This animation shows the effect of change the volume of a gas phase equilibrium mixture where the numbers of reactant and product molecules are different.

This is the document for the determination of the percent acetic acid in an unknown solution lab.

Part of NCSSM CORE collection: This animation demonstrates the ratio of the combining volumes of hydrogen and oxygen gas to form water.

Part of NCSSM CORE collection: This animation shows how the volume of a gas changes with the number of moles of gas at constant temperature and pressure.

Part of NCSSM CORE collection: This is the document for the conductivity titration of Ba(OH)2 with H2SO4.

This illustration shows a close-up of a section of the band of stability and shows the types of decay a radioactive isotope might undergo to become stable.

This diagram shows the relationship between the nuclear binding energy of an isotope and its atomic mass.

Part of NCSSM CORE collection: This is the student document for the bleach analysis lab.

Part of NCSSM CORE collection: This animation shows the rotation around a single bond in a molecule.

Part of NCSSM CORE collection: This video shows the collection of data to determine the rate law for the reaction of bromate and iodide ions in acidic solution.

Part of NCSSM CORE collection: This is the document for the bromate iodide rate law lab.

Part of NCSSM CORE collection: This is the document for a buffer activity lab. Students will measure and record the pH of various solutions and then measure the pH of the solution after the addition of a buffer solution. They will use their results to gauge the effectiveness of the buffers. NOTE: This lab uses CBL probes and TI-83+ calculators.

This animation shows the separation of a solvent and a solution by a semipermeable membrane, osmosis, and osmotic pressure.

This animation shows the transfer of solvent from a solution of low concentration to a solution of high concentration through the vapor phase.
