At least one change in chemical bonding.
Any, that is their function.
Any chemical reaction, only some solubility.
Any chemical reaction.
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron
This is an irreversible change as any cooked food cannot be returned to an uncooked state. This makes it a chemical reaction/change. Hope this helps, Kind regards, sasjade
The atoms are unchanged in any chemical reaction. Only the outer electron shell is affected as chemical bonds are formed.
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.
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.
Any reaction occur.
Oxygen is an element, not a reaction of any form.
For a chemical change to occur, there must be a chemical reaction. A chemical reaction would be either endothermic (uses energy, mostly heat), or exothermic (produces energy, again mostly heat). Any change in temperature of the reactants, as measured by a thermometer, will tell you not only ifa chemical reaction occurred, but also which kind of chemical reaction. No temperature change usually indicates that no reaction has occurred, a decrease in temperature would indicate an endothermic reaction, while an increase in temperature would indicate an exothermic reaction.
