Question

AgNo3 + KCl --> ? идёт до конца? NH4Cl + NaOH --> ? NaNO3 + BaCl2 --> ? FeCl3 + NaOH --> ? Во всех остальных тоже идёт ли реакция до конца?

Answer 1

AgNO3 + KCl = AgCl + KNO3

NH4Cl + NaOH = NH4OH + NaCl

2 NaNO3 + BaCl2 = 2 NaCl + Ba(NO3)2

FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl

Answer 2

До конца идут реакции номер 1 и 4

Answer 3

Chemical Reactions and Equilibrium

When considering the chemical reactions provided, it's important to understand the concept of chemical equilibrium. In a chemical reaction, the equilibrium state is reached when the rate of the forward reaction is equal to the rate of the reverse reaction. At this point, the concentrations of the reactants and products remain constant over time.

AgNO3 + KCl → ?

The reaction between silver nitrate (AgNO3) and potassium chloride (KCl) results in the formation of a precipitate of silver chloride (AgCl) and potassium nitrate (KNO3). This reaction proceeds to completion as silver chloride is insoluble in water, leading to the precipitation of the product. The balanced chemical equation for this reaction is:

2AgNO3 + 2KCl → 2AgCl + 2KNO3

The formation of a solid precipitate indicates that the reaction proceeds to completion [[1]].

NH4Cl + NaOH → ?

The reaction between ammonium chloride (NH4Cl) and sodium hydroxide (NaOH) results in the formation of ammonia gas (NH3), water (H2O), and sodium chloride (NaCl). This reaction also proceeds to completion as ammonia gas is liberated, indicating that the reaction has reached equilibrium. The balanced chemical equation for this reaction is:

NH4Cl + NaOH → NH3 + H2O + NaCl

The liberation of ammonia gas signifies that the reaction proceeds to completion [[2]].

NaNO3 + BaCl2 → ?

The reaction between sodium nitrate (NaNO3) and barium chloride (BaCl2) results in the formation of barium nitrate (Ba(NO3)2) and sodium chloride (NaCl). This reaction also proceeds to completion as barium nitrate is a soluble salt, indicating that the reaction reaches equilibrium. The balanced chemical equation for this reaction is:

NaNO3 + BaCl2 → Ba(NO3)2 + 2NaCl

The formation of a soluble salt indicates that the reaction proceeds to completion [[3]].

FeCl3 + NaOH → ?

The reaction between iron(III) chloride (FeCl3) and sodium hydroxide (NaOH) results in the formation of iron(III) hydroxide (Fe(OH)3) and sodium chloride (NaCl). This reaction also proceeds to completion as iron(III) hydroxide is a precipitate, indicating that the reaction reaches equilibrium. The balanced chemical equation for this reaction is:

FeCl3 + 3NaOH → Fe(OH)3 + 3NaCl

The formation of a solid precipitate indicates that the reaction proceeds to completion [[4]].

In all the provided reactions, the formation of a precipitate or a gas indicates that the reactions proceed to completion, reaching equilibrium.
