In this chemistry review worksheet, students practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.
Curated OER
Energy Changes in Reactions
In this chemical bonds worksheet, students determine how much energy is needed to break bonds. Students classify reactions as exothermic or endothermic and identify a reaction as reversible. This worksheet has 4 problems to solve.
Curated OER
Electron Dot Structures/Lewis Structures
In this elements worksheet, students practice drawing electron dot structures for atoms. Students draw the Lewis Structures for molecules with single and multiple bonds plus polyatomic ions. This worksheet has 33 problems to solve.
Curated OER
Alkanes: Thermal Cracking
In this alkanes instructional activity, students compare the average standard bond enthalpy for common bonds. Then students complete 3 short answer questions.
Curated OER
