Question

Химия: 1)al-alcl3-al(oh)3-al2o3-al 2)h2so4-cuso4-cucl2-cu(oh)2-cuo-cu 3)p-ph3-p2o5-h3po4-na3po4

School957 · Answer

2Al + 3Cl2 = 2AlCl3AlCl3 + 3KOH = Al(OH)3 + 3KCl2Al(OH)3 = Al2O3 + 3H2O2Al2O3 = 4Al + 3O2H2SO4 + CuO = CuSO4 + H2OCuSO4 + 2HCl = CuCl2 + H2SO4 CuCl2 + 2NaOH = Cu(OH)2 + 2NaClCu(OH)2 = CuO + H2OCuO = Cu + O2 Фосфин нельзя получить прямым путём : K3P + 3 H2O = 3 KOH + PH3 2РН3+4O2 = P2O5+3Н2O P2O5+3Н2O = 2H3PO4 H3PO4 + 3NaOH = Na3PO4 + 3H2O...
