What burns a substance in the presence of oxygen?
combustion
What substance will the carbon in methane change into when it burns in oxygen?
In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
Do substances actually burn in combustion?
Combustion is the process of rapid oxidation of a substance i.e. its rapid reaction with oxygen. This whole process is called burning. So, it can be said that the substance burns in combustion.
Why is oxygen used up when a fire burns?
a) oxygen does not burn b) oxygen combines with the fuel - it is NOT a catalyst. c) a fire does acellerate when oxygen is added.
Why the melting point of a substance is a physical property but flammability is a chemical property?
When a substance melts, it changes state from solid to liquid. This does not alter the substance's chemical composition, so melting point is a physical property. Flammability means burning, and when a substance burns, it reacts with oxygen to produce a new substance that was not there before. This is therefore a chemical property.
What burns a substance in the presence of oxygen?
combustion
What colorless gas burns with oxygen?
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.
When a substance is combined with oxygen the substance is?
Often it's an oxide. For example, carbon burns in air to form its oxides, carbon monoxide and carbon dioxide. However, there are other possibilities. Hydrogen burns in oxygen to produce water.
When paper burns in a fire what is a reactant?
When paper burns in a fire, the reactants are mostly carbon (the main substance in the paper) and oxygen(from the air).
When a substance burns it reacts with a gas called?
Oxygen is the gas most commonly associated with burning.
Why is sulfur burning a chemical change?
When sulfur burns it reacts with oxygen to form sulfur dioxide, which is an entirely different substance from sulfur or oxygen.
What substances burn faster in oxygen?
Any substance that burns in air is likely to burn faster in pure oxygen, if all other conditions are equal.
Is oxygen a burning gas?
Oxygen, when mixed with a combustible substance, or gas and enough heat, will cause combustion, and is a gas. So it is indeed, a gas that burns.
What substance will the carbon in methane change into when it burns in oxygen?
In carbondioxide: CH4 + 3 O2 ==> CO2 + 2 H2O
What substance burns in oxygen to give us energy?
Many. for example coal, wood, natural gas, gasoline, ...
If Hydrogen is combustible substance and oxygen is also combustible substance but the product water is non combustible substance Why?
When hydrogen burns, it is combining with oxygen. Once it has combined to form water, the molecule does not want to readily accept more oxygen atoms. Fire is rapid oxidation, so if it is already oxidized, it is done.
Do substances actually burn in combustion?
Combustion is the process of rapid oxidation of a substance i.e. its rapid reaction with oxygen. This whole process is called burning. So, it can be said that the substance burns in combustion.
