Question

Помогите расписать в ионном уравнении: CuO+H2SO4= Al2O3+HCL= K2O+H3PO4= Ca(OH)2+HCL= AgNO3+HCL= BaCL2+H2SO4= CaCO3+HCL= За ранее большое спасибо:)

Answer 1

  CuO + H2SO4 = CuSO4 + H2O

CuO + 2H+ + SO42− = Cu2+ + SO42− + H2O

CuO + 2H+ = Cu2+ + H2O  

 

Al2O3 + 6HCl = 2AlCl3 + 3H2O

Al2O3 + 6H+ + 6Cl− = 2Al2+ + 3Cl− + 3H2O

Al2O3 + 6H+ + 3Cl− = 2Al2+ + 3H2O  

 

3K2O + 2H3PO4 = 2 K3PO4 + 3H2O 

 

Ca(OH)2 + 2HCl = CaCl2 + 2H2O

Ca2+ + 2OH− + 2H+ + 2Cl− = Ca2+ + 2Cl− + 2H2O

OH− + H+ = H2O    

 

HCl + AgNO3 = AgCl↓ + HNO3

H+ + Cl− + Ag+ + NO3− = AgCl +H(+)+NO3(-)

Cl− + Ag+  = AgCl

 

BaCl2+ H2SO4 = BaSO4↓ + 2HCl↑    

 

 CaCO3 + 2HCl= CaCl2 + CO2↑ + H2O

CaCO3 + 2H+ + 2Cl− = Ca2+ + 2Cl− + CO2↑ + H2O

CaCO3 + 2H+ = Ca2+ + CO2↑ + H2O

Ion Equations:

1. CuO + H2SO4 = CuSO4 + H2O - Copper(II) oxide reacts with sulfuric acid to form copper(II) sulfate and water [[1]].

2. Al2O3 + HCl = AlCl3 + H2O - Aluminum oxide reacts with hydrochloric acid to form aluminum chloride and water [[2]].

3. K2O + H3PO4 = K3PO4 + H2O - Potassium oxide reacts with phosphoric acid to form potassium phosphate and water [[3]].

4. Ca(OH)2 + HCl = CaCl2 + H2O - Calcium hydroxide reacts with hydrochloric acid to form calcium chloride and water [[4]].

5. AgNO3 + HCl = AgCl + HNO3 - Silver nitrate reacts with hydrochloric acid to form silver chloride and nitric acid [[5]].

6. BaCl2 + H2SO4 = BaSO4 + 2HCl - Barium chloride reacts with sulfuric acid to form barium sulfate and hydrochloric acid [[6]].

7. CaCO3 + 2HCl = CaCl2 + CO2 + H2O - Calcium carbonate reacts with hydrochloric acid to form calcium chloride, carbon dioxide, and water [[7]].
