Name two other gaseous products formed when coal is burned

Answer 1

When coal is burned, two other gaseous products formed in addition to sulfur dioxide (SO₂) are:

1. Carbon dioxide (CO₂)
2. Water vapor (H₂O)

These gases are byproducts of the combustion process, where the carbon and hydrogen in the coal react with oxygen.
