Using sunlight,
6 CO2 + 12 H2O ===> C6H12O6 + 6 H2O + 6 O2

The most important chemical reaction of alkanes is probably combustion, where they react with oxygen to produce carbon dioxide and water, releasing heat energy. This reaction is important because it is used for energy production in engines, heating systems, and other applications.
Gasoline burning is an oxidation reaction, a reaction with oxygen.So, burning is a chemical change. And fire was the most important discovery of human beings.
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
This is a chemical reaction.
It depends: just try to relate, try to write a chemical equation for and see if there are byproducts. Most likely, if the same chemical still has its same properties After the reaction, a chemical reaction has not occurred.

The most important: to have the reactants !
The most important sign is when you smell an odor . when you began to smell and odor that is a automatic chemical change.

Nuclear reactions involve the reaction of nuclei and does not involve transfer of electron as in regular chemical reactions.
An important factor in all chemical reactions is the type and arrangement of atoms involved. The way in which atoms interact with one another dictates the outcome of a chemical reaction.
The most important concept in solving stoichiometry problems is understanding how to use mole ratios from a balanced chemical equation to convert between different substances involved in the reaction. This allows you to determine the amounts of reactants consumed or products formed in a chemical reaction.
do not break bonds
