Question

Дополнить и запасать полное и краткое ионное уравнения:HNO3+ PbS-...; HNO3+Fe(OH)3-...; HNO3+K2CO3-...(заранее спасибо).

Answer 1

1) 2HNO3+PbS=Pb(NO3)2+H2S

2H(+) + 2NO3(-) + Pb(2+) + S(2-) = Pb(2+) + 2NO3(-) + 2H(+) + S(2-)
краткого нет.
2) 3HNO3+Fe(OH)3=Fe(NO3)3+3H2O

3H(+) + 3NO3(-) + Fe(3+) + 3OH(-) = Fe(3+) + 3NO3(-) + 3H2O
краткое: 3H(+) + 3OH(-) = 3H2O
3) 2HNO3+K2CO3=2KNO3+H2O+CO2

2H(+) + 2NO3(-) + 2K(+) + CO3(2-) = 2K(+) + 2NO3(-) + H2O + CO2
краткое: 2H(+) + CO3(2-) = H2O + CO2

Balancing Chemical Equations with Nitric Acid (HNO3)

When balancing chemical equations involving nitric acid (HNO3), it's important to consider the reaction and the products formed. Let's balance the given chemical equations step by step.

HNO3 + PbS

The balanced ionic equation for the reaction between nitric acid (HNO3) and lead(II) sulfide (PbS) is as follows:

Complete Ionic Equation: 2H⁺(aq) + 2NO3⁻(aq) + Pb²⁺(aq) + S²⁻(aq) → Pb²⁺(aq) + 2NO3⁻(aq) + H2O(l) + SO2(g)

Net Ionic Equation: 2H⁺(aq) + S²⁻(aq) → H2O(l) + SO2(g)

HNO3 + Fe(OH)3

The balanced ionic equation for the reaction between nitric acid (HNO3) and iron(III) hydroxide (Fe(OH)3) is as follows:

Complete Ionic Equation: 3H⁺(aq) + 3NO3⁻(aq) + Fe³⁺(aq) + 3OH⁻(aq) → Fe³⁺(aq) + 3NO3⁻(aq) + 3H2O(l)

Net Ionic Equation: 3H⁺(aq) + 3OH⁻(aq) → 3H2O(l)

HNO3 + K2CO3

The balanced ionic equation for the reaction between nitric acid (HNO3) and potassium carbonate (K2CO3) is as follows:

Complete Ionic Equation: 2H⁺(aq) + 2NO3⁻(aq) + 2K⁺(aq) + CO3²⁻(aq) → 2K⁺(aq) + 2NO3⁻(aq) + H2O(l) + CO2(g)

Net Ionic Equation: 2H⁺(aq) + CO3²⁻(aq) → H2O(l) + CO2(g)
