how are new chemicals formed

Best answer

A chemical reaction happens when substances break apart or combine to form one or more new substances. New substances form whenbonds break and new bonds form. The chemical properties of the new substances are different from those of the original substances. Some chemical reactions produce a precipitate. Click to see full answer

People also ask

New substance are formed by a chemical change? Yes all chemical changes involve the formation of new substances because the elemental molecules combine to form a substance with different chemical and physical properties than the original combinants. For example: Oxygen (flamable gas) plus Hydrogen (flamable gas) = water non flamable liquid

When two hydrogen atoms combine with one oxygen atom, it becomes the compound water. One may also ask, what is an example of a new substance being formed? A chemical change (chemical reaction) is a change of materials into other, new materials with different properties, and one or new substances are formed.

How do atoms combine to make new substances? When atoms combine to form a new substance, they are forming chemical bonds that bind them together. It is these bonds that define what is formed.

A chemical reaction forms new products. But it’s important to realize that the products are just rearrangements of the same atoms. If we take the reactants, and rearrange the atoms a bit, we get the products. The products you get out of a chemical reaction are completely new substances, and they can have completely new properties.
