rinkisa 1.Si--SiO2--Na2SiO3--H2SiO3--SiO2--Si.1) Si + O₂=(при t)= SiO₂2) SiO₂ + 2NaOH = Na₂SiO₃ + H₂3) Na₂SiO₃ + 2HCl = 2NaCl + H₂SiO₃↓4) H₂SiO₃ =(при хранении)= SiO₂ + H₂O5) SiO₂ + 2Mg = 2MgO + Si 2. P--P2O5--H3PO4--Na3PO4.1) 4P + 5O₂( избыт) =(при t)= 2P₂O₅2) P₂O₅ + 3H₂O = 2H₃PO₄3) H₃PO₄ + 3NaOH = Na₃PO₄ + 3H₂O 3.CuO--CuCl2--Cu(OH)2--CuO-->Cu1)2)3) Cu(OH)₂ =(при t)= CuO + H₂O4)CuO + CO = Cu + CO₂↑ 4. K--K2O--KOH—KCl1) 4K + O₂ = 2K₂O2)3)KOH + HCl = KCl + H₂O
