Tetrahedral is a word which describes the shape of a molecule that has one atom in the center and is bound to four atoms by chemical bonds at the corners. It is then known as a tetrahedron.
This word, which is defined as a fictional group composed of a carbon atom double bonded to an oxygen atom, is spelled ________________.
In chemistry, a carbonyl group is a functional group (substituents within molecules) which is composed of a carbon atom which is double bonded to an oxygen atom (C=O). Compounds containing this group are called carbonyl compounds.
This word is a substance which is added in order to cause a chemical reaction. What is the correct spelling?
A reagent is a substance which is added to a system to cause a chemical reaction, or to test whether a reaction did or can occur. The word is often interchanged with reactant but is a separate entity.
This substance speeds up the rate of a chemical reaction. What is the correct spelling?
A catalyst is a substance which speeds up the rate of a chemical reaction but is not used up in the reaction; which means that it can be recovered after the reaction has occurred. Enzymes are examples of protein catalysts.
This process of making soap is spelled ______________________.
Saponification is the process by which fat or oil is converted into soap and alcohol by using heat in the presence of aqueous alkali. The fats used are animal fats or vegetable oil. In instances where they use sodium hydroxide, hard soap is produced.

When we were in school, there were certain subjects we had to take whether we wanted to or not (most often not). And when it comes to the sciences, we had to sit down in many biology, physics and chemistry classes. To many, chemistry may have seemed like a boring science, the only excitement being the occasional volcano baking soda reaction, getting to light the Bunsen burner and when a solution accidentally overflowed. Beyond that, the chemical reactions were a pain to remember for most, and trying to remember whether a hydrocarbon and oxygen mixture was combustible or corrosive just called on a migraine.
So, we won't make you relive those days of horror. Instead, we're going to test whether you remember how some of the words were spelled. Was it exothermic or exsothermic? Was the word supposed to be assitate or acetate? We've riddled this quiz with questions testing your knowledge on some of the most common words in the chemistry lexicon and it's up to you to choose the correct spelling for every word. Will you redeem yourself by acing this quiz, or is chemistry just not for you? Let's find out!
