Question

ZnO + H3PO4 = Fe2O3 + HCl = BeO + KOH = ZnO + Li2O = Al(OH)3 + H2SO4 = Sn(OH)2 + KOH = Sn(OH)2 + Cu(OH)2 = Sn(OH)2 + MgO = Реакції обов'язково врівняти і вказати тип реакці

Answer 1

Ответ:

3ZnO + 2 H3PO4 =Zn3(PO4)2 + 3H2O ( кислотно лужна реакція/ реакція обміну)

Fe2O3 + 6HCl =2FeCl3 + 3H2O(реакція обміну)

BeO + 2KOH =K2BeO2 + H2O (реакція обміну)

ZnO + Li2O =Li2ZnO2(синтез)

2Al(OH)3 + 3 H2SO4 =Al2(SO4)3 + 6 H2O ( реакція обміну)

Sn(OH)2 +2 KOH =K2SnO2 + 2H2O( реакція обміну)

Sn(OH)2 + Cu(OH)2 = не реагують

Sn(OH)2 + 2MgO =2Mg(OH)2 + SnO2( реакція обміну)

Chemical Reactions and Balancing Equations

Let's analyze the given chemical reactions and balance the equations. Here are the reactions along with their balanced equations and reaction types:

1. ZnO + H3PO4 → Zn3(PO4)2 + H2O - Balanced equation: ZnO + 2H3PO4 → Zn3(PO4)2 + 3H2O - Reaction type: Double displacement reaction

2. Fe2O3 + 6HCl → 2FeCl3 + 3H2O - Balanced equation: Fe2O3 + 6HCl → 2FeCl3 + 3H2O - Reaction type: Double displacement reaction

3. BeO + 2KOH → K2BeO2 + H2O - Balanced equation: BeO + 2KOH → K2BeO2 + H2O - Reaction type: Double displacement reaction

4. ZnO + Li2O → Li2ZnO2 - Balanced equation: ZnO + Li2O → Li2ZnO2 - Reaction type: Double displacement reaction

5. Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 6H2O - Balanced equation: 2Al(OH)3 + 3H2SO4 → Al2(SO4)3 + 6H2O - Reaction type: Double displacement reaction

6. Sn(OH)2 + 2KOH → K2SnO2 + 2H2O - Balanced equation: Sn(OH)2 + 2KOH → K2SnO2 + 2H2O - Reaction type: Double displacement reaction

7. Sn(OH)2 + Cu(OH)2 → Sn(OH)2 + CuO + H2O - Balanced equation: Sn(OH)2 + Cu(OH)2 → SnO + CuO + 2H2O - Reaction type: Double displacement reaction

8. Sn(OH)2 + MgO → SnO + Mg(OH)2 - Balanced equation: Sn(OH)2 + MgO → SnO + Mg(OH)2 - Reaction type: Double displacement reaction

In all the given reactions, the reaction type is double displacement. Double displacement reactions occur when the positive ions of two compounds exchange places to form new compounds. The balanced equations show the stoichiometric coefficients required to balance the number of atoms on both sides of the equation.
