Question

CaCl2>HCl> AlCl3>HCl

2) составьте уравнениЯ реакций Hcl, FeOH(3) , MgSO4

Answer 1

CaSO4 +2HCl -> CaCl2 + H2SO4
CaCl2+ 2HBr -> CaBr2+ 2HCl
6HCl+ 2Al -> 2AlCl3+ 3H2
2AlCl3+ 3H2CO3-> Al2(CO3)3 + 6HCl

2)
HCl
2 HCl+ Ca-> CaCl2 + H2
HCl+ NaOH-> NaCl + H2O
2HCl + CuO-> CuCl2 + H2O
HCl+ CaCO3-> CaCl2 + H2CO3
