Curated OER
Stoichiometry (gases and masses)
In this chemistry worksheet, students identify how many liters of oxygen can be consumed to form carbon dioxide. Then they identify how many liters of sulfur dioxide are produced if the gas is at STP.

Mole Ratios and Reaction Stoichiometry
Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth instructional activity in an 11-part series has scholars use stoichiometry to find the theoretical yield of a...

Molar Volume of a Gas
What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions.

Everything You Ever Wanted To Know About Hot Wire Chemical Vapor Deposition, But Were Afraid To Ask
To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...
Curated OER
Quantitative Problems (Mass)
For this chemistry worksheet, students identify how much aluminum and hydrochloric acid is needed to produced a certain amount of hydrogen gas. Then they identify how many grams of oxygen are used.
Curated OER
stoichiometric (molarity, gases, mass)
In this chemistry worksheet, students identify the volume that is required for complete precipitation. Then they identify what concentration of the base is in moles per liter. Students also name the formula weight of a hydroxide.
Curated OER
Ideal Gas Law
High schoolers explain and use ideal gas law and use the law to solve problems. They use conversion factors to convert mass to mol. Also students use stoichiometry skills previously learned.
