Question

Решите пожалуйста ионные уравнения (по три строчки) 1) K3PO4+AgNO3 2) HNO3+Ca(OH)2 3) K2CO3+H2SO4

Answer 1

K3PO4 + 3AgNO3 = 3KNO3 + Ag3PO4↓
3K(+) + PO4(3-) + 3Ag(+) + 3NO3(-) = 3K(+) + 3NO3(-) + Ag3PO4↓
PO4(3-) + Ag(+) =  + Ag3PO4↓

Ca(OH)2 + 2HNO3 = Ca(NO3)2 + 2H2O
Ca(OH)2 + 2H(+) + 2NO3(-) = Ca(2+) + 2NO3(-) + 2H2O
Ca(OH)2 + 2H(+) = Ca(2+) + 2H2O

K2CO3 + H2SO4 = K2SO4 + H2O + CO2↑
2K(+) + Co3(2-)+2H(+) + SO4(2-)= 2K(+)+SO4(2-)+H2O+CO2↑
2H(+) + CO3(2-) = H2O + CO2↑

Answer 2

Ion Equations:

1) K3PO4 + AgNO3: - The reaction between potassium phosphate (K3PO4) and silver nitrate (AgNO3) can be represented by the following ion equation: ``` 3K+ + PO4^3- + 3Ag+ + 3NO3- → Ag3PO4 + 3K+ + 3NO3- ``` - This equation shows the exchange of ions between the two compounds, resulting in the formation of silver phosphate (Ag3PO4) and the remaining ions.

2) HNO3 + Ca(OH)2: - The reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2) can be represented by the following ion equation: ``` H+ + NO3- + Ca2+ + 2OH- → Ca(NO3)2 + 2H2O ``` - This equation shows the exchange of ions between the two compounds, resulting in the formation of calcium nitrate (Ca(NO3)2) and water (H2O).

3) K2CO3 + H2SO4: - The reaction between potassium carbonate (K2CO3) and sulfuric acid (H2SO4) can be represented by the following ion equation: ``` 2K+ + CO3^2- + 2H+ + SO4^2- → K2SO4 + H2O + CO2 ``` - This equation shows the exchange of ions between the two compounds, resulting in the formation of potassium sulfate (K2SO4), water (H2O), and carbon dioxide (CO2).

Please note that the above equations represent the ion exchange reactions between the compounds. The actual chemical reactions may involve additional steps or occur in different forms depending on the conditions and concentrations of the reactants.
