CHEM 236: Fundamental Organic CHEM I

Explore the properties of various molecules like diazene, hydrogen peroxide, and carbon tetrafluoride. Understand the influence of molecular shape and electronegativity on polarity. Discover why some are polar while others are nonpolar based on their structure.

Learn the process of determining the density of a rectangular metal bar using its measurements. Understand how volume and mass play a crucial role in the calculation, and the importance of representing results with the correct number of significant figures

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

In this video we explore the process of calculating the weight percent of barium potassium and chlorine in a mixed sample of barium chloride dihydrate and potassium chloride. Through a step-by-step approach we examine the changes in sample weight after heating to 160°C breaking down the calculations for each elemental content.

Discover how to find the molar mass of an unknown diprotic acid through a titration experiment with 0.1288 M NaOH. Learn step by step in this chemistry tutorial.
