Chemical Reaction and Stoichiometry Questions

10th - 11th

In this chemical reaction learning exercise, learners balance the given chemical reactions. Students decide which statements are true about chemical reactions. Learners also calculate the number of moles, grams, or molecules will be produced in a chemical reactions.

Answer Key

What is a Chemical Reaction?-Evidence of Change

In this chemical reactions worksheet, students experiment with hydrochloric acid and copper (I) chloride to identify the types of reactions they undergo with various other substances. They also observe the law of conservation of mass and record their observations of chemical reactions.

Chemical Reactions

In this writing chemical reactions worksheet, students solve 15 problems on their own paper using a 3 step-problem solving approach. In addition, students write six balanced equations and classify each reaction. They also write equations in aqueous solutions.

Did a Chemical Reaction "Really" Occur?

Pupils perform several different experiments to observe signs of chemical reactions and determine if reaction has occurred, use search engine to find Internet sites pertaining to chemical reactions, and write up brief summary of site.

Energy and Chemical Reactions

In this chemistry unit learning exercise, learners study the energy involved in chemical reactions. They solve 7 exercise sections on chemical equations.

Conservation During Chemical Reactions

In this chemical reaction activity, students are given the details of an experiment where sodium chloride and silver nitrate are mixed in a chemical reaction. Students answer nine questions about the chemical reaction, they determine the products made and write an equation for the reaction.

Chemical Reaction in a Baggy

Tenth graders observe various chemical reactions in the lab. In this chemistry lesson, 10th graders list the indications that a chemical reaction took place. They give real life examples of reactions they see everyday.


Sal introduces students of chemistry to "Stoichiometry," which is the calculation of measureable relationships of the reactants and products in a chemical reaction. Sal sets up a balanced chemical equation and then, using the Periodic Table of Elements, demonstrates how to use that table with the calculations involved in Stoichiometry in order to come up with the measureable values of each of the reactants.

Review of Stoichiometry

In this chemistry learning exercise, students answer 50 multiple choice questions on stoichiometric calculations, the mole and chemical reactions.

Types of Chemical Reactions

Chemistry hopefuls experience four different types of chemical reactions: single displacement, double displacement, synthesis, and decomposition. They will apply identification tests to the products as well. While this is absolutely a comprehensive chemistry lab, it is also designed to address the Common Core initiative for science literacy. You will appreciate the ease in teaching the instructional activity due to the well-thought-out plans provided.

How to Speed Up Chemical Reactions (and Get a Date)

How are chemical reactions like dating? A collision must first occur! In this hilarious approach to speeding up chemical reactions, viewers find out that five changes can increase the rate of reaction: smaller space, increased number of particles, increased temperature (and therefore velocity), increased surface area, and adding a catalyst. Teens will thoroughly enjoy and learn from this feature! Because of its quick pace, you will want to review each concept in more detail, but this is a worthy introduction.

I'm a Special Education teacher that collaborates with science most of the day. I've found lots of hands on and wonderful ideas for teaching science that I can use incorporating all of our students. There are so many that I was able to use all year long last year and still finding more this year. Love this site...
