Составить уравнения реакций и расставить коэффициенты 1) P2O5 + CaO = 2) Bao + HNO3 = 3) Al2O + HCl = 4) SO2 + Bao (OH) 2 = 5) BaCl2 + H2SO4 = 6) KOH + H3PO4 = 7) KOH + N2O5 = 8) KOH + CuCl2 = 9) Cu (OH) + HCl = 10) Fe (OH) 3 = 11) Zn + HCl =

Расставьте коэффициенты и определите тип следующих реакций: Ba + O2 = BaO; C3H8 + O2 = CO2 + H2O Na + O2 = Na2O; Al (OH) 3 + HCl = AlCl3 + H2O Al + O2 = Al2O3; NaOH + H3PO4 = Na3PO4 + H2O K + Cl2 = KCl;

Na + HCl = Al + HCl = Ca + H3PO4 = MgO + H3PO4 = Zn + HCl = Mg + H2SO4 = Fe (OH) 3 + HCl = CaO + HCl = Fe2O3 + H2SO4 = MgO + H3PO4 = Cu + HCl = H3PO4 + H2SO4 NaCl + HNO3
