Acids and Bases
This property of an acid or base tells how strong it is, and is measured on a logarithmic scale (usually from 0 to 14).
What is pH?
Newton's first law of motion is often known as the principle of this concept.
What is inertia?
The molecules on the left-hand side of a chemical equation are known as these.
What are reactants?
This chemist is known for her extensive work on radiation; she also coined the term "radioactivity".
Who is Curie?
This well-known acid-base indicator usually comes in thin strips, turning red when placed in an acid and blue when placed in a base.
What is litmus paper?
This law states that energy can neither be created nor destroyed.
What is the law of conservation of energy?
This is the name for a substance that decreases the activation energy for a reaction, but does not actually get changed during the reaction.
What is a catalyst?
This Austrian physicist made many significant contributions to the field of quantum mechanics; he is famous for a thought experiment involving a cat in a box.
Who is Schroedinger?
This term refers to a molecule that can donate a hydrogen ion (a proton) to another substance.
What is an acid?
This set of three (or four) laws describes the role of energy in closed systems.
What are the laws of thermodynamics?
When the number of atoms of each element on both sides of a chemical equation are equivalent, the equation is said to be ____.
What is "balanced"?
This scientist is known for his contributions to the study of electricity, including the popularization of terms like "cathode" and "anode". The SI unit of charge is also named after him.
Who is Faraday?
Combining an acid and a base neutralizes both to form water and a member of this group of substances.
What are salts?
The branch of physics that concerns the motion of objects is known as this.
What is kinematics?
This type of reaction occurs when two different molecules combine to make a single product.
What is synthesis?
This scientist won the Nobel Prize in physics for discovering the existence of quanta; a famous constant in quantum physics is named after him.
Who is Planck?
The process of slowly adding a known substance to an unknown substance in order to find the composition of the latter is known as this.
What is titration?
This number measures the elasticity or stiffness of a given solid, and is generally measured in kilopascals.
What is Young's modulus?
This type of reaction, of the form
A + BC → B + AC
involves the switching of the first reactant with part of the second reactant to form two new molecules.
What is a single replacement reaction?
This physicist earned the Nobel Prize in physics for his experiment that allowed him to produce X-rays, which were originally named after him.
Who is Röntgen?
