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

A) The rearrangement of atoms is a chemical change.

Step-by-step explanation:

A chemical change is a process in which new substance (product) is formed due to a chemical reaction. Chemical reaction give rise to a chemical change can occur by simply applying heat to a substance.

In the chemical reaction symbolized, a molecule of methane reacts with two molecules of oxygen to produce carbon (IV) oxide and two molecules of water.

i.e
`CH_(4)` +2
`O_(2)` ⇒
`CO_(2)` + 2
`H_(2)O`

Thus, the relationship of the atoms shown is the rearrangement of the atoms of reactants to give new products due to a chemical reaction.

Answer 2

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

Ch4 +2O2 ⇒ CO2 +2H2O

(Methane + Oxygen → Carbon dioxide + Water)

Methane gas reacts with Oxygen, and it causes combustion, producing carbon dioxide and water vapor to Atmosphere.
