Give me some H2O! According to Khan Academy, "Chemistry is the study of matter, and all matter is made up of atoms." And you'll find atoms in everything. In the world of chemistry, it's hard to find something that doesn't have a chemical formula, from just one letter to a whole jumble of them.
In your chemistry class, you probably spent a lot of time learning about chemical formulas. From the 118 elements that are known to mankind, many of them can be added together and in different varieties. While the difference between carbon monoxide and carbon dioxide is just one oxygen atom in the equation, the difference in real life is deadly - though thankfully for us, not all chemical formulas are that dangerous!
From something as simple as water to nail polish remover, can you give us the names of these chemical formulas? Adding two hydrogen atoms and one oxygen atoms is one chemical formula that everyone needs to survive! Your food might be a little bland, but you could solve it with the combination of sodium (Na) and chlorine (Cl). If you want to take off your nail polish, you might need some C3H6O.
When you think about the things you use daily, there's a chemical for almost anything. From caffeine to aspirin to baking soda, let's find out if you're passing chemistry!
