What happens when a bath bomb is added to water?

• When a bath bomb is added to water, it dissolves and breaks down into particles.

How can we explain another phenomenon, like elephant toothpaste, where gas bubbles appear after combining different substances together?

• Combining different substances may result in forming something new, even inside a closed system.

• Combining different substances forces one of the substances to change to a gas.

• Combining different substances may result in particles rearranging and interacting in different ways.
