1. Negative view: Burn a candle in a closed jar and it extinguishes.
2. Positive view: Blow gently on a fire and see it flare up.
what is the substance formad when burning both hydrogen and ethanol in the air
Oxygen supports burning through the process of oxidation, in which oxygen molecules react with the atoms of the burning material, releasing energy in the form of heat and light. This can be proven by conducting controlled experiments in a controlled environment where oxygen is present, and observing how materials burn in its presence compared to in its absence.
Burning is combustion, which is an oxidation reaction that requires oxygen. Therefore oxygen promotes burning, as it is a reactant in the reaction, and higher concentrations of a reactant will result in a faster rate of reaction (collision theory).
Oxygen is the component of air that is used in the process of burning. It reacts with the fuel to produce heat and light.
When burning hydrogen in air, water vapor is formed as a byproduct. The chemical reaction can be represented as: 2H2 + O2 -> 2H2O.
When air blows, it provides a continuous supply of oxygen to the burning substance. Oxygen is necessary for combustion to occur, as it supports the chemical reactions that release heat and light. The increased airflow can enhance the combustion process, allowing the substance to burn more efficiently and at a higher intensity.
Cause dust can combust real fast and air supports burning the ground doesn't
cos it does not burn itself nor supports burning
Oxygen supports burning
Strange question. either you have lit some magnesium (in which case you have observed it burn) or not. The evidence is in the burning.
You may put some burning fuel (as a piece of coal or some gasoline, etc..) under an airtight pot connected to vacuum system to suck air. You notice on sucking the air the diminishing of the burning until got completely off. Even if you don't such the air, the burning will get less and less due to the consumption of the limited Oxygen inside the pot.
yes this is because it is the only gas that supports burning. yes
The sky is made of air and the air supports the air above it.

Oxygen.
Combustion consumes oxygen.
