How will oxygen appear in the final chemical equation?
- O2(g) as a product
- O2(g) as a reactant
- O(g) as a product
- 2O(g) as a reactant​

In order for a high temperature boiler or steam engine to produce superheated water, or steam: the heat source must be greater than 100°c the water must be permitted to evaporate quickly the system must be sealed and become pressurized above atmospheric pressure the vapor pressure must be kept below 760 mm(hg)
