What else can I help you with?
Are new molecules formed when a chemical change occurs?
ye s there are
Is formation of water from its element physical change?
No, the formation of water from its elements (hydrogen and oxygen) is a chemical change because new substances with different properties are formed. In this case, a chemical reaction occurs between hydrogen and oxygen molecules to produce water molecules.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
How do the substances change after a chemical reaction?
During a chemical reaction, bonds are broken between the atoms of the reactants and new bonds form to make the products. Essentially, the atoms of the reactants are rearranged to form the products.
What type of reaction occurs between dye and cellulose?
A dye can bond with cellulose fibers through a chemical process called absorption dyeing. This involves forming strong chemical bonds between the dye molecules and the cellulose, resulting in the coloration of the material.
What kind of chemical bond occurs between different water molecules?
hydrogen bound
What are the similarities between biological weathering and chemical weathering?
Weathering is weathering, no matter how it occurs. Both chemical and biological weathering wear down rock. They simply go about it in different ways.

What reaction occurs when a molecule is formed from the bonding of atoms ions or simpler molecules?
Chemical bonding occurs when atoms, ions, or molecules combine to form a new molecule. This process involves the sharing or transfer of electrons between the bonding entities to achieve a stable configuration, resulting in the formation of a new compound with unique chemical properties.

What is the relation between absorption altraviolent light?
Absorption of ultraviolet light occurs when molecules absorb the energy of UV photons, leading to electronic transitions within the molecule. This absorption can cause changes in molecular structure or generate reactive species that can lead to biological effects like DNA damage or sunburn. Different molecules absorb UV light differently based on their chemical structure.
How does biological evolution differ from chemical evolution?
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
