Question

Describe and find the type of reaction. CaCl2 (aq) + 2 AgNO3 (aq) -->Ca(NO3)2 (aq) + 2 AgCl (s)

Answer 1

Ответ:

Объяснение:

СaCl₂ + 2AgNO₃ = Ca(NO₃)₂ + 2AgCl↓

Ca²⁺ + 2Cl⁻ + 2Ag⁺ + 2NO₃⁻ = Ca²⁺ + 2NO₃⁻ + 2AgCl↓

Ag⁺ + Cl⁻ = AgCl↓

Answer 2

The given chemical equation represents a double displacement reaction, also known as a precipitation reaction. In this type of reaction, the ions in the reactants switch places to form new products.

The equation: CaCl₂ (aq) + 2 AgNO₃ (aq) → Ca(NO₃)₂ (aq) + 2 AgCl (s)

In this reaction:

• Calcium chloride (CaCl₂) reacts with silver nitrate (AgNO₃).
• The calcium ions (Ca²⁺) from calcium chloride combine with the nitrate ions (NO₃⁻) from silver nitrate to form calcium nitrate (Ca(NO₃)₂) in the aqueous state.
• Meanwhile, the chloride ions (Cl⁻) from calcium chloride react with the silver ions (Ag⁺) from silver nitrate to form solid silver chloride (AgCl), which precipitates out as a white solid.

The reaction can be summarized as follows: Ca²⁺ + 2 Ag⁺ + 2 Cl⁻ + 2 NO₃⁻ → Ca(NO₃)₂ + 2 AgCl

The type of reaction is a double displacement reaction, specifically a precipitation reaction, because a solid (precipitate) is formed when the two aqueous solutions mix.
