Question

Ca--->CaO------>Ca(OH)2----->CaSO4---->CaCl2---->Ca(NO3)2--->Ca3(PO4)2---->CaCO3
решите

Answer 1

2Сa + O2 = 2caO
CaO + H2O = Ca(OH)2
Ca(OH)2 + H2SO4 = CaSO4 + 2H2O
CaSO4 + BaCl2 = CaCl2 + BaSO4
CaCl2 + 2AgNO3 = Ca(NO3)2 + 2AgCl
3Ca(NO3)2 + 2K3PO4 = Ca3(PO4)2  + 6KNo3
Ca3(PO4)2 + 3Na2CO3 = 3CaCO3 + 2Na3Po4
