Stoichiometry and Dimensional Analysis

A set of 35 flashcards focusing on key vocabulary and concepts related to stoichiometry, dimensional analysis, and exam preparation strategies.

Stoichiometry

The calculation of reactants and products in chemical reactions.

Mole Ratio

A ratio used in stoichiometry to relate the amounts of reactants and products.

Dimensional Analysis

A mathematical technique used to convert between units using conversion factors.

Molar Mass

The mass of one mole of a substance, typically expressed in grams per mole.

Molecule

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Reactant

A substance that takes part in and undergoes change during a chemical reaction.

Product

A substance that is produced as a result of a chemical reaction.

Law of Conservation of Matter

A principle stating that matter cannot be created or destroyed in a closed system.

Coefficient

A number placed in front of a chemical formula in a balanced equation to indicate the number of moles.

Balanced Equation

An equation that has the same number of atoms of each element on both sides of the reaction.

Conversion Factor

A ratio used to convert from one unit to another.

6.02 x 10^23

Avogadro's number, representing the number of atoms or molecules in one mole.

Mass A

Refers to the mass of reactant A before a chemical reaction.

Mass B

Refers to the mass of product B after a chemical reaction.

Moles A

The amount of substance A measured in moles before a reaction.

Moles B

The amount of product B measured in moles after a reaction.

Reactant Mass

The total mass of all reactants before a reaction occurs.

Product Mass

The total mass of all products after a reaction occurs.

Significant Figures

Digits in a number that carry meaningful information about its precision.

Practice Sheet

A worksheet used to practice stoichiometry problems and dimensional analysis.

Short Answer Practice

Practice questions that require concise responses based on learned material.

Exam Preparation

The process of studying and reviewing material to prepare for an upcoming exam.

Statement 1

Relating molecules in a chemical reaction (e.g., CH4 + 2O2 → CO2 + 2H2O).

Statement 2

Relating moles in a chemical reaction using coefficients (e.g., 1 mol CH4 + 2 mol O2).

Statement 3

Relating amounts of particles in a chemical reaction using Avogadro's number.

Statement 4

Relating masses in grams for reactants and products to verify conservation of matter.

Chemical Reaction

A process that leads to the transformation of one set of chemical substances to another.

Stoichiometric Calculations

Glucose

A simple sugar which is an important energy source in living organisms, with the formula C6H12O6.

Photosynthesis

The process by which green plants use sunlight to synthesize foods from carbon dioxide and water.

Grams to Moles Conversion

The process of converting grams of a substance to moles based on molar mass.

Conversion Process

The series of steps taken to convert measurements from one unit to another.

Example Problem

A demonstration of how to apply stoichiometry principles to solve a specific question.
