After a chemical reaction new compouds (called also products) are formed.
This could refer to a chemical transformation (chemical change), a chemical reaction, or spontaneous change. Some changes require another substance or substances to be mixed together. Some reactions will occur by themselves without any outside manipulation or stimulation.
A molecule is two or more atoms held together by covalent chemical bonds. A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a unique and defined chemical structure; they consist of a fixed ratio of atoms that are held together in a defined spatial arrangement by chemical bonds. Chemical compounds can be molecular compounds held together by covalent bonds, salts held together by ionic bonds, intermetallic compounds held together by metallic bonds, or complexes held together by coordinate covalent bonds
No and element cannot be broken down or changed into another substance through a chemical change. The number of protons in the nucleus of an atom determines the identity of the substance. But, a chemical change involves only the atoms electrons. -SmartyPants94

A chemical change.
Yes, many chemical reactions produce a new solid substance from two solid reactants. These reactions are slow, and the solids must be ground up very fine and pressed together tightly for a reaction to occur at any significant rate (see Related Questions about what affect the rate of a chemical reaction).
Chemical reactions
In a chemical reaction, no atoms are lost. It is basically a mixture of two substances.Below is an example. (Though I'm just using random letters -- the symbols don't actually make a substance)AJK + JD = AJ2KDIn a chemical change, a completely new substance with new properties is created.Here is another example. (Though, again, I'm just using random letters -- the symbols don't actually make up a substance)AJK + JD = AJKD
All chemical reactions are red-ox reactions. In other words if one component is getting oxidized the other component have to be reduced. All chemical reactions have reactants and products.If you would like to have more information, please do not hesitate to ask.A chemical reaction is when energy is released or absorbed. Also an example of a chemical reaction is a base and an acid. When an acid hits a base it makes salt and water. Reversible reactions are ones where the reaction can be paralleled to have the substance come back to its original state. A chemical reaction is also irreversible, because you can't get the original substance back. E.g: If you bake a cake with milk, flour and sugar and you mix it all together after you have baked it you can't get each substance back therefore it is irreversible and is a Chemical Reaction
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
