Химия: Продолжить св-ва cao+h2o→ mgo+hcl→ bao+ hcl→ ca(oh)2+co2→ ba(oh)2+hcl→ ca(oh)2+na3po4→ caco3→ cacl2+na2co3→

grenika · Answer

CaO +H2O = Ca(OH)2MgO +2HCl = MgCl2 +H2OBaO +2HCl = BaCl2 + H2OCa(OH)2 +CO2 = CaCO3 +H2OBa(OH)2 + 2HCl = BaCl2 + 2H2O3Ca(OH)2 +2Na3PO4 = Ca3(PO4)2 +6NaOHCaCO3 = CaO + CO2CaCl2 +Na2CO3 = CaCO3 + 2NaCl...
