when rain falls, when there is a bush-fire, i know you may think "what a bush-fire?" but sometimes government or people do bush-fires on purpose to make fertilization (some plants have to be burnt to fertilize
Chemical Energy
An element is a substance that cannot be broken down into simpler substances by chemical reactions. Each element is made up of only one type of atom. Examples of elements include oxygen, gold, and carbon.
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
in chemical reactions, energy is absorbed or released when chemical bonds are broken and new ones are formed.
atom
the result that comes by mixing the chemical to chemical
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
yes
An element is a substance that chemical reactions cannot break down into simpler substances. Elements are made up of only one type of atom and cannot be further broken down by chemical means. Examples of elements include gold, oxygen, and carbon.
Alkalis
Enzymes speed up chemical reactions inside living organisms. They are made up of proteins.
Chemical Energy
Energy is made available through chemical reactions by breaking and forming chemical bonds in molecules. During this process, the energy stored in the bonds is either released or absorbed, leading to a change in the energy content of the molecules involved. Usable energy released in chemical reactions is often converted into different forms, such as heat or mechanical energy, to power various biological processes or physical activities.
Chemical reactions are:- synthesis- decomposition- single displacement- double displacementThe classification is made taking into account the reactants and products.
Examples: sulfate, nitrate, chloride, fluoride, iodide, nitride, carbide of aluminium, etc.

Detrital- made of sediment grains Orgains- Made of fossils Chemical- from due to chemical reactions I hope this helped you enough :)
