In this stoichiometry worksheet, students use four balanced equations to calculate mole of products made, moles of reactants needed for chemical reactions to proceed and mass of reactants needed to produce products.

For this chemical equations worksheet, students review the steps to balancing equations and then complete a graphic organizer by balancing 10 chemical reactions.

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test.

Focus on oxidation-reduction reactions with a review worksheet. Junior chemists answer short-answer questions before they write balanced half-reaction and full-reaction equations.

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

An overview of acid and base compounds and their reactions is presented with this handout. Pupils name compounds and write chemical formulas. They write net ionic equations and explain how acidic solutions might conduct electricity. This...

In this balancing equations worksheet, students determine the type of reaction and write the balanced equation. Students read the word description and write the symbol of each element using the periodic table.

Five practice stoichiometry problems plus their answers fill this chemistry worksheet. Because the answers are spread across the bottom of the page, this would best be used as your class is just learning how to perform mole and mass...

Students investigate energy balance equation for five fictitious middle school students by using an energy balance clinic scenario.

Did you know when you mix the reactants sulfur, tungsten, and silver, you get the products SWAg? The simulation begins with making sandwiches, to show pupils reactants and products of something familiar. They then can make water,...

For this chemical equations worksheet, students are given the trends for the reactions between the alkaline earth metals with water, the solubility of the Group II hydroxides and the solubility of the Group II sulphates.

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...
