + 2Cl^-(aq)

The reaction occurs in an aqueous solution, meaning that both magnesium chloride and calcium nitrate are dissolved in water.

Reaction between Magnesium Sulfate and Barium Nitrate

The reaction between magnesium sulfate (MgSO4) and barium nitrate (Ba(NO3)2) in solution can be represented by the following molecular and ionic equations:

Molecular Equation: MgSO4(aq) + Ba(NO3)2(aq) → Mg(NO3)2(aq) + BaSO4(s)

Ionic Equation: Mg^2+(aq) + SO4^2-(aq) + Ba^2+(aq) + 2NO3^-(aq) → Mg^2+(aq) + 2NO3^-(aq) + BaSO4(s)

The reaction occurs in an aqueous solution, meaning that both magnesium sulfate and barium nitrate are dissolved in water.

Reaction between Iron (III) Chloride and Orthophosphoric Acid

The reaction between iron (III) chloride (FeCl3) and orthophosphoric acid (H3PO4) can be represented by the following molecular and ionic equations:

Molecular Equation: FeCl3(aq) + H3PO4(aq) → FePO4(s) + 3HCl(aq)

Ionic Equation: Fe^3+(aq) + 3Cl^-(aq) + 3H3PO4(aq) → FePO4(s) + 9H^+(aq) + 3Cl^-(aq)

The reaction occurs in an aqueous solution, meaning that both iron (III) chloride and orthophosphoric acid are dissolved in water.

Please note that the given equations represent the overall reaction. The actual reaction may involve intermediate steps or side reactions, but these equations provide a simplified representation of the main chemical changes that occur.
