Answer

The production of nitric acid typically requires:

  • High temperature (around 800°C)
  • High pressure (around 5-10 atm)
  • A catalyst such as platinum or rhodium
  • The use of ammonia and oxygen as raw materials.

Step 3

Answer

Yes, producing magnesium oxide as a continuous process has several benefits:

  • Improved Efficiency: Continuous processes allow for a more efficient production flow, resulting in better allocation of resources.
  • Reduced Downtime: These processes minimize the downtime associated with reloading materials, leading to higher productivity.
  • Consistent Quality: Continuous production can improve the consistency of the product quality due to controlled conditions throughout the process.
