PURPOSE: To compare the experimental mass to the theoretical mass of a product of a chemical reaction. Given the mole relationships in a balanced chemical equation, and the mass of one of the reactants, it is possible to determine the number of moles of every other substance taking part in the reaction.

LAB PURPOSE: 1) To practice the techniques used to determine mass and volume 2) To learn to calculate the density of a variety of objects.

Purpose: The student will determine the heat of crystallization of a wax sample.

Set up an organized chemistry review with stations covering topics such as chemical and physical changes, components of chemical equations (vocabulary review), modeling formulas, recognizing balanced and unbalanced equations, modeling chemical equations, fill-in-the-blanks atomic structure vocabulary, atomic structure table (with element name, symbol, atomic mass, atomic number, protons, neutrons, electrons), building an atom model, and chemical reactions review task card questions.

PURPOSE: To calculate the specific heat of a metal using mass and temperature data obtained by using a calorimeter.

6 Types of Chemical Reactions

By observing reactions between single elements and compounds, scientists have been able to determine a list of elements in order of their activity. In this experiment, you will observe many different chemical reactions, and you will construct your own list of elements in order of their activity.

This is a test on atomic structure. It is appropriate for a high school physical science or chemistry class. Types of questions include multiple choice, fill in the blank, and computation. Topics covered: atoms, atomic structure, mass and charge of subatomic particles, ions, isotopes, Rutherford, Dalton, Bohr, numbers of protons, neutrons, and electrons in an atom, and calculating the average atomic mass.

This test consist of 58 questions that are multiple choice, matching and fill in the blank. Following these 58 questions are 6 density problems. The test covers physical and chemical properties, physical and chemical changes, basic chemistry terms (volume, mass, matter, solid, liquid, gas, mixture, element, compound), characteristics of matter, symbols of the elements, conservation of mass, and density.
