Chemical Reactions CHM1020

These flashcards cover key concepts and terminology related to chemical reactions, including types of reactions, balancing equations, and associated vocabulary.

Chemical Reactions

Processes where substances transform into different substances by breaking and forming chemical bonds.

Reactants

Substances that undergo chemical changes in a reaction, found on the left side of a chemical equation.

Products

New substances formed as a result of a chemical reaction, found on the right side of a chemical equation.

Coefficients

Numbers placed before compounds in a chemical equation to indicate the number of molecules or atoms involved.

Balancing Equations

The process of ensuring that the same number of each type of atom appears on both sides of a chemical equation.

Combustion Reaction

A chemical reaction that typically involves a fuel and oxygen, producing carbon dioxide and water.

Dissociation

The process in which an ionic compound separates into its individual ions in an aqueous solution.

Spectator Ions

Ions in a solution that do not participate in a chemical reaction and remain unchanged.

Solubility Rules

Guidelines that predict whether an ionic compound will be soluble or insoluble in water.

Redox Reactions

Reactions that involve the transfer of electrons between species, leading to changes in oxidation states.

Combination Reaction

A type of reaction where two or more reactants combine to form a single product.

Decomposition Reaction

A reaction where a single compound breaks down into two or more elements or new compounds.

Single Replacement Reaction

A reaction where one element replaces another element in a compound.

Double Replacement Reaction

A reaction where two compounds exchange ions to form two new compounds.

Driving Forces

Factors that drive reactions, including the formation of gases, solids, or the transfer of electrons.

Aqueous Solution

A solution in which water is the solvent.

Oxidation

The process of losing electrons during a chemical reaction.

Reduction

The process of gaining electrons during a chemical reaction.

Activity Series

A list of metals arranged in order of decreasing reactivity.
