CHEM 1031: Fundamentals Chemistry I Laboratory

This video outlines the process of calculating the number of moles in various elemental samples. It begins by explaining the relationship between molar mass and atomic weight. Each sample's mass is divided by the respective element's molar mass to find the number of moles. It provides detailed calculations for four elemental samples: zinc (Zn), argon (Ar), tantalum (Ta), and lithium (Li), converting results to scientific notation where necessary. The script demonstrates how to determine the mole

Explore the fascinating world of intermolecular forces in this brief video, featuring HCl, F?, and C?H?? molecules. Learn about the bonds that hold these substances together!

We explore synthesis and decomposition reactions, showcasing examples like the formation of water and its breakdown into simpler substances. We also clarify that while many of these reactions are redox reactions involving electron transfer, some synthesis and decomposition reactions may not necessarily be redox reactions, as seen in specific examples.

This video delves into the principles of gas behavior at standard temperature and pressure (STP) and how to determine the volume occupied by a given number of moles of gas under these conditions.

This video explains the importance of the number of valence electrons in an element's chemical behavior and demonstrates how to determine the valence electrons for potassium, calcium, and aluminum based on their positions in the periodic table. Valence electrons dictate an element's reactivity with other elements, making this knowledge essential for understanding chemical reactions.
