air, methane, carbon dioxide, sulfur containing gases
Inert gases
These are gases or particles evolved during chemical reactions.
It is a chemical change as it releases gases into the air.
noble gases are already stable.
noble gases
The burning of natural gases is a chemical change. It involves a chemical reaction between the natural gases (such as methane) and oxygen in the air to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. This process is not reversible, and it results in the formation of new substances with different properties than the original gases.
Because before about 1950, the noble gases were not known to form any chemical compounds.
it is a chemical change because it produces gases
Chemical reactions
not always, but sometimes
- A mixture of gases- A chemical reaction producing a compound
Gas IS not a kind of energy, but different gases can CONTAIN energy. Certain gases contain chemical energy (they can be burned). There is also energy related to the pressure on the gas.Gas IS not a kind of energy, but different gases can CONTAIN energy. Certain gases contain chemical energy (they can be burned).
