Question

Напишите пожалуйста молекулярные и ионные уравнения реакций,протекающих при сливании раствора:а)азотной кислоты и гидроксида кальция:б)соляной кислоты и карбоната калия.Пожалуйста очень надо,если не решу училка завалит

Answer 1

2HNO3+Ca(OH)2----Ca(NO3)2+2H2O
2H(+1)+2NO3(-1)+Ca(OH)2------Ca(+2)+2NO3(-1)+2H2O
2H(+1)+Ca(OH)2---Ca(+2)+2H2O

2HCl+K2CO3----2KCl+H2O+CO2
2H(+1)+2K(+1)+2CO3(-2)-----2K(+1)+2Cl(-1)+H2O+CO2
2H(+1)+2CO3(-2)-----2Cl(-1)+H2O+CO2

Answer 2

Molekular equation for the reaction between nitric acid and calcium hydroxide:

The molecular equation for the reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2) can be written as follows:

HNO3 + Ca(OH)2 → Ca(NO3)2 + H2O

Ionic equation for the reaction between nitric acid and calcium hydroxide:

To write the ionic equation, we need to break down the reactants and products into their respective ions. Nitric acid dissociates into H+ and NO3- ions, while calcium hydroxide dissociates into Ca2+ and OH- ions. The ionic equation for the reaction is as follows:

H+ + NO3- + Ca2+ + 2OH- → Ca2+ + 2NO3- + 2H2O

Molekular equation for the reaction between hydrochloric acid and potassium carbonate:

The molecular equation for the reaction between hydrochloric acid (HCl) and potassium carbonate (K2CO3) can be written as follows:

2HCl + K2CO3 → 2KCl + H2O + CO2

Ionic equation for the reaction between hydrochloric acid and potassium carbonate:

To write the ionic equation, we need to break down the reactants and products into their respective ions. Hydrochloric acid dissociates into H+ and Cl- ions, while potassium carbonate dissociates into 2K+ and CO3^2- ions. The ionic equation for the reaction is as follows:

2H+ + 2Cl- + 2K+ + CO3^2- → 2K+ + 2Cl- + H2O + CO2

Please note that these equations represent the overall reaction and do not account for the stoichiometry or the state of the reactants and products.
