Question

hoàn thiện sơ đồ phản ứng :
O2-CO2-CO-CO2-CACO3-CaCL2

Answer 1

O2+ C----->CO2

CO2+C----->2CO

2CO +O2----->2CO2

CO2+ CaO------>CaCO3

CaCO3+ 2HCl------>CaCl2 +H2O +CO2

Chúc bạn học tốt

Answer 2

O\(_2\) + C =\(^{t^0}\)=> CO\(_2\)

CO\(_2\) + C =t\(^0\)=> 2CO

2CO + O\(_2\) =t\(^0\)=> 2CO\(_2\)

CO\(_2\) + CaO => CaCO\(_3\)

CaCO\(_3\) + 2HCl => H\(_2\)O + CO\(_2\) + CaCl\(_2\)

Answer 3

O2+C--->CO2

CO2+C--->2CO

2CO+O2--->2CO2

CO2+CaO--->CaCO3

CaCO3+2HCl--->H2O+CO2+CaCl2
