Объяснение:
6.
1) 2Na + 2HCl = 2NaCl + H2
2) 2Na + H2SO4 = Na2SO4 + H2
3) 2K + 2HCl = 2KCl + H2
4) Ca + 2HCl = CaCl2 + H2
5) 2Аl + 6HCl = 2AlCl3 + 3H2
6) Zn + 2HCl = ZnCl2 + H2
7.
Ca + 2HBr = CaBr2 + H2
Au + HBr = реакция не идет
6Na + 2H3PO4 = 2Na3PO4 + 3H2
Ag + HCl = реакция не идет
Zn + 2HI = ZnI2 + H2
