About This Quiz
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!
How do you correctly spell this type of electrode?
A cathode is a type of electrode in which electrical current exits the polarized electrical circuit. Positively charges cations always move toward the cathode, and the opposite applies for the anode.
This word describes a grouping of metallic elements. How is it spelled?
Lanthanides are a grouping of metallic elements which range from 57 to 71, from the elements lanthanum to lutetium. They can also be called lanthanoids.
This word is a type of metal which belongs to Group 1 of the periodic table. Which of these ways do you spell it?
The word alkali is usually seen before the word metal, and they are defined as any metallic element which belongs to Group 1 of the periodic table. Some examples include sodium, potassium and lithium.
It is defined as the combining capacity of elements in a chemical compound. How is it spelled?
Valency is defined as the combining capacity of an element or the measure of its combining powers when it forms a chemical compound or molecule.
Which of these words is the correct spelling of the calculation of reactants and products in a chemical reaction?
Stoichiometry is the precise calculation of the reactants and the products in chemical reactions. It is founded on the law of conservation of mass, which states that the total mass of reactants equals the total mass of the initial products.
How is this technique which uses electrical current spelled?
Electrolysis is a technique which used electrical current to drive a non-spontaneous chemical reaction, thereby producing changes in the substance.
It is another word for a large molecule of repeating subunits. How is it correctly spelled?
A polymer is a large molecule which is made up of repeating subunits called monomers. They usually have high boiling and melting points and sometimes a high molecular mass.
It is a chemical compound which donates an electron pair. How do you spell this word?
A nucleophile is a chemical compound or species which donates an electron pair to an electrophile in order to form a chemical bond in a reaction. Molecules which have at least one pair of free electrons can act as nucleophiles.
This chemical compound has a net charge of zero. How do you spell it?
A zwitterion is a chemical compound which has a net charge of zero, which makes it electrically neutral. It does, however, have both positive and negative charges in it.
Which of these is the correct spelling of the word which has many carbon to carbon double bonds?
An unsaturated compound is one which has a carbon to carbon double and/or triple bonds. Because of this bonding, it does not contain the highest amount of hydrogen atoms like the saturated compounds.
What is the correct spelling of this periodic table element?
Beryllium is a chemical element which is represented by the symbol Be and the atomic number 4. The alkaline earth metal is relatively rare and can be found as a product of large atomic nuclei colliding with cosmic rays.
This reaction happens after opening a champagne bottle.
Effervescence is the escape of gases from an aqueous solution causing it to foam or fizz upon its release. An example of this is opening a carbonated beverage such as champagne.
What is the correct spelling of this word?
Halogens are a group of non-metallic elements found in Group 17 of the periodic table. There are five of them (fluorine, chlorine, bromine, iodine, and astatine). They are known to form strong acidic compounds with hydrogen.
One of these is a process by which a substance absorbs moisture. What is the correct spelling?
Deliquescence is the process by which a substance absorbs moisture from the atmosphere until it completely dissolves in the water, thereby forming a solution.
Ductility is a synonym for this word. What is its correct spelling?
Malleability, also called ductility, is the measure of a material’s ability to undergo deformation before it breaks or ruptures. It is typically expressed as percent elongation.
It is able to exist in two or more forms. What is the correct spelling?
An allotrope is an element which can exist in two or more forms. The differentiation can be in the way that they are bonded or the way that they are arranged.
What is the correct spelling of the element which has the chemical element with the atomic number 54?
Xenon is a chemical element which is represented by the symbol Xe and the atomic number 54. It is a colorless and odorless noble gas, and it can be found in products like flash lamps and general anesthesia.
How do you correctly spell this type of lab tool?
A pipette is a laboratory tool which is used to transport, or store measured volumes of liquid. They come in several sizes and designs made from different materials including glass.
How is this chemical element spelled?
Palladium is a chemical element which is represented by the symbol Pd and the atomic number 46. The silvery white metal was discovered by William Hyde Wollaston and is used in dentistry, hydrogen purification and jewelry.
How do you spell the word which describes one atom bonded to four atoms?
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.
