Question

Complete Zn + HCL ___________ NA2CO3 + HCl NaHCO3 + HCL NaOH + HCl Cuo + HCl

Answer 1

Zn + 2 H Cl   =>  H2 + Zn Cl2

Na2 CO3 + 2 H Cl  => 2 Na Cl  +  H2O + CO2

Na HCO3 + H Cl   =>  Na Cl  + H2O + CO2

Na OH + H Cl   =>   H2 O + Na Cl

Cu O + 2 H Cl   =>   H2 O + Cu Cl2

Answer 2

Zn + 2HCl = H₂ + ZnCl₂

Na₂CO₃ + 2HCl = 2NaCl + H₂O + CO₂

NaHCO₃ + HCl = NaCl  + H₂O + CO₂

NaOH + HCl = H₂O + NaCl

CuO + 2HCl = H₂O + CuCl₂

Thanks!
