Химия: Cu(no3)2→o2→p2o5→ba(h2po4)2→bahpo4→ba3(po4)2→h3po4→cahpo4→ca(h2po4)2→caso4

darkelan · Answer

Cu(NO3)2=2CuO+4NO2+O25O2+4P=2P2O5Ba(OH)2 + P2O5 + H2O = Ba(H2PO4)2Ba(H2PO4)2 + Ba(OH)2 = 2BaHPO4 + 2H2O2BaHPO4+Ba(OH)2=Ba3(PO4)2+2H2OBa3(PO4)2+3H2SO4=2H3PO4+3BaSO4H3PO4+Ca(OH)2=CaHPO4+2H2OCaHPO4+Ca(OH)2=2Ca(H2PO4)2+2H2OCa(H2PO4)2+2H2SO4=2CaSO4+2H3PO4 ...
