Viết PT HH thực hiện chuỗi phản ứng : CO2 -> CaCO3 -> CaCl2 -> NaCl CuO -> CuCl2 -> Cu(OH)2 -> CuSO4 K2O -> KOH -> K2CO3 -> K2SO4

Để viết phương trình hóa học cho chuỗi phản ứng đã cho, chúng ta sẽ thực hiện từng bước một. 1. **CO2 -> CaCO3**: \[ \text{CaO} + \text{CO}_2 \rightarrow \text{CaCO}_3 \] 2. **CaCO3 -> CaCl2**: \[ \text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2 \] 3. **CaCl2 -> NaCl**: \[ \text{CaCl}_2 + 2\text{NaOH} \rightarrow 2\text{NaCl} + \text{Ca(OH)}_2 \] 4. **CuO -> CuCl2**: \[ \text{CuO} + 2\text{HCl} \rightarrow \text{CuCl}_2 + \text{H}_2\text{O} \] 5. **CuCl2 -> Cu(OH)2**: \[ \text{CuCl}_2 + 2\text{NaOH} \rightarrow \text{Cu(OH)}_2 + 2\text{NaCl} \] 6. **Cu(OH)2 -> CuSO4**: \[ \text{Cu(OH)}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + 2\text{H}_2\text{O} \] 7. **K2O -> KOH**: \[ \text{K}_2\text{O} + \text{H}_2\text{O} \rightarrow 2\text{KOH} \] 8. **KOH -> K2CO3**: \[ 2\text{KOH} + \text{CO}_2 \rightarrow \text{K}_2\text{CO}_3 + \text{H}_2\text{O} \] 9. **K2CO3 -> K2SO4**: \[ \text{K}_2\text{CO}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{K}_2\text{SO}_4 + \text{H}_2\text{O} + \text{CO}_2 \] Tóm lại, các phương trình hóa học cho chuỗi phản ứng trên là: 1. \(\text{CaO} + \text{CO}_2 \rightarrow \text{CaCO}_3\) 2. \(\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2\) 3. \(\text{CaCl}_2 + 2\text{NaOH} \rightarrow 2\text{NaCl} + \text{Ca(OH)}_2\) 4. \(\text{CuO} + 2\text{HCl} \rightarrow \text{CuCl}_2 + \text{H}_2\text{O}\) 5. \(\text{CuCl}_2 + 2\text{NaOH} \rightarrow \text{Cu(OH)}_2 + 2\text{NaCl}\) 6. \(\text{Cu(OH)}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{CuSO}_4 + 2\text{H}_2\text{O}\) 7. \(\text{K}_2\text{O} + \text{H}_2\text{O} \rightarrow 2\text{KOH}\) 8. \(2\text{KOH} + \text{CO}_2 \rightarrow \text{K}_2\text{CO}_3 + \text{H}_2\text{O}\) 9. \(\text{K}_2\text{CO}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{K}_2\text{SO}_4 + \text{H}_2\text{O} + \text{CO}_2\) Hy vọng rằng điều này sẽ giúp ích cho bạn trong việc hiểu rõ hơn về chuỗi phản ứng hóa học này!
