Chemical Formula Quizzes, Questions & Answers

Sitting through a chemistry class can be hard, especially when talking about chemical formulas – which represent elements and compounds as equations. For example, aluminum sulfate has the chemical formula of Al2(SO4)3. You’re probably familiar with H2O, which is two hydrogen molecules and one oxygen molecule, coming together to create water.

Here’s a test – what does the chemical formula of Al(OH)3 create? You know that aluminum is Al on the periodic table, oxygen is O, and hydrogen is H. Put this all together and you’ve got aluminum hydroxide! Chemical formulas can become very complicated, adding in bonds (=) and positive (+) and negative (-) charged molecules. To see how far you’ve come in learning chemical formulas, test your knowledge in one of our chemistry quizzes – they’re bound to create a reaction in your brain!
