Question

Напишите химические цепочки уравнения: Ca=CaO=Ca(OH)2=CaCl2=CaCO3=CaO=Ca3(PO4)2

Answer 1

Ca + O2 = 2CaO
CaO + H2O = Ca(OH)2
Ca(OH)2 + 2HCl =CaCl2 + 2H2O
CaCl2 + Na2CO3 = CaCO3↓ + 2NaCl
CaCO3=(температура) CaO + CO2
3CaO + 2H3PO4  = Ca3(PO4)2 + 3H2O

Answer 2

Chemical Equations:

The chemical equations for the given compounds are as follows:

1. Calcium (Ca): Ca 2. Calcium Oxide (CaO): Ca + O2 → CaO3. Calcium Hydroxide (Ca(OH)2): CaO + H2O → Ca(OH)2 [[1]](https://uchi.ru/otvety/questions/reshite-tsepochku-prevrascheniy-ca-ca-oh-2-caco3-cao-cacl2-ca-t-bao-ba-oh-2-ba-no3-2-nano) 4. Calcium Chloride (CaCl2): Ca(OH)2 + 2HCl → CaCl2 + 2H2O [[1]](https://uchi.ru/otvety/questions/reshite-tsepochku-prevrascheniy-ca-ca-oh-2-caco3-cao-cacl2-ca-t-bao-ba-oh-2-ba-no3-2-nano) 5. Calcium Carbonate (CaCO3): CaO + CO2 → CaCO36. Calcium Oxide (CaO): CaCO3 → CaO + CO27. Calcium Phosphate (Ca3(PO4)2): 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O [[2]](https://mzz.misis.ru/wp-content/uploads/2015/09/Himiya_3_vyvod.pdf)
