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.
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.
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.
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.
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.
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.
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.
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 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.
An amphoteric compound is one that is able to react both as an acid and a base, depending on the medium, according to the Bronsted-Lowry theory. It comes from the Greek word “amphoteros,” which means “each or both of two.”
It is the study of electromagnetic forces. What the correct spelling of the word?
Electromagnetism is the study of electromagnetic forces, which is the physical interaction that occurs between particles which are electrically charged. They typically exhibit electromagnetic fields and are one of the fundamental interactions in nature.
How do you spell the word which describes the process by which a molecule acquires a positive or negative charge?
Ionization, sometimes spelled ionization, is the process by which a molecule or atom acquires a positive or negative charge by either gaining or losing electrons in order to form ions. One example, gas ionization, occurs within fluorescent lamps.
It is the study of the interaction between matter and electromagnetic radiation. How is it spelled?
Spectroscopy is the study of the interaction between electromagnetic radiation and matter. It splits the light into constituent wavelengths in a similar fashion to that of a prism with the different energy levels being quantified.
How do you describe the word which measures the resistance to flow?
The viscosity of a fluid is the measure of its resistance to flow. Some people use thickness as a synonym to viscose, and one example includes honey or blood and water. The first two options are more viscose or thicker than water.
Centrifugal forces separate particles in this reaction. How is this word spelled?
Centrifugation is a laboratory technique which involves using a centrifugal force to separate particles in solution according to its shape, size, viscosity and density. It is mostly used to separate two miscible substances.
