Question

K⇒K2O⇒KOH⇒K2CO3⇒H2CO3⇒CO2

Answer 1

2K+O2=K2O
3K2O+3H2O=6KOH
2KOH+H2CO3=K2CO3+2H2O
K2CO3+2HCl=H2CO3+2KCl
H2CO3=CO2+H2O

Answer 2

The sequence you've provided appears to be a chemical reaction pathway involving potassium (K) and its compounds. Here's a breakdown of each step in the reaction:

1. K (potassium) reacts to form K2O (potassium oxide).
2. K2O reacts with water (H2O) to form KOH (potassium hydroxide).
3. KOH can further react with carbon dioxide (CO2) to form K2CO3 (potassium carbonate).
4. K2CO3 can then react with acids, like HCl (hydrochloric acid), to form H2CO3 (carbonic acid).
5. H2CO3 can decompose to release CO2 (carbon dioxide) and water (H2O) as follows: H2CO3 → H2O + CO2

This sequence represents a series of chemical reactions involving potassium and its compounds, leading to the formation of carbon dioxide (CO2) as a product. It's important to note that chemical reactions often involve various conditions, catalysts, and specific reactant concentrations, which can influence the reaction pathways and outcomes. Additionally, the overall reaction may involve more detailed reaction mechanisms and intermediates not explicitly mentioned in the sequence.
