Mommy Hippo: Yes hun.
Baby Hippo: What are some element compounds insided of him?
Mommy Hippo: Well their is carbon dioxide and sodium chloride, but there are many more.
Baby Hippo: Wait! What are elements then.
Mommy: Elements are pure substances that can not be broken down into simpler substances.
Baby: Oh, okay. Mommy I have a test for you. Remember that red stuff that pours out of our food and then mixes with the water to look different? What is that
Mommy: Haha that is a mixture or combination of two or more substances that aren't chemically bonded. Now I have a test for you. What is a compound?
Baby: I'm pretty sure it's a pure substance composed of two or more elemetns that are chemically combined.
Mommy: Good job, I love you.



Solution:
A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent.
The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of molecular size.
