L10 - Stoichiometry

Flashcards generated from a lecture transcript focusing on key vocabulary and concepts related to quantifying reactions, stoichiometry, solutions, and concentration in chemistry.

Limiting Reagent

The reactant that runs out first in a chemical reaction, determining the maximum amount of product that can be formed.

Percentage Yield

A measure of how much of the reactants have been converted into products in a chemical reaction, often expressed as a percentage.

Stoichiometry

The ratio between the amounts of reactants and products in a balanced chemical equation.

Solutions

Homogeneous mixtures of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Solute

The substance that is dissolved in a solution.

Solvent

The substance that dissolves the solute in a solution.

Solution

A homogeneous mixture formed when a solute is dissolved in a solvent.

Concentration

The amount of solute dissolved in a unit volume of solution.

Balanced Equation

Ensuring that the number of atoms and the charges are equal on both sides of a chemical equation.

Molarity

The amount of solute (in moles) dissolved per liter of solution.

Aqueous (aq)

Indicates that the substance is dissolved in water within a chemical equation.

Moles

The relationship between the mass of a substance and the number of objects (atoms or molecules).
