Only eight problems are on this competitive national chemistry exam. It required the balancing of chemical equations, solving stoichiometry questions, and more. This is part two of three of the national exam. Also available is a...

Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

Here is a general chemistry worksheet that incorporates practical applications. Four questions employ critical thinking about solutions, boiling and freezing points, and molar mass. Your class will practice what they learn in class by...

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...

If you need a homework assignment for your chemistry class, add this one to the possibilities. This assignment is composed of six questions including the identification of oxidizing and reducing agents, recognizing different redox...

In this energy and matter worksheet, students define 28 terms related to moles, matter, energy, the Law of Conservation of Energy, mass, properties of matter and states of matter.

Here is a straightforward practice test for first year chemistry learners. Responders balance equations, identify types of reactions, represent electron configurations, and solve stoichiometry problems. Keep this handy to use as...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

Prepare your chemistry charges for stoichiometry with this PowerPoint. The objective is to be able to calculate molar mass for different compounds. Beginning with the foundational definition of moles and moving through atomic and...

Young scholars are introduced to the mole concept using a discovery-based method. Lesson includes activities with candy that allow students to discover the rules for mole-item, item-mole, mole-mass, and mass-mole conversions.

Students recognize the concepts of the five general types of chemical reaction: combination, decomposition, single replacement, double replacement and combustion. They practice classifying chemical equations and determine the moles in a...

In this making standard solutions worksheet, learners read about the process of making a standard solution and perform 3 background calculations necessary to make standard solutions. Students then make a solution by weighing a given...

Students find moles and molecules used when a candle burns. In this moles and molecules lesson plan, students calculate the initial mass of a candle and the mass of a candle after it burns for 3 minutes. They calculate the mass lost when...

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

For this Hess' Law worksheet, students write their data and calculations from the lab they performed on Hess's Law. They calculate the heat of reactions per mole of substances used and calculate the theoretical heat of reaction and...

In this gas worksheet, learners use the ideal gas law to find volumes of gases, pressure of gases, moles of gases, mass of gases and molecules of gases. They find unknowns at standard temperature and pressure and they calculate the...

In this solutions worksheet, students solve twelve problems including calculating products made in reactions, determining limiting reagents, calculating molarity of solutions, determining percent composition, and finding volumes and...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

In this dimensional analysis worksheet, students solve four problems using dimensional analysis to solve for moles and masses of products.

In this gas worksheet, students apply the gas laws by calculating the mass, volume, pressure, or temperature for given gas reactions. This worksheet has 13 word problems.

In this chemistry learning exercise, students write the balanced equation for the formation of one mole of fat from its elements under standard conditions. Then they write the balanced equation of the combustion of this fat. Students use...

In this chemistry worksheet, students calculate to find the molar mass of water. Then they identify how many moles of hydrogen atoms and oxygen atoms they would have in a beaker. Students also write the chemical formula of cholesterol.
