To burn something requires oxidation (usually with O2 in the case of combustion).. therefore 'burning' is a chemical reaction with oxygen (O2)... Fuel + Oxygen (in air) --> carbon dioxide + water (The above works in most cases, obviously sulfur [for e.g.] would give SO2 and no water) H3CCH2CH3 (g) + 5 O2 (g)--> 3 CO2 (g) + 4 H2O(l) Propane + Oxygen --> Carbon Dioxide + Water In the case of fire works the oxidiser is (usually) Potassium Nitrate (the Nitrate ion [NO3-] containing oxygen reacts in place of O2). This makes equations more complex but in esence the principle is the same. I think equations as follows: For Carbon component--------- 4 KNO3(s) + 5 C(s) --> 5 CO2(g) + 2 K2O(s) + 2 N2(g) For Sulfur Component----------- 4 KNO3(s) + 5 S(s) --> 5 SO2(g) + 2 K2O(s) + 2 N2(g)
With physical reactions, like water, you can always get the substance back to its original form. If you melt ice you get water, but you can refreeze it to get ice again. Its properties are not changing. With burning wood, the properties are changing. You can change the ash back into wood.
Because when you mix the chemicals together a chemical reaction occurs and a new gas is produced.
Oxgyen, Carbon Dioxide, and Hydrogen were all produced in this experiment.
Burning is a chemical reaction because it is the result of multiple chemicals reacting with one another to change into something else. These changes are irreversible.
physical cas you cant reverse the effect of burning, where as you can reverse the effect of a chemical change
Because a new components are formed and the reaction is irreversible
because its fire
because it is
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Burning is a chemical reaction.
yes, because it is a chemical reaction (chemical reactions are irreversible).
Yes, the gunpowder reacts with oxygen. The oxygen comes from oxidizers perchlorates, chlorates, nitrates, permanganates, chromates or oxides.In propelling the rocket, potassium nitrate is used with black powder. Chlorates or perchlorates are used for the explosion as it reacts with carbon and sulfur rapidly. For the different colours of firework, various metal salts are used.
Methanol burning is a chemical reaction, a chemical change.
Definitely a chemical change, The elements in the firework undergo very rapid combustion (burning) which is a chemical change.
Yes.
Burning wood is a chemical reaction because combustion (burning) is an oxidation reaction.
Burning is an oxydation reaction.
Burning is a chemical reaction (oxidation).
Burning is a chemical reaction.
It is a chemical reaction because it changes and the change can't be revesed
yes, because it is a chemical reaction (chemical reactions are irreversible).
Yes, burning of fuel is always a chemical reaction.
Yes, the gunpowder reacts with oxygen.

Burning is a sign of a chemical change
Yes, burning anything is chemical.
