Question

Ecuatiile reactiilor chimice (EM,EIC,EIR)

H2SO4 + 2 NaCl = 2 HCl + Na2SO4

H2SO4 + Fe = FeSO4 + H2

H2SO4 + Zn = H2 + ZnSO4

Answer 1

H2⁺SO4²⁻ + 2Na⁺Cl⁻---> HC↑ + Na2⁺SO4²⁻

H⁺+Cl⁻⁻----> HCl↑

H2⁺SO4²⁻ +Fe---> Fe²⁺So4²⁻ + H2↑

2H⁺ + Fe---> Fe²⁺+H2↑

H2⁺SO4²⁻ +Zn---> Zn²⁺SO4²⁻ + H2↑

2H⁺+Zn---> Zn²⁺ +H2↑
