What are the primary pollutants that come from burning coal

ANSWER: The primary pollutants that come from coal burning are CARBON MONOXIDE, NITROGEN OXIDE, SULFUR DIOXIDE, PARTICULATE MATTER AND MERCURY.

EXPLANATION: Primary pollutants refer to those pollutants that are released directly into the environment from their sources. Secondary pollutants are those that are formed as a result of further chemical reactions in the atmosphere. The burning of coal releases some primary pollutants into the environment, these include: carbon monoxide, nitrogen oxide, sulfur dioxide, particulate matter and mercury. These pollutants are toxic to plants and animal lives.  

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
