A chemical reaction occurs when the conditions for a chemical reaction exist.
Which is a really lame answer, so let's play with it. You want to make some water and carbon dioxide. You have some hexane, which is C6H14. If you set the hexane on fire, it will react with the oxygen in the air to produce carbon dioxide and water.

∙ 9y agoWhen atoms and molecules come together and split, chemical reactions occur. Atoms gain stability through these chemical reactions. They are rapid reactions that occur at given temperatures and at a chemical concentration.

∙ 13y agoChemical bonding occurs when two atoms with unfull valence orbitals react and exchange or share electrons; the result is either a covalent bond (shared electrons so that each has a full shell) or an ionic bond (the electron is completely removed from one atom and given to the other; the differently charged ions then attract and bond).

∙ 6y agoChemical changes occur when a substance combines with another substance to form a new substance. These are called chemical reactions and they are irreversible or very hard to reverse. When a chemical reaction takes place, the atoms are rearranged and the reaction is accompanied by an energy change when the new products are formed.
A chemical change occurs when two substances react and cause a substance to change.making it a chemical change
It will occur when November 6... Joke i don't know too because I'am a researcher too I do this because I'am making science assignment... And that date that is my birth day...
A chemical change occurs when the bonds between atoms are broken and reformed so that the resulting change produces a new substance
new stuf forms

What would you expect to happen if you mixed argon and sodium together?
Since argon is a noble gas, I wouldn't expect much to happen; specifically, I wouldn't expect any chemical reaction.
What is the difference between an exothermic and endothermic reaction?
Exothermic (hyperthermic) reaction: a chemical reaction that releases energy,*Endothermic (hypothermic) reaction: a chemical reaction that absorbs energy.** Energy = heat, light, etc.The direction of Heat transfer:Exothermic reactions transfer heat energy to the environment.Endothermic reactions transfer heat energy from the environment .
Explain how wood burning in a fire place undergoes a chemical change?
Burning is an oxydation reaction so a chemical change.
A substance which helps a reaction to take place but that does not take an active part is a?
A substance which helps with chemical reactions, by making them possible at all, or reducing the effort required, is a catalyst.
What speeds up reactions?
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
What take place during a chemical reaction?
During a chemical reaction the breaking of the older bonds and formation of the new bonds take place.
What type of reaction take place in rancidity?
chemical reaction takes place in rancidity
What reaction will take place with baking soda and vinegar?
a chemical reaction..
What is meant by thermodynamics of a chemical reaction?
It refers to the energy changes that take place during a chemical reaction.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
Is neutralising an acid a chemical reaction?
Yes. A reaction does take place in neutralisation.
Can a chemical reaction reaction take place in which energy is neither absorbed or released?
no
What shows changes that take place during a chemical reaction?
A chemical equation
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
If energy is the form of heat is requried for a chemical reaction to take place the reaction is?
Endothermic
Where on the enzyme molecule does the chemical reaction take place?
in the middle
Where do chemical reaction take place in cells?
every were in the cell
