Periodic Table, Chemical Reaction, and Acid & Base Flashcard

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, where elements with similar properties are grouped together.

Front

What is a chemical reaction?

Back

A process that involves the transformation of one set of chemical substances into another, involving the breaking and forming of bonds.

Front

What is the pH scale?

Back

A scale used to measure the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What is an acid?

Back

A substance that donates protons (H+) in a solution and has a pH less than 7.

Front

What is a base?

Back

A substance that accepts protons (H+) or donates hydroxide ions (OH-) in a solution and has a pH greater than 7.

Front

What is a combination reaction?

Back

A type of chemical reaction where two or more substances combine to form a single product, represented by the general formula A + B -> AB.

Front

What is a decomposition reaction?

Back

A type of chemical reaction where a single compound breaks down into two or more simpler substances, represented by the general formula AB -> A + B.

Front

What is a single replacement reaction?

Back

A type of chemical reaction where one element replaces another in a compound, represented by the general formula A + BC -> AC + B.

Front

What is a double replacement reaction?

Back

A type of chemical reaction where the anions and cations of two different compounds exchange places, represented by the general formula AB + CD -> AD + CB.

Front

What are metals?

Back

Elements that are typically shiny, malleable, ductile, and good conductors of heat and electricity.
