Question

Закончить уровнения, расставить коэффициенты и назвать образующие вещества.Na2O+H3PO4FeO+H2SO4BaO+HNo3HgO+HCLFe2O3+H2SO4CaO+HClAg2O+HNO3Al2O3+H2SO

Answer 1

NA2O+2H3PO4=2Na3PO4+3H2O

FeO+H2SO4+FeSO4+H2O

BaO+2HNO3=Ba(NO3)2+H2O

HgO+2HCl=HgCl2+H2O

CaO+2HCl=CaCl2+H2O

Ag2O+2HNO3=2AgNO3+H2O

Answer 2

3Na2O+2H3PO4=2Na3PO4+3H2O

FeO+H2SO4=FeSO4 + H2O

BaO+2HNo3=Ba(NO3)2+H2O

2HCl + HgO=H2O+HgCL2

CaO + 2HCl = CaCl2 + H2O

Ag2O+2HNO3=2AgNo3+H2O

Fe2O3 + 3 H2SO4 = Fe2(SO4)3 + 3 H2O

Balancing Equations and Identifying Reactants and Products

To balance the given chemical equations and identify the reactants and products, let's go through each equation one by one:

1. Na2O + H3PO4 → ? - To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. - The balanced equation is: Na2O + 2H3PO4 → 2NaH2PO4 - Reactants: Na2O, H3PO4 - Product: NaH2PO4

2. FeO + H2SO4 → ? - The balanced equation is: FeO + H2SO4 → FeSO4 + H2O - Reactants: FeO, H2SO4 - Products: FeSO4, H2O

3. BaO + HNO3 → ? - The balanced equation is: BaO + 2HNO3 → Ba(NO3)2 + H2O - Reactants: BaO, HNO3 - Products: Ba(NO3)2, H2O

4. HgO + HCl → ? - The balanced equation is: HgO + 2HCl → HgCl2 + H2O - Reactants: HgO, HCl - Products: HgCl2, H2O

5. Fe2O3 + H2SO4 → ? - The balanced equation is: Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O - Reactants: Fe2O3, H2SO4 - Products: Fe2(SO4)3, H2O

6. CaO + HCl → ? - The balanced equation is: CaO + 2HCl → CaCl2 + H2O - Reactants: CaO, HCl - Products: CaCl2, H2O

7. Ag2O + HNO3 → ? - The balanced equation is: Ag2O + 2HNO3 → 2AgNO3 + H2O - Reactants: Ag2O, HNO3 - Products: 2AgNO3, H2O

8. Al2O3 + H2SO4 → ? - The balanced equation is: Al2O3 + 3H2SO4 → Al2(SO4)3 + 3H2O - Reactants: Al2O3, H2SO4 - Products: Al2(SO4)3, H2O

Please note that the coefficients in the balanced equations represent the stoichiometric ratios between the reactants and products.
