CHEM 1311: General Chemistry I

Unpack the difference between quantitative and non-quantitative observations. Examples include a person's weight on the Moon and the depth a hand pump can reach. Learn why precise measurements are crucial in scientific studies.

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.

Explore the power of chemical names and symbols in deciphering copper compound formation at each step of the copper cycle, with an illustrative example.

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.

This explanation delves into the phenomenon where the reaction rate decreases over time due to the decrease in reactant concentration, resulting in fewer successful collisions and reactions, without revealing specific examples or findings.
