Question

Describe the relationship of the atoms shown by:


A) The rearrangement of atoms is a chemical change.
B) Stability of the atoms in the molecule means a physical change.
C) A change in state of matter from a liquid to gas is a physical change.
D) A change in state of matter from solid to liquid is a physical change

Answer 1

The answer is A)The rearrangement of atoms is a chemical change.

Sorry that I was late to answer

Answer 2

Answer: A) The rearrangement of atoms is a chemical change.

Explanation:

A chemical change or reaction is the process in which one or more substances form new substances.

During chemical changes some chemical bonds (from the reactants) are broken and new chemical bonds (in the products) are formed.

Both the model with spheres and the chemical equation show that two initial substances, 1 molecule CH₄ (4 hydrogen atoms bonded to one carbon atom) and 2 molecules of oxygen (each formed by 2 atoms of oxygen) transform into two new different substances, 1 molecule of CO₂ (1 atom of carbon bonded to 2 atoms of oxygen) and 2 molecules of H₂O (2 atoms of hydrogen bonded to 1 atom of O).

As you see, the atoms were rearranged to form the new substances, which is a chemical change.
