Question

!!! ЛЁГКИЙ ВОПРОС !!! Скласти молекулярні та повні йонні рівняння реакцій, які відповідають таким йонно – молекулярним. 1. H+ + OH- → H2O 2. CaCO3 + 2H+ → Ca2+ + CO2 + H2O

Answer 1

Ответ:

Объяснение:

1) KOH+HNO₃=KNO₃+H₂O

K⁺+OH⁻+H⁺+NO₃⁻=K⁺+NO₃⁻+H₂O

OH⁻+H⁺=H₂O

2) CaCO3 + H₂SO₄ = CaSO₄ + CO₂↑ + H₂O

CaCО₃ + 2H⁺ + SO₄²⁻ = Ca²⁺ + SO₄²⁻ + CO₂↑ + H₂O

CaCO₃ + 2H⁺ = Ca²⁺ + CO₂↑ + H₂O

Answer 2

Molecular and Ionic Equations for the Given Reactions

1. The reaction: H+ + OH- → H2O

To write the molecular equation, we start with the reactants and write them as they are:

H+ + OH- → H2O

To write the ionic equation, we need to break down the reactants and products into their respective ions:

H+ + OH- → H2O

Now, let's balance the equation by ensuring that the number of atoms of each element is the same on both sides:

2H+ + 2OH- → 2H2O

The balanced molecular equation is: 2H+ + 2OH- → 2H2O

The balanced ionic equation is: 2H+ + 2OH- → 2H2O

2. The reaction: CaCO3 + 2H+ → Ca2+ + CO2 + H2O

To write the molecular equation, we start with the reactants and write them as they are:

CaCO3 + 2H+ → Ca2+ + CO2 + H2O

To write the ionic equation, we need to break down the reactants and products into their respective ions:

CaCO3 + 2H+ → Ca2+ + CO2 + H2O

Now, let's balance the equation by ensuring that the number of atoms of each element is the same on both sides:

CaCO3 + 2H+ → Ca2+ + CO2 + H2O

The balanced molecular equation is: CaCO3 + 2H+ → Ca2+ + CO2 + H2O

The balanced ionic equation is: CaCO3 + 2H+ → Ca2+ + CO2 + H2O

Please note that the above equations are simplified representations of the reactions and may not include all the details.
