Answer:
Decomposition reaction
Explanation:
2NO —> O2 + N2
The above equation clearly indicates decomposition because a single reactant (NO) produces two products (O2 and N2). Decomposition reaction is a reaction in which a single compound breaks down into two or more elements or compound as seen in the equation above.
Answer:
BY increasing pressure and decreasing temperature.
Explanation:
- The solubility of a gas increases with decrease in the temperature.
- Also the solubility of a gas increases with increasing pressure.
- A gas can be compressed by increasing the pressure and decreasing the temperature.
- FOR example the gas in domestic LPG cylinders are in compressed form inside the cylinder.
- A gas takes the form of a liquid after compressing. Whenever it comes back to normal temperature and pressure it takes back to its gaseous form back.
The gaseous oxygen is water soluble and does not react with it
O2 + 2H2O + 4 e= 4 OH-
