1)C→Co2→Ba(Hco3)2→Co2→Na2Co3→MgCo3→Mg(Hco3)2→Co2
2) BaCo3→Co2→KHCo3→K2Co3→KHCo3
3)Mh3→(NH4)2Co3→NH3→NH4HCo3→Co2→C

Ответ:

Объяснение:

1)C→CO₂→Ba(HCO₃)₂→CO₂→Na₂CO₃→MgCO₃→Mg(HCO₃)₂→CO₂

C+O₂=CO₂

CO₂+Ba(OH)₂+H₂O=Ba(HCO₃)₂

Ba(HCO₃)₂+HCI= BaCI₂+CO₂↑+H₂O

CO₂+Na₂O=Na₂CO₃

Na₂CO₃+Mg(NO₃)₂=MgCO₃↓+NaNO₃

MgCO₃+H₂O+CO₂=Mg(HCO₃)₂

Mg(HCO₃)₂+t⁰ = MgCO₃ + H₂O + CO₂↑

2) BaCO₃→CO₂→KHCO₃→K₂CO₃→KHCO₃

BaCO₃+t°C= BaO+CO₂↑

CO₂(избыток)+KOH=KHCO₃

2KHCO₃+t°C=K₂CO₃+CO₂↑+H₂O

K₂CO₃+ СО₂ + Н₂О = 2KHCO₃

3) MgH₃→NH₃→(NH₄)CO₃→NH₃→NH₄HCO₃→CO₂→C

MgH₃+6H₂O=3Mg(OH)₂+2NH₃↑

2NH₃ + CO₂ + H₂O = (NH₄)₂CO₃

(NH₄)₂CO₃ = CO₂↑ + 2NH₃↑ + H₂O

NH₃+CO₂+H₂O=NH₄HCO₃

NH₄HCO₃= NH₃+CO₂↑+H₂O

CO₂+H₂=C+H₂O
