Question

Написать молекулярные и ионные уравнения при помощи которых можно осуществить уравнения следующих реакций na2o->naoh->na2co3->mgco3->co2->baco3

Answer 1

Na2o+h2o-2naoh
2naoh+co2-na2co3+h2o
2na+2oh- + co2-2na+ + co32- +h2o
2oh-+co2-co32-+h2o
na2co3+mgcl2-mgco3+2nacl
2na+ +co32-+ mg2+ + 2cl- -mgco3+ 2na+ + 2 cl-
mg2+ + co32- - mgco3
mgco3-mgo+co2
co2+bao-baco3

Answer 2

Molecular and Ionic Equations for the Given Reactions

To write the molecular and ionic equations for the given reactions, let's break down each reaction step by step:

1. Na2O -> NaOH - Molecular Equation: Na2O + H2O -> 2NaOH - Ionic Equation: 2Na+ + O2- + 2H2O -> 2Na+ + 2OH- - Net Ionic Equation: O2- + 2H2O -> 2OH-

2. NaOH -> Na2CO3 - Molecular Equation: 2NaOH + CO2 -> Na2CO3 + H2O - Ionic Equation: 2Na+ + 2OH- + CO2 -> Na2CO3 + H2O - Net Ionic Equation: CO2 + 2OH- -> Na2CO3 + H2O

3. Na2CO3 -> MgCO3 - Molecular Equation: Na2CO3 + MgCl2 -> MgCO3 + 2NaCl - Ionic Equation: 2Na+ + CO3^2- + Mg^2+ + 2Cl- -> MgCO3 + 2Na+ + 2Cl- - Net Ionic Equation: CO3^2- + Mg^2+ -> MgCO3

4. MgCO3 -> CO2 - Molecular Equation: MgCO3 -> MgO + CO2 - Ionic Equation: MgCO3 -> MgO + CO2 - Net Ionic Equation: None (no ions involved)

5. CO2 -> BaCO3 - Molecular Equation: CO2 + Ba(OH)2 -> BaCO3 + H2O - Ionic Equation: CO2 + 2OH- + Ba^2+ -> BaCO3 + H2O - Net Ionic Equation: CO2 + 2OH- -> BaCO3 + H2O

6. BaCO3 - Molecular Equation: BaCO3 -> BaO + CO2 - Ionic Equation: BaCO3 -> BaO + CO2 - Net Ionic Equation: None (no ions involved)

Please note that the net ionic equations only include the species that are directly involved in the reaction and exclude spectator ions.
