CHEM 113: General Chemistry Laboratory I

In this instructional video, we explore the conversion of various pressure units into atmospheres, covering mmHg, bars, Torr, and kPa. The process involves utilizing conversion factors to ensure accurate results for each unit. By the end, you'll have equivalent pressures in atmospheres for the given values, enhancing your understanding of pressure conversions.

Unveil the correlation between molecular shapes and their respective intermolecular forces. Delve into the specifics of nitrogen trichloride, ammonia, silane, and carbon tetrachloride, highlighting their unique force interactions based on polarity.

Understand the fundamental distinctions between pure substances and mixtures. Unpack the definitions and real-world examples of elements, compounds, homogeneous, and heterogeneous mixtures.

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

This video delves into the fascinating world of energy storage in animals and plants, offering insights into why fats are the primary energy storage compound in animals (except muscles) and why plants opt for alternative strategies instead of using fats and oils.

Explore unique strategies employed by prokaryotes and discover if they possess exclusive mechanisms for handling extreme DNA damage that elude eukaryotes."
