REAKCJE METALI Z KWASAMI:
Zad. Otrzymaj dwoma metodami: siarczan VI sodu, chlorek cynku, azotan V magnezu.
Na2So4-siarczan VI soduH2SO4+2Na->Na2So4+H2Na2O+H2SO4->Na2SO4+H2OZnCl2-chlorek cynkuZn+2HCl->ZnCl2+H2ZnO+2HCl->ZnCl2+H2OMg(NO3)2Mg+2HNO3->Mg(NO3)2+H2MgO+2HNO3->Mg(NO3)2+H2O
Siarczan sodu -
2NaOH + H2SO4 -> Na2SO4 + 2H2O
Na2O + H2SO3 -> Na2SO4 + H2
Chlorek Cynku-
Zn + Cl_2 ---->ZnCl_2
Zn + 2HCl ----> ZnCl_2 + H_2O
Azotan V Magenezu
1. Mg(OH)2+2HNO3-=Mg(NO3)2+2H2O
2)Mg+2HNO3= Mg(NO3)2+H2
3)MgO+N2O5= Mg(NO3)2
