Question

Na2CO3 + 2HCI = 2NaCI + H2O + CO2↑H2SO4 + BaCI2 = 2HCI + BaSO4↓​

Answer 1

Ответ:

Объяснение:

Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂↑

2Na⁺ + CO₃²⁻ + 2H⁺ + 2Cl⁻ → 2Na⁺ + 2Cl⁻ + H₂O + CO₂↑

CO₃²⁻ + 2H⁺ → H₂O + CO₂↑

BaCl₂ + H₂SO₄ = BaSO₄↓ + 2HCl

Ba²⁺ + 2Cl⁻ + 2H⁺ + SO₄²⁻ = BaSO₄↓ + 2H⁺ + 2Cl⁻

Ba²⁺ + SO₄²⁻= BaSO₄↓

Answer 2

The chemical equations you provided are balanced equations representing chemical reactions. Let's break them down:

1. Na2CO3 + 2HCl → 2NaCl + H2O + CO2↑

This equation represents the reaction between sodium carbonate (Na2CO3) and hydrochloric acid (HCl). It produces sodium chloride (NaCl), water (H2O), and carbon dioxide gas (CO2) as products.

2. H2SO4 + BaCl2 → 2HCl + BaSO4↓

This equation represents the reaction between sulfuric acid (H2SO4) and barium chloride (BaCl2). It produces hydrochloric acid (HCl) and a precipitate of barium sulfate (BaSO4) as products.

In both equations, the numbers in front of the chemical formulas indicate the stoichiometric coefficients, which ensure that the number of atoms of each element is balanced on both sides of the equation.
