Yes, because a gas is burned - an oxydation reaction.

This chemical reaction produces heat as well as carbon dioxide and water vapor as products from methane and oxygen gas. The heat also excites the electrons in the gases it produces, causing them to gain energy and rapidly emit this energy in the form of photons predominately with a wavelength of approximately 475 nm, which we perceive as blue light.

The reaction can be described by the following equation:

CH4 (g) + 2 O2 (g) => CO2 (g) + 2 H2O (g)

No, lighting a Bunsen burner is a physical reaction because it involves a change in state or appearance, but no new substances are formed. The reaction is reversible, as the burner can be turned off and back on without creating new chemicals.
