CHEM 321: Organic Chemistry I Lab

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

Learn the method to determine the count of SO? molecules, sulfur, and oxygen atoms from a given amount of sulfur dioxide (SO?). Understand the application of Avogadro's number in translating moles to molecules. Grasp key concepts of atomic structure and counting with hands-on examples.

Discover how to determine the final temperature of a water sample after heat absorption. Utilizing the concept of specific heat capacity and the formula q = mc?T, we calculate the change in temperature and reveal its new state. Experience the transformation from an initial tepid state to a drastically altered thermal condition.

In this tutorial, we break down the principle of density, illustrating it as a measure of mass per unit volume. Using an osmium cube as a practical example, we walk viewers through the steps of computing its density, demonstrating the interplay between mass, volume, and particle arrangement.
