Question

Stabiliti coeficientii următoarelor reactii chimice:

1. HCl + AgNO3 = HNO3 + AgCl o sageata in jos
2. FeCl3 + NaOH –> Fe(OH)3 + NaCl
3. KClO3 –> KCl + O2
4. Fe + HCl –> FeCl2 + H2
5. Ca(OH)2 + CO2 –> CaCO3 + H2O
6. Al + HCl –> AlCl3 + H2 o sageata in sus

Answer 1

1. HCl+AgNO3->AgCl+HNO3
2.FeCl3+3NaOH->Fe(OH)3+3NaCl
3.2KClO3->2KCl+3O2
4.Fe+2HCl->FeCl2+H2
5. Ca(OH)2+ CO2->CaCO3+H2O
6. 2Al+6HCl->2AlCl3+3H2
