Question

C-Co2-CaCo3-Co2-CaCo3-Ca(No3)2

Answer 1

Ответ:

C + O₂ = CO₂

CO₂ + CaO = CaCO₃

            t°

CaCO₃ →CO₂ + CaO

CO₂ + Ca(OH)₂ = CaCO₃ + H₂O

CaCO₃ +2HNO₃ = Ca(NO₃)₂ + H₂O + CO₂↑

Answer 2

The chemical formula you provided seems to be a combination of chemical elements and compounds. Let's break it down step by step:

1. C: This represents carbon, a non-metallic element.
2. Co2: This represents carbon dioxide, which is a gas composed of two oxygen atoms (O2) bonded to one carbon atom (C).
3. CaCO3: This represents calcium carbonate, a compound composed of one calcium atom (Ca) bonded to one carbon atom (C) and three oxygen atoms (O3).

Now, the structure you provided repeats twice, so let's separate it for clarity:

• Co2: Carbon dioxide
• CaCO3: Calcium carbonate
• Co2: Carbon dioxide
• CaCO3: Calcium carbonate

Finally, you mentioned "Ca(NO3)2," which represents calcium nitrate, a compound composed of one calcium atom (Ca) bonded to two nitrate groups, each containing one nitrogen atom (N) and three oxygen atoms (O3).

To summarize the entire chemical formula:

Carbon dioxide - Calcium carbonate - Carbon dioxide - Calcium carbonate - Calcium nitrate (Ca(NO3)2)
