combustion
Hydrogen (H2) is an example of a substance that yields only water and heat when it burns. When hydrogen burns in the presence of oxygen, it combines to form water (H2O) as the only byproduct, making it a clean and efficient fuel source.
oxygen
When a substance burns, it undergoes a chemical reaction with oxygen called combustion. During this process, the substance reacts with oxygen to produce heat and light energy, along with new chemical compounds like carbon dioxide and water vapor.
In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
oxygen
The substance that burns in oxygen to provide us with energy is glucose. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the primary energy source for our cells.
When something burns in the presence of oxygen, it undergoes a chemical reaction called combustion. During combustion, the substance reacts with oxygen to produce heat, light, and new chemical compounds like carbon dioxide and water vapor. This process is exothermic, meaning it releases energy in the form of heat and light.

This is the burning of a substance in the presence of oxygen.

When a substance burns in oxygen, it is called combustion. It is a chemical reaction that produces heat and light, usually accompanied by the release of carbon dioxide and water vapor.
Most thing burn in the presence of oxygen.
Identification of oxygen can be done through various tests such as the glowing splint test, where a glowing splint relights in the presence of oxygen. Oxygen gas also supports combustion, so a substance that burns more brightly or vigorously in its presence likely indicates the presence of oxygen. Additionally, oxygen gas turns a colorless solution of manganese(IV) oxide pale pink, serving as another identification test.
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.
