Balancing Chemical Reactions and Energy Concepts

A series of flashcards designed to help students understand key vocabulary and concepts related to balancing chemical reactions and energy interactions.

Nitrogen Dioxide (NO2)

A chemical compound formed from nitrogen and oxygen, typically produced during combustion.

Balanced Equation

An equation where the number of atoms for each element is equal on both sides of the reaction.

Limiting Reagent

The reactant that is completely consumed first in a chemical reaction, limiting the amount of product formed.

Moles

A unit of measurement in chemistry that represents a specific quantity of particles, atoms, or molecules.

Stoichiometry

The part of chemistry that involves using relationships between reactants and products in a chemical reaction to calculate quantities.

Exothermic Reaction

A chemical reaction that releases heat, resulting in an increase in the temperature of the surroundings.

Endothermic Reaction

A chemical reaction that absorbs heat from the surroundings, causing a decrease in the temperature of the surroundings.

Conservation of Mass

A principle stating that mass cannot be created or destroyed in a chemical reaction.

Conservation of Energy

A principle stating that energy cannot be created or destroyed, only transformed from one form to another.

Coefficient

A number placed in front of a chemical formula in a balanced equation to indicate the ratio of the substances involved.

Grams to Moles Conversion

The process of calculating the number of moles of a substance based on its mass and molar mass.

Thermal Energy

The total potential and kinetic energy of the particles in a substance, which is related to its temperature.
