CHEM 110: General Chemistry

This video explores the structural and functional differences between sphingomyelins and glycolipids, two types of lipids found in cell membranes, highlighting their commonalities in backbone and fatty acid composition and their distinctive roles in cell structure and recognition.

This video explores the processes of rusting in iron and burning a match, addressing whether the observed changes in mass violate the law of conservation of mass, and explains how these processes align with the law.

This video guides viewers through the process of calculating the volume occupied by Hydrochloric acid gas or HCl at standard temperature and pressure. Using the molar mass of HCl and its properties as an ideal gas the tutorial comprehensively explains each step to determine the volume from a given mass at STP. A must-watch for understanding gas volume conversions in chemistry

Explore the calculations for mole fractions, partial pressures, and total pressure in a 22.4 dm³ vessel with H? and N? at 273.15 K.

Learn about mass changes in an iron bar when exposed to moist air, including the formation of rust (Fe?O?) and how to calculate the final mass.

Delve into the journey of scientific ideas as we discuss how a hypothesis can evolve into a theory, and whether a theory can ever become a law. Uncover the distinctions and connections between these fundamental elements of scientific understanding in this illuminating video.
