CHEM 1411: Chemistry I

In this video, we explore the information that knowledge of the number of protons in a neutral element's atom can provide. Options for determining neutron count, electron count, and identifying the element's name are examined, with a conclusion that it allows us to know both the number of electrons and the element's name.

Converting Denver's average pressure of 24.9 in. Hg into various units. This video provides clear steps to determine equivalents in millimeters of mercury atmospheres pounds per square inch and pascals. Understand the relationships and conversions between these common pressure units.

Delve into the intricate interplay between glycogen synthesis activation and glycogen phosphorylase deactivation. Discover the essential mechanisms that ensure the efficient management of glucose storage and utilization in the body.

Explore the concept of the degree of unsaturation in hydrocarbons. Understand its importance in revealing double bonds, triple bonds, or rings. Learn through examples like limonene, squalene, and lycopene.

This discussion delves into the use of acetone as a solvent for removing water from laboratory glassware, exploring the science behind its effectiveness and the role of hydrogen bonding in facilitating rapid evaporation.

In this video, we delve into the concept of percent composition by mass, exemplified through the compound chloroform (CHCl?), which was once employed as an inhalation anesthetic despite its associated toxicity. By calculating the percent composition for each element within the compound, we gain valuable insights into its composition and its potential effects on health and properties.
