BaSO_4+2H_2O\\2HCl+Ca(OH)_2=>CaCl_2+2H_2O\\2H_3PO_4+2Al=>2AlPO_4+3H_2\uparrow\\H_2SO_3+Zn=>ZnSO_3+H_2\uparrow" alt="H_2SO_4+Ba(OH)_2=>BaSO_4+2H_2O\\2HCl+Ca(OH)_2=>CaCl_2+2H_2O\\2H_3PO_4+2Al=>2AlPO_4+3H_2\uparrow\\H_2SO_3+Zn=>ZnSO_3+H_2\uparrow" align="absmiddle" class="latex-formula">

Answer 2

Ba(OH)2 + H2SO4(разб.) = BaSO4↓ + 2H2OCaCl2 + 2H2O(пар) = Ca(OH)2 + 2HCl 2H3PO4+2Al=2AlPO4+3H2 H2SO3+Zn=ZnSO3+H2
