A chemical reaction, by definition, does not require air unless one of the constituents of the reaction is intended to be supplied by it.
Any reaction involved between atoms are chemical reactions.
Any chemical reaction need an activation energy to occur.
Any chemical reaction need an activation energy.
For example any chemical reaction need an activation energy.
Reacting to air is a chemical property because it involves a change in the chemical composition of the substance when it comes into contact with oxygen in the air, leading to the formation of new compounds. It reflects how a substance interacts with its environment on a molecular level.
Any chemical reaction.
A chemical substance formed as a result of a chemical reaction is called a product. Products can be either the desired end product of the reaction or byproducts that are formed during the reaction.
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
It is a chemical changes, as is any sort of reaction.
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.
Oxygen is an element, not a reaction of any form.
Any reaction occur.
