Question

Ca3(PO4)2->

ZnCL2+NaOH->

Na2O+H2O->

AL+HCL->

CaCO3+HCL->

AL2(SO4)3+KOH->

Answer 1

Ca3(PO4)2 = 3CaO + P2O5

ZnCl2 + 2NaOH = Zn(OH)2 (осадок, стрелка вниз) + 2NaCl

Na2O + H2O = 2NaOH

2Al + 6HCl = 2AlCl3 + 3H2

CaCO3 + 2HCl = CaCl2 + H2O + CO2

AL2(SO4)3 + 6KOH = 3K2SO4 + 2Al(OH)3 (осадок, стрелка вниз)
