Помогите пожалуйста, даю 15 баллов C→CO²→Na²CO³→CO²→CaCO³
1. C+O₂=CO₂ 2. CO₂+2Na₂O=Na₂CO₃ 3. Na₂CO₃+2CH3COOH = 2CH3COONa+H₂O+CO₂ 4. CO₂+CaO=CaCO₃
1. C+O₂=CO₂
2. CO₂+2NaOH=Na₂CO₃+H₂O
3. Na₂CO₃+2HCl=2NaCL+H₂O+CO₂
4. CO₂+Ca(OH)₂=CaCO₃+H₂O
C+O₂=CO₂ CO₂+2NaOH=Na₂CO₃+H₂O Na₂CO₃+2HCl=2NaCL+H₂O+CO₂ CO₂+Ca(OH)₂=CaCO₃+H₂O
