When gas is produced, you may observe bubbles forming in the liquid or substance, a change in volume or pressure, and possibly a release of gas with accompanying hissing or popping sounds. Depending on the type of gas and how it is being produced, there may also be changes in color or temperature.
An example of a new substance that forms as a gas during a chemical reaction is carbon dioxide (CO2). This gas is often produced when carbon-containing compounds, such as glucose, burn in the presence of oxygen.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Helium gas is a pure substance because it is made up of only one type of atom, specifically helium atoms.
A color change, formation of gas, formation of a precipitate, or change in temperature are signs of a chemical change.

Hydrogen gas is produced when any metal reacts with acids. This is a common reaction that is often used to test for the presence of metal in a substance.
Chemical. If vinegar reacts with baking soda, a new substance is produced. If something new is produced, it is chemical. In chemical reactions, things change what they are. Water splitting into hydrogen gas and oxygen is chemical, because hydrogen gas and oxygen gas is different from water.

Carbon monoxide is a colorless gas at 60°C. It is produced by the incomplete combustion of carbon-containing fuels.
An absorption spectrum is produced when a substance absorbs specific wavelengths of light as it passes through it. This absorption results in the dark lines or bands seen in the spectrum, which can be used to identify the elements present in the substance.
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.
Oxygen gas was the substance produced by the mint plant in Joseph Priestley's experiment. This discovery led to the understanding of plants releasing oxygen through the process of photosynthesis.

air is a substance because air is a gas and a gas is a substance.
Carbon dioxide, the same gas you breath out in respiration.
Yes, gas is a pure substance.
