Question

2. Se da urmatorul sir de substante chimice: Mg, Ca(OH)2, ZnO,CuCO3, Al, Fe(OH)3, AgNO3,ZnS. Scrieti ecuatile chimice ale substantelor cu HCl​

Answer 1

Mg+2HCl->MgCl2+H2 degaja

Ca(OH)2+2HCl->CaCl2+2H2O

ZnO+2HCl->ZnCl2+H2O

2Al+6HCl->2AlCl3+3H2 degaja

Fe(OH)3+3HCl->FeCl3+3H2O

AgNO3+HCl->AgCl+HNO3

CuCO3+2HCl->CuCl2+CO2+H2 degaja

ZnS+2HCl->ZnCl2+H2S

Bafta!
