Va rog frumos urgent
Dau coroana celui mai bun raspuns

Answer 1

a) 2HCl + FeS = FeCl₂ + H₂S

2H⁺Cl⁻ + Fe⁺²S⁻² = Fe⁺²Cl₂⁻¹ + H₂⁺¹S⁻²

b) 2HNO₃ + CaCO₃ = Ca(NO₃)₂↓ + CO₂↑ + H₂O

2H⁺NO₃⁻ + Ca⁺²C⁺⁴O₃⁻² = Ca⁺²(N⁺⁴O₃⁻²)₂⁻¹ + H₂⁺¹O⁻² + C⁺⁴O₂⁻²

c) 2HCl + BaCO₃ = BaCl₂ + CO₂ + H₂O 

2H⁺Cl⁻ + Ba⁺²C⁺⁴O₃⁻² = Ba⁺²Cl₂⁻¹....

d) H₂SO₄ + MgCO₃ = MgSO₄ + CO₂ + H₂O

H₂⁺¹S⁺⁶O₄⁻² + Mg⁺²C⁺⁴O₃⁻² = Mg⁺²S⁺⁶O₄⁻²....

e) 2HNO₃ + PbSO₃ = Pb(NO₃)₂ + H₂SO₄

2H⁺N⁺⁵O₃⁻² + Pb⁺²S⁺⁶O₃⁻² = Pb⁺²(N⁺⁴O₃⁻²)₂⁻¹ + H₂⁺¹S⁺⁶O₄⁻²
