Which one is a chemical change-eletrolysis of water or sodium chloride exposed in sunlight?
The electrolysis of water is a chemical change because it breaks down water molecules into hydrogen and oxygen gas. On the other hand, sodium chloride exposed to sunlight is a physical change as it may undergo phase changes, but the chemical composition remains the same.
Why is it a chemical change when the leaves turn different colors in the fall?
As plants receive less sunlight, they change color. They are green because they have a lot of sunlight and are able to produce glucose and other energy chemicals. The less sunlight they receive, the less chemicals they produce.
Is chemicals in a battery reacting to the power of a flashlight a physical or chemical change?

Is a banana changing colors a chemical or physical change?
The change in color of a banana from green to yellow is a chemical change. This is because it involves a chemical reaction as the banana ripens, causing the chlorophyll to break down and other pigments to become more prominent.
Why is a glowstick a chemical change?
A glowstick undergoes a chemical change when the chemicals inside mix, leading to a reaction that produces light. This change cannot be reversed, as the reaction permanently alters the composition of the chemicals inside the glowstick to create the glowing effect.

What is the difference between a chemical change and a physical change in a reaction?
A physical change occur when the molecular structure of chemicals are not changed.A chemical change occur when the molecular structure of chemicals is changed.
Why does Aquamarine fade?
Aquamarine can fade due to prolonged exposure to intense light, such as sunlight, which can cause the color to become paler or change slightly. Additionally, exposure to chemicals and heat can also contribute to the fading of aquamarine.
