Yes, combustion is a chemical reaction, because it is a reaction between a molecule and oxygen (O2) to produce a new molecule plus CO2 (if it's a complete combustion) or CO (if it is an incomplete combustion). Combustion is also an exothermic reaction, which means that heat is released.
Decomposition reactions differ from combustion reactions because a combustion
reaction is an exothermic reaction in which the substance combines with oxygen, and a decomposition reaction is when a substance is broken down into simpler substances.The short answer is combustion reactions are a subset of synthesis reactions that require one of the reactants to be oxygen. Common combustion of organic molecules results in the formation of CO2 . However, it is not required that combustion be limited to organic molecules. They are different from decomposition reactions in the same way synthesis is the opposite of decomposition.
A decomposition reaction turns molecules into smaller molecules (or even atoms). Examples of decomposition reactions are electrolyses, photolysis, thermolysis (and many more).
Whereas a combustion reaction combines molecules (such as methane) with oxygen to form other molecules (in this case, CO2 and H2O)
So to sum it up.
Decomposition
AB --> A + B
Combustion
AB + O2 --> AO + BO
Combustion contains explosive force where chemical reactions are not always such.
Explosions are just very fast violent chemical reactions. Nuclear fission causes an explosion; oxidation of methane can be considered almost an explosion.
Yes, it is. The molecule itself changes here. Complete combustion results in the formation of carbon dioxide from the starting fuel (i.e. organic matter).
Because combustion is an oxidation reaction.
A combustion reaction is only a reaction with oxygen (oxidation).
A composition reaction is more general, it is a reaction involving reactants to obtain products.
An increase in mass is normally caused by chemical reactions with other materials, Similarly, a loss in mass can be explained by a physical change of state or by the removal of elements or compounds by chemical reactions.
Mass is never lost nor gained - neither in chemical reactions, nor in other cases.
Usually, only electrons participate in chemical reations. The other subatomic particles play a larger role in nuclear chemistry.
potential energy is created by separating charges with chemical reactions so that one terminal is negatively charged, while the other terminal becomes positively charged.
Blast wave, as with any other explosive bomb.
Special chemical reactions such as hydrogen bonding.
Not ALL reactions are chemicals. When chemicals reacte with other chemicals it is called as chemical reactions.
Chemical reactions are different molecules reacting with each other to form one or more products. Chemical reactions are done in everyday life from your breathing to digesting food to combusting gasoline to drive.
A single chemical that breaks down into other substances during chemical reactions is "decomposing".
Chemical compounds are formed by the combining of elements or other compounds through chemical reactions. They are defined as pure chemical substances.
Some chemical reactions in the body do move back and forth. Other chemical reactions can only be pressed one way because when they are pushed in the other direction nothing happens.
true they decrease the rates of chemical reactions this i right not the other dudes awnser:P
Thermodynamics do not actually refer to chemical reactions but rather the effect chemical reactions and other interactions have on particle's.
Chemical reactions and powder
By chemical reactions they form other compounds.
Electrophilic reagents are chemical species which in the course of chemical reactions, acquire electrons or a share in electrons from other molecules or ions. Nucleophilic reagents do the opposite of electrophilic reagents.
