Question

Совершите такие преобразования
1) MgCO3-CO2-CaCO3-Ca(HCO3)2-CaCO3-Co2
2) C-CO2-MgCO3-Mg(HCO3)2-CO2

Answer 1

Первая цепочка.

$textbf{1)} MgCO_{3} xrightarrow{text{hspace{2mm}thspace{2mm}}} MgO + CO_{2} uparrow$

$textbf{2)} CO_{2} + CaO longrightarrow CaCO_{3} downarrow$

$textbf{3)} CaCO_{3} + CO_{2} + H_{2}O longrightarrow Ca(HCO_{3})_{2}$

$textbf{4)} Ca(HCO_{3})_{2} xrightarrow{text{hspace{2mm}thspace{2mm}}} CaCO_{3} downarrow + CO_{2} uparrow + H_{2}O$

$textbf{5)} CaCO_{3} xrightarrow{text{hspace{2mm}thspace{2mm}}} CaO + CO_{2} uparrow$

Вторая цепочка.

$textbf{1)} C + O_{2} xrightarrow{text{hspace{2mm}thspace{2mm}}} CO_{2} uparrow$

$textbf{2)} CO_{2} + MgO longrightarrow MgCO_{3} downarrow$

$textbf{3)} MgCO_{3} + CO_{2} + H_{2}O longrightarrow Mg(HCO_{3})_{2}$

$textbf{4)} Mg(HCO_{3})_{2} xrightarrow{text{hspace{2mm}thspace{2mm}}} MgCO_{3} downarrow + CO_{2} uparrow + H_{2}O$
