Question

Перерешайте, пожалуйста, есть сомнения Реакция ионеого обмена идет до конца в результате образования слабого электролита воды при взаимодействии: 1)BaCl2 c Na2SO4 2)Zn c H2SO4 3) NaOH c H2SO4 4) CaCl2 c Na2CO3

Answer 1

Там где образуется газ осадок или слабый электролит там реакция будет до конца

Answer 2

Reaction 1: BaCl2 + Na2SO4

The reaction between BaCl2 (barium chloride) and Na2SO4 (sodium sulfate) results in the formation of a precipitate called barium sulfate (BaSO4) and a solution of sodium chloride (NaCl).

The balanced chemical equation for this reaction is:

BaCl2 + Na2SO4 -> BaSO4 + 2NaCl

In this reaction, barium chloride reacts with sodium sulfate to produce barium sulfate and sodium chloride.

Reaction 2: Zn + H2SO4

The reaction between zinc (Zn) and sulfuric acid (H2SO4) results in the formation of zinc sulfate (ZnSO4) and hydrogen gas (H2).

The balanced chemical equation for this reaction is:

Zn + H2SO4 -> ZnSO4 + H2

In this reaction, zinc reacts with sulfuric acid to produce zinc sulfate and hydrogen gas.

Reaction 3: NaOH + H2SO4

The reaction between sodium hydroxide (NaOH) and sulfuric acid (H2SO4) results in the formation of sodium sulfate (Na2SO4) and water (H2O).

The balanced chemical equation for this reaction is:

2NaOH + H2SO4 -> Na2SO4 + 2H2O

In this reaction, sodium hydroxide reacts with sulfuric acid to produce sodium sulfate and water.

Reaction 4: CaCl2 + Na2CO3

The reaction between calcium chloride (CaCl2) and sodium carbonate (Na2CO3) results in the formation of calcium carbonate (CaCO3) and a solution of sodium chloride (NaCl).

The balanced chemical equation for this reaction is:

CaCl2 + Na2CO3 -> CaCO3 + 2NaCl

In this reaction, calcium chloride reacts with sodium carbonate to produce calcium carbonate and sodium chloride.
