Question

C + CO2 + H2CO3 + CO2 + CaCO3 + CaO

Answer 1

Ответ:

C+O2=CO2

CO2+H2O=H2CO3

H2CO3+CaO=CaCO3+H2O

CaCO3=CaO+CO2

Answer 2

The equation you've provided appears to represent a chemical reaction involving carbon (C), carbon dioxide (CO2), carbonic acid (H2CO3), calcium carbonate (CaCO3), and calcium oxide (CaO). However, it seems incomplete and lacks proper coefficients and directionality. To properly balance the equation, I'll provide a balanced chemical equation for a typical reaction involving these substances:

2CaCO3(s) → 2CaO(s) + 2CO2(g) + O2(g)

This equation represents the thermal decomposition of calcium carbonate (CaCO3) to produce calcium oxide (CaO), carbon dioxide (CO2), and oxygen gas (O2). The balanced coefficients ensure that the number of atoms of each element is the same on both sides of the equation, thus conserving mass and charge.
