Is a match being lit a physical or chemical change?
A burning match is a chemical change. Burning anything is a chemical change because it forms a new substance. A physical change just alters the shape or appearance of a substance. For example, burning wood turns it into ash, a new substance, so its a chemical change. Cutting a piece of wood in half changes how it looks, but its still the same substance as before, just separated into two pieces. There are three common types of evidence of a chemical change. 1. A change in color due to a reaction with another substance. The match is reacting with fire and oxygen. 2. The production of a gas. the match gives off a smoke. 3. Formation of a precipitate or a solid that forms and saparates from a liquid mixture. burning a match does not form a precipitate, but adding acid to milk causes the proteins in the milk to undergo a chemical change that alters their structure, so they clump together. * A burning match is an example of a chemical reaction in progress. When the matchstick burns, oxygen from the air is used, mainly to form water vapor and carbon dioxide. The smoke that is generated, is a complex mixture of gases and small particles from the matchstick.
What gas is produced by fires?
Mostly carbon dioxide. If the supply of oxygen is restricted, carbon monoxide as well. Other things depend on what is in the burning substance, sulfur will give sulfur dioxide for example, and there may be nitrogen oxides.
What are the chemistry and physics of fire?
A fire requires three things, Fuel, Heat, and Oxygen.The fuel supplies the energy of combustion, and provides more heat (is exothermic) to keep the fire going.The oxygen is combined with the fuel and this is the exothermic reaction.The initial heat is supplied by some external source, such as a match, an electrical short circuit, a chemical reaction.
Is mostly likely a chemical change salt dissolving in water or a match burning?
A match burning is a chemical change. Salt dissolving in water is a physical change.
Can burning match burn petrol fuel?
Yes, of course.
If you put a match in pure oxygen will the oxygen burn?
No, the match wil burn... oxigen is a non combustible gas, is supports burning and does not burn by itself
What happens when you drop a match in a water bottle then put the top on the water bottle?
If the match is lit and the bottle is empty, the match will burn all the oxygen and then it will go out, since it requires oxygen to keep burning. If the bottle is full, you will have a wet match.
Why match burning a fast reaction?
the friction of the match causes the chemicals inside the match head to ignite...in cause as long as there is oxygen in the room the match will light as quick as you strike the match....in other words...the match only lights as fast as you can strike it
Does combustion occur when lighting a match in the air?
Yes, combustion is simply the chemical reaction of a substance with oxygen molecules. In this case the match and match head are reacting with the ocygen int he air.

Why does burning a match involve chemical reactions?
A chemical reaction suggests that something is altered(typically non-reversible)down to the chemical elements. A physical change is changing the appearance of an object(is usually reversible) A match burning changes the match down to a irreversible level
How does a burning match actually burn?
The match burns because of the friction between the sandpaper and the match. Try rubbing your hands together, it does the same thing! Can you feel your hands warm up? That is the same thing that is happening with the match. But no oxygen, and the fire goes out!
What reaction occurred when burning a match stick?
The gas will explode in presence of oxygen! (and your match blown out, and hopefully you're not!)D.T.T.A.H.Only if brought in contact with H2 gas WITHOUT ANY O2 it would distiguish through absence of oxygen, but in practice this is IMPOSSIBLE to do (oxygen being present all the time as long as your match is burning, how else would it burn? see?)
Why can't pure oxygen ignite?
Oxygen is neither combustible nor flammable. It supports the combustion of a combustible substance. For example, if you light a match and expose it to pure oxygen, the flame will grow larger and brighter while it's in the oxygen, but the oxygen itself will not ignite.
What type of energy is in the match before it is burned and while it is burning?
While the match is burning it has thermal energy
What gas is produced by fires?
Mostly carbon dioxide. If the supply of oxygen is restricted, carbon monoxide as well. Other things depend on what is in the burning substance, sulfur will give sulfur dioxide for example, and there may be nitrogen oxides.
