During the combustion of any organic material, there are two primary products. The first is water vapor and the second is carbon dioxide gas.
The gas produced by the burning of fuel is carbon dioxide.
Paper gas
When burning sulfur, sulfur dioxide gas is produced. This gas has a strong odor similar to burnt matches and can be harmful to human health and the environment.
Neon is an element, classified as a noble gas, and it has nothing to do with burning wood. Neon does not burn, nor is it produced by burning.
carbon dickoxide
Carbon dioxide (CO2) is a gas produced by burning fossil fuels that contains the element carbon. It is a greenhouse gas that contributes to climate change.

sulfur
During coal burning, carbon dioxide is produced as a byproduct. This is a type of greenhouse gas that contributes to climate change.
Carbon monoxide is produced when burning fuels without sufficient air supply. Carbon monoxide is toxic and can be dangerous if inhaled in high concentrations.
The gas produced is hydrogen gas (H2). The reaction between sodium metal and water is a highly exothermic reaction that liberates hydrogen gas, which in turn reacts explosively with oxygen in the air when ignited by a burning splint.
You can test for the gas produced by collecting it in a test tube and then performing tests like the "pop" test using a burning splint. The gas produced when sodium reacts with water is hydrogen gas, which will ignite with a "pop" sound when exposed to a flame.
