Question

C → CO → CO2 → K2CO3→ KCl → KNO3→ O2

Answer 1

Ответ:

2co+o2=2co2

co2+2kon=k2co3+h2o

k2co3+2hcl=2kcl+co2+h2o

kcl+agno3=kno3+agcl

2kno3=2kno2+o2

Answer 2

Ответ:

2C+O2=2CO;CO+O2=CO2;Co2+2KOH=K2CO3+H2O;K2CO3+CaCl2=CaCO3 +2KCl;KCl+AgNO3=KNO3+AgCl;2KNO3=2KNO2+O2

Answer 3

The sequence you've listed appears to represent a series of chemical reactions involving different elements and compounds. Here's a breakdown of these reactions:

1. C (Carbon): Carbon is the initial element in the sequence.

2. CO (Carbon Monoxide): Carbon reacts with oxygen to form carbon monoxide.

3. CO2 (Carbon Dioxide): Carbon monoxide reacts with additional oxygen to form carbon dioxide.

4. K2CO3 (Potassium Carbonate): Carbon dioxide is involved in a reaction with potassium compounds to form potassium carbonate (K2CO3).

5. KCl (Potassium Chloride): Potassium carbonate can react with hydrochloric acid (HCl) to form potassium chloride (KCl) and release carbon dioxide as a byproduct.

6. KNO3 (Potassium Nitrate): Potassium chloride can undergo a reaction with nitric acid (HNO3) to form potassium nitrate (KNO3).

7. O2 (Oxygen): The reactions you've listed seem to be part of a complex sequence, and oxygen may be involved in some of these reactions as well.

It's important to note that chemical reactions can be complex and may require specific conditions, reactants, and catalysts to occur. The sequence you've provided is a simplified representation and does not include all the details of these reactions. If you have specific questions about any of these reactions or need more information about a particular step, please feel free to ask.
